Hey guys, New guy here. Been working on old cars for several years(ASE Certified) I have a question. I just bought a 78 camaro LT with 350/350 combo. starts up great, great idle, and runs good except when it ie opened up. When I get onto it it starts backfireing through the carb. The car is mostly original. I have already put a new Edlebrock carb and intake combo and a new Accel Blueprint HEI distributor. The ingition timing is right on an so is the air/fuel ratio and idle. Any ideas? Also, Does anyone know a site that I can research some engine and head casting numbers?
Thanks,
