Engine had 800 miles on rebuild, looked great on the builder's invoice, SpeedPro stock 11-1 forged pistons, ARP bolts in re-sized rods, balanced, new vales and guides etc. Oil came out looking like liquid graphite, sludge in filter. And pan. UH OH! Bearings were down to base metal, crank had grooves, five rods out of round, loose valve guides and grit everywhere. After a back to basics rebuild put up great numbers on the dyno and break-in oil came out clean. Runs great and runs to redline with confidence. Save your nickels and dimes, get a competant engine builder involved, no short cuts, and it will be good for another forty years! ![]() |
