Solid lifter a "no no"?
I am being told by a few people that the 460's have an oiling issue where the passenger side lifter bores need to be bushed/restricted. I was told that this issue comes into par when you run a solid style lifter. So that being said, I am about to get a cam and wanted to ask the question. Has anyone here ever heard of this issue at all? I never have, and I would prefer a solid cam. It is a street car but I'm going for all out performance and I already check lash frequently.

The issue is that if you loose a lifter from the lifter bore you will loose oil pressure, because stock block 460s oil the lifter first then the mains.
It's not normally a real problem, but some builders do like to bush the lifter bores to restrict oil to the top end and true up the bore and allow larger lifters to be used. Plus lifter busing are much easier on lifters.
Down side is the bushings are not cheap, but the vast majority of builds live long and productive lives with out ever being bushed.
And yes it does sound like youre talking with a Chevy builder, majority of ford builder would only do it on high end builds if they bothered at all.

Dave ... that would be true with ANY lifter not just solids.

Factory 429 SCJ had solid lifters and no bushed bores. I put over 45,000 miles on mine with no lifter problems. Checked lash once a week.

Tell those "few people" that Ford guys have made thousands of horsepower without bushing their lifter bores.bb429power wrote:I am being told by a few people that the 460's have an oiling issue where the passenger side lifter bores need to be bushed/restricted.

To go even further:
IF you were to bush those lifter bores and NOT increase the diameter of that oil gallery BEFORE installing the bushings, there could be an oil starvation problem to the bearings at very high RPM.
There is a lot more involved than simply putting bushings in the lifter bores.
