Here is the trick. I started with a two seater Ferrari GT 212, all aluminum body and wire wheels. When the original 12 cylinder engine spun a crank, the previous owner decided to build a less expensive 301 cubic inch small block Chevy with ported heads and Isky roller camshaft.
Instead of a traditional air cleaner (insufficient space), the engine was fitted with 3 two barrel carbs and velocity stacks sticking into the hood scoop. The headers and exhaust system were all formed from custom bent tubing, no mufflers, just twin collector boxes with dual 2" pipes from collector to the rear bumper. Rev capability and sound was wonderful with the roller cam and lightweight Schiefer flywheel assembly.
I have photographs of it, metallic silver with red interior. It was VERY sparse, no radio, no seat belts, with Plexiglas side and rear windows that did not roll up or down. The seats were little more than frames with a thin sheet of leather over them. The car did not even carry a spare tire. Add to that, it was right hand drive, the flaw in the car that made it uncomfortable for me to enjoy long term.
Still it was fun for the $3600.00 I paid for it. It would be worth a small fortune now.
