rtstrack 427 cammer is # 3, #2 is the shotgun Kasse motor in the 598 cubes, and number #1 is a stroker windsor in the 393-427 range in Aluminum. If you want to go cheap, I know I am going to hate myself with this one, LS7 or LS9 GM motor. LS2 with a 454 cubic inch stroker kit does it all. I have to go wash my mouth out with SOAP.@#%$#@@$%% Rick L.
