Proper Exhaust Diameter fo a 4bbl 225?

Sorry for being absent -things got crazy this week. Thanks for all the advice everyone/'';'

. Sounds like the single 2.5 pipe is the ticket, and the paint stripe trick is very cool. @Darter6, what's a converter?:p

I'm in Eugene, and my shop is Joe's Garage. I'm pretty new at all this, and the guys at joe's are good at helping me understand things. I don't have a lot of money, picked the car up pretty cheap, got the 4 barrel Holley (not sure of the CFM) and Clifford intakes and headers and promptly blew the engine going way too fast for way too long on the freeway. Hence the rebuild. Totally worth it, except to my wife :p.

It's a three on the tree, manual steering, base model, no frills and getting in it feels like coming home.
Nice in Eugene, I’m over here in springfield. Joes Garage is a good place from what I hear. I’m no slant six expert but if you ever need help just shoot me a message on here. Dustin.
