check out the sig for my mods, I've got to get new exhaust again, and I was wondering if I should be getting bigger headers first or if my 305 headers are decent enough?
I'm going 3" single into a flowmaster 3 chamber.

I have 1 5/8 headers on my Vette headed 350 and I love them! Don't believe everything you hear about bigger is better. My friend builds engines for a living and he has a 1970 blown BB Camaro and he is running 1 1/2 primarys, the thing runs like a bat out of hell. Plus if you stick with the 1 5/8 headers you will have more clearnce around your steering shaft. So what if you lose a couple of HR with them, you can easly find the HP somewhere else.
