71 bb exhaust
I have a 71 bb corvette that had a zz4 crate engine in it but took it out (car is a original bb car) to put 454 back in corvette. Engine is done and installed. Exhaust system in corvette is 2.5 and a set of flowmaster 40s(running stock exhaust manifolds ,engine somewhat stock roller cam nothing to fancy) 2.5 sound big enough??
