Default Needs some help with lifters.

Ok so I'm putting in a new cam I have new pushrods and new springs. I just realized that I spaces on getting new lifters. I have been told that ls7 lifters would work on my block. That they are the same dimensions as my stock lt1 lifters. Is that true. If not what should I get

They are basically OEM replacements now. I'm running them on the 383 build I'm doing. Ran them on the LE2 set up as well. Best bang for the buck. So yes, they will work.

Tons of guys are running them on here. Nice lifters for the $$. GMPARTSDIRECT had the best price around when I was in the market for them.

Someone correct me if I'm wrong, but I believe they withstand higher RPM's??? I think that's the rumor anyhow..I don't remember off hand.

Not to rain on anybody's parade, but... Wasn't there some discussion a while back, saying that the pushrod seat in the LS7 lifter was a tad lower in the body than the LT1, LS1 lifter, therefore even though the outer dimensions were the same, the LS7 lifter could require a longer pushrod to maintain proper geometry?

That is correct. Measure to be sure.

Definitely a valid statement. Some have said that the cup is up to .100" deeper into the lifter body. Just to be safe, I would measure.

It's best is to measure just in case. In my case the pushrod cup was not any different than my original lifters.

+1 on the LS7 lifters working without a problem. As a matter of fact, if you want to get new hydraulic roller lifters for any SBC (including LT1's) from the dealer, they will give you LS7 lifters.
+1 on measuring for peace of mind.

When will you be finished? Did you go with the CC503 like I told you to?
