I made a short sound video of the modified GMC 302 in my 37 Chevy PU.The engine has typical hot rod modifications,the exhaust is a single 3 inch pipe,Flowmaster 70 series muffler.You probably need broadband internet to see and hear it.Maybe some of you can post your engine sounds here also.I used a typical digital camera with sound and movie,posted it for free on You Tube.
