Solid lifter/bushed lifter bore question

Solid lifter/bushed lifter bore question - 01/25/11 09:37 PM

I'm building a low deck 512 with girdle and bushing/re-aligning the lifter bores. I plan on using a solid lift cam (old STX 22) with mushroom lifters. Do I need oiling holes in the bushings. Thanks in advance, Mike.

IF YOU OIL THRU THE PUSHRODS

My is to go ahead and drill them. My undrilled bushings showed some odd wear patterns that might have been indication of insufficient lubrication. I've since drilled them to eliminate that as a possibility.

make sure holes are located exactly as for lifters used. . wrong and you could experience loss of oil presure

I like to have a small hole drilled in them for some lube, a little running down the lifter onto the cam on a flat tappet isn't a bad thing .

My 440 block has .030 or .060(can.t remember which size ) oil holes in them, it is a solid roller lifter motor not oiling through the pushrods to the rockers.

I'd put a small oil hole either at 5 oclock or 7 oclock. You don't need it that way for the solid lifters, but you'll want it that way if you go to a roller lifter down the road.

Thanks, guys/ An old timer said I didn't need them with that cam, but didn't say anything about pushrod oiling. Mike

Well he is correct, you don't need them for that cam. Then again, a year from now you might want to change cams. Pays to think ahead sometimes.

If you think you might want to run an EDM lifter (I wouldn't run a solid cam again without them) in the future it would be nice to have the oil hole. The EDMs also oil through the pushrod.
