Thanks guys for the quick replies and advice. I will change my coil springs and get a chevy bell housing and another gear box since right now I have a saginaw. I still want to yank the whole motor and trans out complete with the existing engine harness. Its all factory stock and I want to keep it all together in case i want to put it back to stock? Not!! but you never know. Also I would like to build a Pontiac 400 or 350 but living in Los Angeles these engines are quite expensive just as cores. So since I have a 327 and 350 complete from oil pan to carb I want to use one of these engines first. Thank you firebird69racer for loading the pictures. I had no idea that there were different frame mounts tall and low. I'm not up to date on the headers these days. do they offer a long tube header that has good ground clearance? for a lowered street driven car?. OK guys I'm back to the question? will a 68 chevy camaro/nova v8 engine harness bolt up and be functional/ compatible to my 68 firebird sprint firewall? I really dont want to hack or alter my 6 cyl engine harness. Thanks.
