I've got a 56 261 bored to 270 with Fentons and 2 - 1bb carbs. Milled 848 head. A few other things.
If I find the 3.55 to be to high, I can go to a 3.73 by swaping the center section out. It's a 55 Chevy car rear end and it's a Powerglide so I could go to a standard 3.73.
I feel fairly good about the set up. I'll know, of course, after I get it on the street!
Thanks for you comments and help. Let me know if I can do anything for you!!
Joe
