Brian asked about the V6 lifter. After rereading your post, I assume you are using the V6 lifter retainers, but V8 lifters?
At that point, is there a difference? I mean, the V6s share some internals with V8s, why not lifters?
I am using V6 roller lifters and V8 retainers and spider bar. The Gen1 blocks have shorter lifter bores than the later roller blocks so the V8 lifters, being taller than V6 lifters, lift up too high out of the Gen1 lifter bores. This creates several problems...all solved by using shorter V6 lifters.
The benefit is a cheaper roller conversion and the reliability of the stock retainer system, which I like better than the after market stuff.
cool learn something new everyday
Yeah and actually, I made the mistake of originally choosing a stroker style small base circle roller cam because of the stroker rods I was using, and I found out the small base circle came DOES NOT work with the V6 roller lifter swap.
The small base circle cam lets the lifters fall too far down in the lifter bores. Not only do they almost drop out completely from the retainers, but the oil feed holes that pressurize the lifters don't actually ever make it up into the bores fully so there would never be full pressure.
Quite simply, V6 roller lifters can not be used with small base circle stroker cams in Gen1 small blocks retrofitted for the V6 lifters. Lesson learned. LOL.
Now, the Comp cam I am looking at is a standard cam diameter so I can use it, but I will have to grind the rod bolt stud heads so they won't contact the cam. Once that's done everything should work together fine.
