With the single plain and aluminum flywheel setup, driving was brutal. I switched over to a progressive linkage just to make it work. Even then I was not satisfied, so much so I was gonna go back to a 30lb flywheel to smooth it outI didn't think a dual plane would be all that noticeable on a boosted 540.
those on the car right now are a 295/55r15 on a 15x10 rim. Street tires are a 275/60r15. New slicks will be a 28x10.5If you don't mind me asking, what size tires are those drag radials? or race tires? thinking of trying 305/45r17" on my 68, and what compression is your motor for using boost?
