A quick google search showed them to be universal for various years.

Did you use a push rod length checker to determine your rod length or did you install something that came with a kit? What size were they?

Not sure how you would find the max rpm on these. Did they fit into the lifter trays fine?

Im not worried about pushrod length... I ordered "ls7" lifters from a member on here and this is what I got... they fit the ls2 lifter trays perfect

Dude, not being an ***, but if you don't know what lifters you've installed you damn well better be worried about pushrod length...unless youve already started and not destroyed it.

Well I was told from the guy I bought my trickflow 225's from that I needed a 7.500 pushrod to achieve good lifter preload and since the post above clearly states that these lifters can and are used in ls car and truck engines id ASSUME that a stock headed ls engine that required 7.400 pushrods that I would be fine with my 7.500 pushrods since the deck of my trickflow heads is thicker... Hence me only asking if they will be good for 7k rpm instead of what pushrod do I need

Yeap... These are stock replacement lifters and not ls7's which have a different bleed down rate apparently...

There are only a couple of lifter manufacturers (Eaton, etc.) but not sure who makes the ones in your hand.

Yes, and I was told by the company that I bought my cam package from that I needed a 7.425 push rod. I actually measured and needed a 7.350 push rod. Had I just installed what someone 'told' me to I would be in your boat.....trying to figure out what's wrong with what I've already installed. Oh, and then when people tried to help me I would tell them that I have measured nothing but they must be wrong because the person that sold me these parts that I don't understand or trust told me something else.

Someone please explain this to me? Oh, and while someone is explaining this to me the OP should go out and buy a $22 push rod length checker to ensure that he doesn't destroy his $3K engine with $100 lifters that he knows nothing about.
