This car was my Dad's car, he passed when I was 12 years old, my mom didn't drive and I became the family driver. Back in 1962 I put a v 8 in this car, 283- bored 1/8 th to 301 cid -- edelbrock ram induction 2 AFB carbs, fuel injection heads with 2.02 intakes 1.67 exhausts , Mallory dual point ignition, iskey Z 50 cam -- largest flat tappet cam at the time ,11 1/2 to one pistons, this was balanced by C-T automotive in Calf, hand built tube headers into a 4" collector , with a B/W T 10 4 speed trany, 4.56 rear end, Hurst shifter, I was 15 yr old at the time. The fastest car in high school. When I went in the Air Force I was stationed in Tuscon Arizona in 1966, it was upholstered in Nogales Mexico. This car has always been a nice car, I've rebuilt this several times, now that Iv'e retired this is getting the full Montie frame off resto , pulled the 350 - turbo 400 and has a 2012 Camaro 6.2 lt Ls3 -6 speed manual trany with a 2012 camaro interiour . Lots of work, keeps me busy, and a lot of memories in this car and fun. Larry :D Buy the way the Rocket is still running great, with 48,000 miles on it with very few problems--- minor wiring problems-- runs great.

Wow larry, you always take on the "easy" ones don't you?

seems to be that frame should get some reinforcement to make it more stiff and strong, 500 hp will put a lot of stress on that old chassis.

On a car like that, you are not limited by any federal requirements, so you can do any improvements unrestricted. Well, it still needs break lights and tires with tread, but not much else.

That Generation Chevy coupe was always the best looking of the body styles - even beating the 'vert!
I had a good buddie in HS ('58) who had a '51, but with Power Glide - unbelievably slow with that slushbox! He always, but aways, started in Low. I think the early PG had only two gears forward?

Thanks for the input guys. Peter the frame is fish plated both sides over the rear end to beef up for the rear Triangulated sup, re-enforced inside the frame for the mounts and all Tiged welded including the Camaro subframe that I grafted on in 1988. This has always been a nice ride--- this time around it WILL be a lot nicer----- told my wife this my new Chevy Silverado 4x4. Larry
