KCMongo, im running a EFI 302 V8 in my 89 f-150, and for the most part, it sounds alot like the camaro sound clip on the flowmaster site.
Wow, i like how the diesels sound with flowmasters. haha. I might have to put a head gasket in the 5.7L diesel in my 83 caprice and drive that around with the loud exhaust.
Im not sure how a 235 would sound with 40 series, but it cant be bad.
just gotta get the dual exhaust
