I was planing on using dual Ron's terminators but it is an money issue so i tought that I'll use the carbs to start with, and see how it works.
I will spin the motor 6500-7000rpm and canot use that much boost because I will run on pump gas.
I have gone over the stroke in my head many times and always as confused... but I think that I'll go with the 4.5" because I have that all ready and I have 17" wide slicks so I hope that they will grab atleast something.
