Bought a 67 Camaro about 1 and a half ago, been doing a complete restomod and finally have the body work done, exept paint(its in a black tinted sealer right now) and the engine is build and running, im ready to redo the exhaust, headers are leaky on the new high speed aluminu heads, so im gonna upgrade to hooker super comp, 2inch primaries 3 1/2 collectors. then do a h pipe with a 3inch pipe and flowmaster super 40's. Sound make it sound awsome, but i just recently found out the transmission crossmember has to be a big block, now i only have a th350 in there and all the big block crossmembers are for th400. will it still fit and does anyone know of a good tubular crossmember?
