I have always wanted to take a mellow approach to a 4.5 build, ... Stock 3in main block, out of the box 85cc E"heads adjusted to 10-1 compression, Obviously great rods and pistons, Crower 60919 cam with 1.65 rockers, decent intake and exhaust tracts, stock stall converter with a 2.56 gear out back and drive the pants off it....... Seems like the 4.5 arm is less suited for high RPM and longevity this case would dimmish both inherent shortcomings and still be enjoyable to operate... .. I already have the crank and block.
