OER Lifters need adjustable rockers. If you put LS7s in there you don't need adjustable rockers.

I used LS7 Lifters with an XP cam and it ended up needing 6.95 pushrods. Dont know if it was the lifters or the cam or what. I dont think most people have to change pushrod length with XP cams so It leads me to believe it was the ls7 lifters.

Thanks for the reply guys, but how do I find out what lifters it has on there as of now? It has the yella terra rockers witch from what I know are not adjustable. So is it safe to say I can just buy the ls7 or stock ones and replace them all?

I just don't want to get too involved in this project just yet, just get it up and running fine, get the tints done, do my 04 seat swap and see if it is driveable like that if not xpz time for when Paul from PRJ gets here to tune it for me on e85

Considering this has never "ran fine" for you, I wouldnt assume stuff like this was done correctly. In general, you are going to UPGRADE power and relibility when going to a stock rocker and stock lifters.

But if it did run fine, the yella terra rockers would obviously give the better power correct? Since you are goin by it not running fine?
