The five Corvette Grand Sports were a response to the Ford Cobras and “European” racing cars of the early 60s. Although they appeared very similar to production Corvette Stingrays, in reality, there were very few production parts in the Grand Sports. In effect, these were hand-built and purpose-built race cars.

The factory’s goal was to make them as light as possible and they accomplished this in many ways. For instance, the body was lightweight. It used a different construction technique, allowing for a thinner fiberglass body, plus was not gel-coated (to save weight), which resulted in it being translucent.

As another weight-saving measure, most of the production stamped steel, cast iron and steel forgings were replaced with aluminum components. And then there was the chassis. The heavy production model was replaced by a light, mandrel-bent, thin-walled chassis, while the suspension components were special built or lightened with a series of holes. So, what they ended up with was a car that was definitely a Corvette Stingray, but one that was around half a ton lighter than the production model.

Building The Kit

Accurate Miniatures (AM) has done an excellent job engineering their 1/24^th scale Grand Sport Corvette models. However, it is definitely not an easy to build kit. It is a highly detailed model and not for the faint of heart. The instructions are OK, but don’t always give enough information. If you want to build one of these models, I’d recommend you check out the

website. It is invaluable, as it has a several articles on restoring the Grand Sports, complete with many pictures. Using those articles and being patient will allow you to build a very nice model of one of the rarest Corvettes, ever.

The guys from our local model club, FRAM (Front Range Auto Modelers), took this kit on as a club challenge. Ken Kitchen built the chassis; Bill MacKirdy did the engine, Jeff Conrad massaged, painted, and decaled the body, while I did the interior and the final installation.


Engine: The engine block is molded in two pieces which requires filling and sanding the oil-pan to get rid of the joint. Once that is done, it builds up rather nicely. It includes four Weber sidedraft carburetors complete with a delicate, but nice looking carburetor linkage. The instructions call for the linkage to be bent slightly for an accurate installation. I was not able to do this without breaking the linkage. However, it was easy to repair. The only other challenge I had with the engine was with the headers. They have mounting pins to facilitate correct installation, however the heads do not have corresponding holes. I corrected this by sanding off the mounting pins. A second challenge with the headers was fitting them around the chassis rails. On this sample, the angle was too shallow—I had to open each one up slightly. Like the carburetor linkage, this was difficult to do without breaking them.

Chassis: The chassis and suspension are probably the most difficult part of the model to build. And, the chassis has the most glaring problem of this model. It is molded with voids in the bottom of the tubing. These must be filled to provide an accurate representation. Another challenge with the chassis is how to mount the suspension components and the radiator hoses. I had difficulty figuring out which radiator hose was which—don’t separate them from the sprue before you install one or you may end up reshaping them both, as I did. My advice is to, once again, check out “Racing Icons” website. There just isn’t enough detail in the instructions to accurately position the various components.

Tires: The instructions call for the tread of the tires to be sanded to look like they are race-worn tires. I did this, but it wasn’t as easy as I had thought it would be, as the tires are made in a two piece mold and, in the case of my sample, the mold marks were clearly evident. This was compounded by the tires not being flat across the tread. At any rate, I was able to complete the task and the tires definitely do look better when the tread is not “shiny and new”.

Interior: The interior went together very nicely. It includes a clear instrument panel which I detailed with matte black, silver, and red paint. There is a black decal for the back of the clear panel—once assembled it looks fairly realistic. There were two sticky points in regard to the interior. First was the gas tank; I wasn’t sure how to mount the gas tank, but after looking at it more closely I found an arch which corresponds to the hump for the transmission. The second headache or more accurately “eye straining” part was the photo-etched pieces for the driver’s seat belts. I had a dickens of a time with them as they are very small—too small to be held in your fingers. I was finally able to thread a piece of ribbon through them using a pair of forceps and tweezers. Then I had to figure out how to mount them (the seatbelts). The instructions weren’t any help and I couldn’t find a picture of the seatbelts on the seats. I finally made a command decision--since the Grand Sports were built in the early 60s, I decided to depict a lapbelt only.


Body: The body is nicely proportioned, with fairly clean moldings. I was surprised that the mold seams are so large for a kit that hasn’t been re-released before. The largest seams to deal with are near the rear of the side window and near the rear wheel well arch. The biggest challenge with body prep are the sink holes in the hood. There are 2 holes in the front and some “waves” in the back part of the hood that need to be addressed before painting. Overall it took about 3 hours of body prep on this model.

Photo-etch: You'll need to be careful with the oil cooler cover – the bend lines are scored so deep in the metal that it is very easy to break this piece, especially on the hose side. Once broken it is very hard to fix (I know, it happened to me.) I finally used the plastic piece, thinning it down until it looked more realistic. The P/E scripts are excellent and easy to use (make sure you sand off the Corvette script in the back before painting.) If you’ve used P/E before there won’t be any surprises here. If not – get some experience before attempting the oil cooler cover.

Decals: The decals are very thin, and they respond well to Micro scale products. The white is opaque and the numbers and contingencies are well registered. I used Micro Set and Micro Sol to get the roundels and numbers to conform to the curves of the body. When done the decals look like paint. One downside – there is no Goodyear decal for the doors, so I had to grab one from the spares box to match the car as run in Nassau in


Paint: I used Nassau Blue Metallic from the Model Master custom lacquer system (#) over a coat of Tamiya fine white primer. After getting the paint smooth I applied 3 coats of Model Master Ultra Gloss Clearcoat (again from the custom lacquer system) until I got a nice, medium shiny gloss (not too glassy, as it is a race car.)

Glass: nicely molded, no distortion either. Easily installed without problems.


Final assembly was quite a bit more “fiddly” than the usual kits I assemble, mainly because of the close tolerances it was molded to. The interior is wider than the bottom of the body—as the instructions say, gently spread the sides of the body and slide the interior to the front until the mounting tabs in the back snap into place. I used the photo-etched brake booster bracket (which mounts on the firewall) and this got in the way of one of the carburetors when I installed the chassis. I had to (gently) push the engine to one side as I pushed the chassis into place. Then I glued on the exhaust assemblies and the tires.


One of the last things I did was install the front turn signals. These are tiny and AM wisely provided four of them, even though only two are needed. (I lost one of them during installation). Once I separated them from the sprue, I found they were almost too small to pick up. I got around that by wetting my finger and using “surface tension” to pick them up. I fastened them using “Elmer’s Glue” which gave me time to position them correctly and prevented them from hazing over.


As you can see from the pictures, once everything is assembled, it really looks like the real thing. I think I speak for everyone in our club when I say we highly recommend this kit. Just keep in mind that it is not one for the beginner or even the intermediate builder. It is a challenge to build cleanly, but be patient--your efforts will definitely be rewarded!

My sincere thanks to Accurate Miniatures for the review sample.

How To: Build Your Own Corvette Grand Sport


The early ’60s were a turning point for the high performance world when engineers at Chevrolet, Ford and Chrysler hustled horsepower to maintain track dominance.


It was also a time when legendary engineer Zora Arkus-Duntov secretly developed the C2 Corvette as a cutting-edge racecar—the Grand Sport (GS). The GS featured a ci V-8 and an aluminum, tubular space frame for a wicked power-to-weight ratio. Known as the ‘Lightweight,’ GM, sadly, cancelled the project after only five, of a proposed , GSs were built making them one of the rarest Corvettes ever. GM ordered the cars destroyed but Zora put away the first two cars, and sent , & to John Mecom of Houston, Texas. John sold the three cars to Texans Alan Sevadjian, Delmo Johnson, and Jim Hall respectively.

In the 80s, people were still racing original Grand Sports but they have now become too valuable.

Meanwhile, year-old Charlie Ranfos of Candia, NH was working at his uncle Angie’s Chevron station in Manchester. The station was a hotbed of activity behind which Dave Parris ran small shop hopping-up muscle cars. Sharing the same enthusiasm for Chevrolet performance, Charlie wasted no time in getting into the game once he got his license.

Eventually, Charlie opened Auto Trim, Inc., in Candia, focusing on custom upholstery for classics and muscle cars and C2 Corvettes in particular. His first full restoration was a big-block Mosport Green ’66 roadster followed by a ’67 big-block roadster for his wife Marleen. For himself, he decided to build a GS based on an original Corvette.

Charlie’s search for a C2 donor led to a rolling basket case ’66 coupe sans engine and trans. The chassis was disassembled, blasted and brought to Ron Gagnon at New England Rod Shop in Bedford where it was fully TIG-welded and gusseted for extra strength. Gagnon also crafted a fresh rear crossmember for the updated C3 IRS with gears, a composite monoleaf and Vette Brakes & Products’ tube shocks. Also added were rear offset trailing arms from Vansteel, Inc. and a factory sway bar.

Up front a manual steering box works flawlessly with updated upper and lower control arms as well as a composite monoleaf and tube shocks along with a factory sway bar. Plenty of braking performance is supplied by C3 Corvette discs and calipers all round. Linking it all to the street you’ll find PS Engineering Grand Sport wheels complete with custom machined hubs with knock-off spinners and safety pins plus BFGoodrich Euro T/A rubber.      

Under the highly sculpted hood resides a ci block massaged by R&L Engines of Northwood. It’s fitted with a stock, forged-steel crank and refreshed factory rods topped with forged aluminum Speed Pro pistons. A Comp Cams Street Roller stick sets a heavy beat. A set of World Products’ Merlin iron heads are fitted with Manley Race-Series stainless valves. Up top a cfm Stage 3 Holley by the Carb Shop feeds a Weiand dual-plane intake. Ignition is Accel and spent gasses are dumped through a set of Hooker Super Competition headers into 4-inch matching side pipes. The trans is a rebuilt Muncie M22 by Old School 4-Speeds of Springfield, VT.


Mid-America Industries supplied Charlie their GS-2 Grand Sport kit, however, these components from Nevada Classic, LLC are shown for reference only.

When sourcing restyling parts Charlie contacted Mid-America Industries, Inc. for one of their GS-2 Grand Sport conversions who offered nearly everything needed for the visual transformation. Working with good friend Joe Gillooly, the pair started by carefully removing the front and rear clips. To give the car a very distinctive look Charlie had Ron Gagnon work his magic on the hood by adding custom stainless louvers. The doors, trunk, and hood were then fitted and all gaps were dialed in to make sure everything was perfectly balanced. This included modifying the original doors with updated door handle recess panels, installing the fuel filler and glass. From there the pair made the body razor sharp and prepped it for paint by Ron Lavoie at Eastern Auto Body in Manchester. Ron laid down an immaculate coating of PPG Glenn Green accented by a Gold Sand Poly stripe.

The cockpit is all business starting with a custom dash from Mid-America, filled with factory gauges including a stock speedo recalibrated to mph. An original Corvette 3-spoke steering wheel carves the course while a Hurst Competition-Plus shifter pulls gears. For comfort, Charlie covered a pair of ’68 Corvette buckets in saddle leather and equipped them with Simpson Racing 5-point harnesses. Inside you’ll also find custom aluminum panels by Mike Curley along with a 4-point rollcage and ATI fuel cell with custom fabbed mounting straps and fill tube by Ron Gagnon.

Throughout the build Mike MacCallister added plenty of mechanical expertise to various areas and Jay Doerfler of Auto Body Specialists in Manchester dialed the car in upon completion to make it road ready. The build spanned more than 1, hours over a year journey to create a visually striking C2 Corvette paying homage to the original Grand Sports. Seeing, hearing and watching it in action proves it’s as real a deal as can be.
