So i'm in the process of building my engine its a 880 vortec block .040 5.7 rod 3.480 stroke i have dart iron eagle heads/scorpion roller rockers 1.6 int 1.5 exh cam is comp thumper Duration at 050 inch Lift 235 int 249 exh
I'm looking for a good set of roller lifters but only have around $250 to spend
was told morel ls 5315 lifters would be good?
Was your vortec block set up for rollers? machined flat on top off lifter bores and 3 nubs sticking up at the 3 center cam bearing bosses?????
yes it was factory roller
Joe Sherman (world class engine builder) says it doesn't matter, that he has used everybody's lifter and they all work. I like Howards #91113.

To me it matters i hear a lot of bad reviews about some lifters, i don't need to have one fail and wipe my motor out.
The bad reviews are likely Chinesium junk. Get OE rollers from a reputable firm like Howards (who has been in the cam and lifter business since Noah was a teenager) and you'll be fine. You get what you pay for.

I have a good friend that is a serious drag racer. He uses SBC roller blocks and buys all that come up. He knows what he is looking for and buys all that he considers worth while. He uses stock high performance Chevy lifters. He runs them for a season and changes them out for new. He has never had a failure. They are a fraction of the cost of Comps or others. I'll try to get him to join and share his knowledge on this topic.
For a street engine, OE should be fine. If you are going to punish it so it sees 6500 rpm shifts a lot, Morels are you best bet.
