I don't know whether it's feasible, but the Mopar lifters are the biggest diameter, at .904".

If that would work for you, and bigger is better, it might bear looking into.

Then again, maybe that size won't work in your engine... Check it out.

Wrong again, Mopar not biggest @.904 Oldsmoble had lifters @ either .924 or .930.

If you are in eastern NC you should contact Doug Hobgood @ H & F Performance in Wilson, NC. They do our engines and many class racers from this area. You won't find nicer people to work with. Their number is 252/243-2050.

Thanks for that information. I am sorry for the mis-information. I wasn't aware of the Olds lifter diameter.

Was that ALL Olds lifters, or just a select few applications?.

Can not remember which was which as some blocks had different lft bore bore angles.

Whoever does lifter bores will tell you probaly to do all of them. Many sbc won't clean all bores up
when correcting locations{blueprinting} when just going to .875 ford .904 will usaully clean up all
of them I would recomend put bronze bushings in they will last longer than non bushed holes.The
bushings are 1'' O.D. and can prep the I.D. for whichever size lifter you want. Make sure whoever
does it has fixture that corrects location like BHJ as example or one the newer CNC machines
that does lifter bores and everything else like Rottler F65 etc.I remachined BBC one time guy
had me dyno I did heads so I knew how much power he should have from flow numbers.it was
way off and engine was too hard to rotate.He said fix it.tore down, checked lifter bores W/ go/no
go gauge on BHJ fixture they had just been bushed by somebody they were off had to go .842-.904
to correct,rehone cyl. redeck block was out square leaking head gaskets dyno time only.rebalance
long story short remachine whole short block. With no other changes besides machining picked up
60 HP
