Replace lifters? Barbell? Oil pump? If you've seen my other posts you know that my motor has a spun cam bearing. I'll be getting it checked this week to see if it's salvageable.
Assuming the news is good; Question is should I replace the lifters? It's getting a new cam of course, but the entire motor is very low hour, so I was planning to use the old parts as much as possible, that plan seems to be going down the tubes.
I pulled the crank and there are some scratches on the mains, also going to have the engine builder look at those for his advice, I assume polishing at least.
Was going to use original rod bearings, they looked good, but going with new instead. Leaning towards new lifters also. Of course new mains.
Secondary question, which barbell? Motor is race only, but not super hot, stage 2 cam, VVT delete, forged pistons, planning to stay around the 6k redline, expecting 450-500hp.
What about an oil pump, stick with original, go with aftermarket, Melling???
I'm new to the LS world, but not to wrenching.
And again, Thanks to all.

Plus…it’s super hard to get all the metal debris out of lifters. I’d go new lifters, but that’s my opinion. That spun cam bearing put debris everywhere in the oiling circuit…clean or replace everything.
