Tom, I think you would be happy with the 2 1/2" exhaust. That's what I have on mine. Bored 40, Gary P cam, mild port on the heads, TTI headers, TTI 2 1/2" exhaust. A big block guy here tried to get me to buy the 3" exhaust. I had to remind him that I only have a small block. This set up works well on my 64. I still have the stock gear in the diff, but it will be changed to 3.73:1 soon. Even with the stock rear, it performs well!,. I gave my buddy & his dad a ride in it, and both were impressed! in fact, his dad tried to buy it!!!! POLY'S RULE!!!!! (At least until my Max Wedge car is done) Bob K -- [Non-text portions of this message have been removed] ---- Please address private mail -- mail of interest to only one person -- directly to that person.
