Can anyone identify which block these lifters fit. They were supposed to be for an ls but the bore spacing is wrong. Seems like I ran across a thread similar to what I'm seeing but can't find it. Anyhow here's a couple pics of the morels next to the stockers...

 

do you have the box they came in? part number on box maybe?

 

Maybe you can change the link bar on these lifters? Many of the solid lifters I have used from various companies can be changed just so long as the attachment screw has proper height clearance from the lifter boss.

But a part number would indeed be helpful.

 

They didn't come with a part #. Think we got it lined out between Straub and Mike Lewis it appears it was just an honest mistake and they are standard sbc lifters. Gonna get em shipped back today. Thanks for the input...

 

Those fit a SBC only. Some get confused as the LS1 takes the same lifter as the late model chevy but NOT the tie bar type, only the drop ins.

 

Yes and thanks for your help chris. Truck picked up .5 sec and 4mph in the 1/4 with no other changes than the lifters. Still not quite where it should be but getting there.

 

Good deal. Yeah I love it when I hear the words "the morels are heavy". Who gives a darn on that side of the fulcrum when you can change lifters and make more power and go more rpm. Might be a little more expensive but they are worth the money.
