My car is a 69 Camaro RS and I currently have a 383 SBC with a 700R trans. The MSD distributer cap is probably a 1/8" from the firewall. The cap is a std GM cap.
A friend of mine is currently building a 69 Camaro Z28 clone. His subframe is in with his 302 and 4 speed. No front clip yet. Stopped by and looked it over this morning and he has about 1.5" of clearance between his distributer and firewall. We parked my car in front of his car and kept looking back and fourth, all looks to be the same (engine mounts, position, etc). We could not figure it out.
Side Note. When finishing my car the new driveshaft was about 1" to long so we had it shortend to fit. Now I am thinking the driveshaft was correct and somehow my engine is sitting to far back. Any ideas, refferences, what to measure, etc?
