Looking to upgrade lifters from Comp to BAM. I was told BAM lifters need bushings. I run an Indy block with no bushings. I'm just trying to see what some of yall have done to upgrade. I currently run cup pushrods , do they make a cup with oil hole? Or do you got to convert to ball and ball and change adjusters
Thanks. How is your Indy block oiling the lifters???

I was told BAM lifters need bushings Who told you and what is their reasoning ?? You can get ball/cup oil-through pushrods - quite common.

Consider reading the post on rocker arm geometry before investing in cup type pushrods. There is a reason Jesel only uses ball and ball pushrods. I gather from B3 racings article it gets more critical as the performance level rises.

I got the BAM lifters in yesterday. They look decent. I need to get it mocked up and check pushrod length. Let us know how much different the lifter pushrod seat height is from the Comp lifters. My notes say the Comp 892 (pushrod oiling, not 829) have a seat height of 1.91", and the BAM 1.93". But I don't know if the companies measure it the same way. Comp defines seat height as top of a 5/16" ball in the pushrod seat. I have Comp 892 lifters and this picture shows what I measured. And it agrees with Comp's definition.

I don't have a bunch of lift in it. About .650 lift I got the BAM lifters in yesterday. They look decent. I need to get it mocked up and check pushrod length. Get those ordered and see if it will work. I'll probably be the only guy oiling both ways lmfao
Can't wait to launch it again on my 512 I have stock & pushrod oiling, SO you are not alone lol

FWIW you can get away with pretty small restrictors especially using both oiling methods Id think. I have .029" at the lifters the last few engines with no ill affects.
