Can this be done? Has it been done? Is it difficult. Thought maybe it may take some worries about the core shift out. Just throwing the idea out...
Sure, it can be done. Not so much to correct core shift problems (no fix for that, that I know of), but for oil control when using roller lifters. Seems dicey to me though, as the lifter bores are already a weak spot, and reaming them out for a sleeve is only going to further weaken them. Geof Ketchum may have some experience with this, try getting hold of him at FinishLine Motorsports. -Ron
thanks. What if we used a strong metal though? Maybe like Ductile Iron? Just throwing ideas out there.. thanks for the info Ron.
Re: thanks. Just remember here that the passenger side lifter galley is also the oil feed for the crank shaft, so putting in a bushing, like for instance a ductile iron or steel unit, it would have to be firly thick, this in turn would cut down the oil galley size that feeds the crank, big mistake here. This is one of inherent problems with the current block. The new block that we will be introducing very soon will of course address this concern as well, since the crank will no longer be oiled from the lifter galley. There are only so many bandaides that you can do do the current block. Jim Burek P.A.E. ENTERPRISES
