Long-off 340 build

Well said. I allready mentioned to keep the auto trans but just do an overdriven unit.
The manual trans allows for more cam. Hence my slightly greater duration @ .050 numbers.

I also went the route of a Hyd. roller in my wife's 360. It makes the most sense if you can swing the bucks. It has the greatest rpm range that is well suited for a mild build.

Her cam is a Comp & 224/230 @ .050 and should have 3.55's. The 3.23's will do for now. (26 inch tire)
