Finally finished after 231.5 hours . I always wanted to do this build since I was a 13 year old kid. I was into auto racing big time, and about the only source I had for news and pictures were magazines. I had a subscription to Sports Car Graphic, Motor Trend and Car and Driver. Whenever there was anything in a magazine about racing , I would cut it out and put the pictures and story in 2 scrap books. One for Stock car racing and one for Sports car racing and Indy cars. I still have the scrap books today but they are falling apart from age. I just happened to be thumbing through the sports car scrap book and spotted the story about Roger Penske's victory at the Nassau Tourist Trophy race in the Bahamas in 1964. His Grand Sport looked so awesome, I knew I had to finally build a replica of it. Turns out the race was a battle between him and Ken Miles of "Ford vs. Ferrari" fame. Mile's 390 Cobra could pull away from Penske in the straights but Penske's Grand sport would catch up in the turns. Miles Cobra finally blew up trying to stay ahead of the powerful and nimble Corvette. I learned alot about the car. It had a 377 cubic inch all aluminum engine with 4 weber side draft carbs and hemi heads . It basically was a 327 stroked a quarter of an inch to get to 377. it pumped out 485 horsepower. This is an amt kit because I did not know there was a much better kit, until I started the build and was informed of this, so I had to do a lot of scratch building. The wip link is at the bottom of this page.

That's a fantastic job on converting that AMT!

The 377 is a half inch stroker in the 327 block, 3.75" stroke and 4" bore. My brother ran one (but not aluminum, just a normal cast iron 327 block) in a Supermodified in the mid '60s before the factory ever made a 350 engine.

actually I read that a 327 was 3.5" stroke. that's why I said they stroked it a quarter of an inch. Must have been bogus info.

Mark - Great job on the AMT kit, not the easiest to build this well!

FYI - 327 (both small and large journal) had a 3.25" stroke, 350 (up until 2001) is 3.48"

Thanks, John. I saw your 1970 Camaro post yesterday, somewhere, but was too tired to respond and now I cant find it, so kudos on that beautiful build. Paint is outstanding as always.

Mark, If you took away all the mods and extensive scratch building there might only be a handful of parts left.
The WIP on the MCM site is a tutorial on how to make something great out of nothing.
I don't have the skills to do something like that so watching a master sharing his work methods is a pure delight and very inspirational
I salute you sir!

Thanks, Pierre. If I had been able to get a real Grand Sport kit , I would have, and I knew once I started, I would have been shown a way to get one , but once I start something I feel like I have to finish it. Then again its hard to believe I could have gotten a Historical Racing Miniatures kit for ten bucks from ebay when I saw what they were going for on the internet. Its kinda fun to try to create a few parts here and there even though their not quite right . But you get the idea what they're suppose to be. My next build will be changing a 70 and a half Camaro into a 74, And I have to make the wheels for it too. I've already created the decals for it. Thanks again for the kind words.
