Just called Comp Cam help line. Wanted to know which push rods to use with 216/220 .525 .532 114 LSA cam. (P/N: 54-414-11) Told me they don't recommend push rods for there cams, have to figure it out on your own. Does not know the base circle its standard. The warehouse is closed for inventory and can't measure. Asked what is standard? The same as the stock LS1 cam, I pretty sure that is wrong.

Does anyone know the base circle and pushrods need? Can use stock but will probably get the sowing machine sound. Want to keep the right geometry for the rockers. Have stock heads, not milled.

Thanks for the help.

Why have a help line if they can't help????? Base circle info shouldn't be that hard or pushrods for that matter.

 

7.40 P-rods. If you have access to a comp catalog they have a valvetrain upgrade kit which states 7.4 prods.
you could reuse your stock ones as this cam is not aggressive enough to really warrant hardened ones.
it's up to you.
