Guys,

I've read a lot of info on the LS7 lifters....however I have not found a thread that settles the debate as to if they are a stock replacement for an LT1.

Did anyone do a comparison of the lifters? Anyone using them with stock pushrods?

 

I'm using them although i am no longer stock. My pushrods are still 7.20.

 

No debate, i've got a couple lt1 and gen 1 sbc engines assembled with them with over 200k miles combined. Stock pushrods will work in a stock engine.

 

ive got them in my cc306d car... stock length chromemoly pushrods stock heads/gaskets... my valvetrain has never been quieter

 

What he said.

 

any pictures of where the rockers are sitting on the pushrod?
i saw 1 thread where it looked like they didnt quite line up correctly...

 

I got a mixture of the ls7 and the stock lifters, to explain my spider assembly took a dump on me, seems to work fine, Art

 

i am using ls7 lifters with 1.6rr's and 7.200 push rods with no problems...

 

They dropped right into my engine and worked fine with 7.200 pushrods.

 

Does anyone know if the LS7 lifter part number has superseded the LT1 part number?

 

There are two LT1 lifter part numbers and they are still good. So, no, they have not been superceded.
