    Do I need to different pushrods

    My mechanic says that my stock pushrods will be fine but I dont trust that assumption. I will be running 222/224 550 112 lsa cam, LT's, Forged pistons and eagle rods, ported heads, 11:1 compression etc. I was gonna get the chromomly pushrods for 100$ but with that cam, do I need a longer rod or will 7.4 work??? -thanks

    um, who is this guy? first too small of a cam, now stock pushrods??? i hope he meant stock length. most after market cams have a smaller base circle. aftermarket heads are usually resurfaced or milled down to gain the combustion chamber size desired. usually this offsets each other. so, technically 7.400 length still works. there's no way to tell for sure without checking.

    If your going forged, rods and pistons with an 11:1 compression ratio I'd go ahead and swap them out. They're a cheap form of security.

    Stock length will probably work fine on a small cam but there is no way to tell untill you get it back together.

    The thing about pushrods is the stiffer they are, the better. You get less bounce so therefore better valve control =better power. I would go with upgraded pushrods, no doubt.

    get 7.4" hardened pushrods. if not the first over-rev you have you will bend the stockers if they (some) arent alreadly bent...
