I have a 400 sb with 350 crank and full roller valve train and alum heads, lots hps lol. I has the 1.75in headman pro comp headers going in to 3in pipes with 2.5 cross over to 30in? glass packs to turn downs at the front of the rear swing arms, sounds like a stinkin stock car, real nice! i also had a 76 c30 with 292 had a 3in mandrl system with glass pac and turn down sounded like bumble bee, then i put 5in semi tip on it lol it was real annoying and unique lol but 3in in the way to go
