Which lifters?
All parts are in to begin building my D1 ProCharger forged 408 cid engine.
I am looking for advice on which lifters to consider.
My brain thinks that the GM racing roller hydraulics will be fine. ($300)
My builder thinks I should eliminate the plastic lifter buckets and use a bar type roller ($800). Of course,he keeps using the term " good insurance" and so far this " term" has cost me about an additional $1500.
I certainly don't want to be penny wise and dollar foolish, but my paranoia is beginning to get expensive.

But, my builder showed me a broken lifter bucket that allowed the roller to turn sideways. It wiped out the cam, and ruined the lifter bore. Plus, it flooded the oil with particles. The engine had to come out and be rebuilt, and that's the last thing I ever want to do again, pulling this engine out of the car, solo.
My heads are stock LS2 with the trunion upgrade and beehive springs. Going to have a mild Compcams blower camshaft.

I don't build motors for a living.
I'd call a reputable engine builder or BTR.
I have personally owned previous cars with failed lifters.
Plastic cracked and allowed the lifter to turn, snapped PRod, cracked block.

my previous D1SC stroked ls2 setup at ~700whp ran ls7 lifters for over 10k miles without issues. It wasn't a race car but it certainly wasn't built to nancy pants around either. I don't think it was ever rev'd to 7k rpm though, the cam fell off at about 6,500.

Thanks everyone.
Inasmuch as it looks like my new engine is going to set me back almost $10k once I am finished, I decided to use the Lunati Link Bar rollers.
I mean, what's a few additional Benjamins?
