You will have to bore the block to fit in the 450 sleeves which the OD is 4.25. Dad n I used to make tall domed 450 piston n sleeve sets, that used a .500 tall dome. I think I still have a set here if youd like to see em. Ive seen em dyno 75hp with a 8060 head n 450 cam. seen em dyno over 85 with the LP head on high octane fuel. It aint no 600ci billet monster, but makes for a mean 281ci motor. Hope this helps. Chad [Reply]   [No Email]
