the only thing I see that looks odd is if you look into the muffler I have for 2-1/2" pipe it necks down to less than 2" on the inside...ive also got a set of dynamax knockoffs im gonna try...were gonna run both sets on the dyno and see if theres any diff..

Let me know how it works out.

Nothing radical at all, just a GM Goodwrench 350 #10067353 with a 256 cam and Vortec heads
