Default MS3 question?

Does anyone know if the MS3 cam is ground on a smaller base circle? Im trying to figure out what pushrod length I need to go with. Some people have told me longer and others have told me shorter.

If you are using stock heads, I think you can run stock length. 7.4 If you are that worried about it tho just get a pushrod checker.

Yep, I am running stock heads, but Ive heard you need a different pushrod length to keep the lifter pre-load correct.

No, stock size is fine. I have been running stock size since i did my ms3 swap a year ago. Some people go one size up but in alot of cases it has shown to be bleeding off compression.
