Response to Lifter Bore Bushing oil holes

 

With a bit of luck Wink will chime in on this. Ive done 4 blocks with winks kit, 3 race only with the 43 thou holes (one of them big solid roller).

The other one that does a fair bit of street time we went with 060 holes in the bushes (went with 060 as it was mentioned in the how to build sbf book). The build is more race than street but its done several thousand HARD street k's, flat tappet, mid 260's @ 050, 400pnds on the nose. Grouted block, big 3+" bearing clearances. Didnt use cool face lifters.

This thing isnt mine and I havent checked spring pressures since it left here,but if there were a problem this guy would find it. NO mechanical sympathy. With the 060 hole, grouted block and big clearances it suffers low 25pnd oil pressure at idle, but is showing no other problems. Oil filters are clean. Youtube below is of the owner with a previous engine, this one gets the same treatment.....but with more revs:)
