CAn you install LS1 roller lifters into a 1995 lt1 engine with out any plms. and will all fit as stock?
also what are the advantages in doing so? Thanks Guys??

 

They are different

 

Most places sell replacement LS1 and LT1 lifters as the same, from what I have seen.

 

they look identical to me. I bought some LT1 used lifters to modify to make solids for mockup/clearance testing and whatnot, and they look identical.

 

the lifters are the same, the plates are different, but the lifters themselves are the same

 

They are the same, I'm running a set of the gm race lifters in my car.

 

What do you mean the paltes are different?? For what I`m getting here they are the same dia. and height both being OEM so they should be a direct fit??

Thanks

 

the plates that hold them in place in the block, not any part of the lifters, the lifters are the same

 

One of the few things to carry over to Gen III was the lifter diameter.

That still surprises me that they didn't increase the diameter.

 

even the current gen 1 crate engines use the newer design LS1 lifters

 

DAve89IROC,
How are the p[lates different, Where could I see some pictures of them, and if the lifters are all the same so then should not the LS1 lifters be able to be held in with the stock LT1 plates then, or do ya mean just that the LS1 plates are better quality for some reason, But either plates will work to hold them in Correct??

 

the lifters are the same. just reuse your lifter spider (retainer). the LS1's use a totally diff. way of keeping the lifter in place and not rotating. dont worry about it. scoggin dickey has great deals on LS7 lifters Ive hears, also there's a perf. lifter thats made for the cadilac cts-v. not sure which ones the best price though.

 

I was surprised at that too. Probably has to do with production machinery - like the 4.40" bore center which also carried over.
