SBM Roller Lifter Choice
Here is a list I found of all different roller lifters....older list, but useful.
What roller lifters?
I just read this link. It is excellent, although it needs to be updated
To reflect current offerings as it's going on 8 years old.
IMHO this link and the pics and info in post number 4 should be made a sticky in the engine section. The link explains at the end, how to prepare a sbm for use with a roller or which type rollers from which manufacturer will work with a given setup.
Too many members getting this info after they have trouble.
The old Chrysler engine book explained all this many years ago, but
Still there are members not familiar with this problem.
Also too many manufacturers claiming to have a drop in no mod hydraulic roller lifter, which is not always the case.
Post number 4 has good pics that show the relationship between
The lifter bore and lifter, and the drilled(not always correctly) oil galley. The link also points out that in a performance build, a valve train failure on a block with no tubes or bushed lifter bores will cause a huge drop in oil pressure that could damage other parts of the engine. The guy who did the leg work for the link, hats off to you.
