Thanks, me too. I'm not the world's best engine builder, or the world's best anything for that matter, but it would be a lot easier, less expensive, more fun and a lot less frustrating if one could purchase quality components that consistently performed as advertised. Most aftermarket stuff I've dealt with are not anywhere near as good as factory parts and no where near as advertised. "one part fits none"
Seems some roller lifters for Pontiac used Chev bodies, the oil band would drop below the bottom of the lifter bore, when on base circle, and the oil would drop out, thus no pump-up. The lifter could then catch on the bottom of the bore leading to lifter, bore and ultimately engine failure. That's bright! In order to get a very high-lift cam lobe to fit down the cam tunnel the base circle may be ground smaller, that would result in the lifter dropping even lower in the lifter bore.
Seems Comp is buying lifters with a Pontiac design body now but the quality is still not there.
First thing is to ask the cam companies if they make their own lifters, if not shop somewhere else. Next is to ask them for all the dimensions and if the lifter body is Pontiac specific or a re-worked Chev body. Kind of a pain in the rear, should be able to look in the catalouge pick what you want order it up and drive. Should, but...
I've talked to Crower about their lifters and may try another hydraulic roller or switch to solid lifters.
I read on another Pontiac site one guy has the same cam as mine, put in a set of solids and it solved his lifter woes. Just waiting for him to get back to me with the rest of his car and engine specs to determine if that is a route I should take.
