    Cam and pushrod question

    Ok, I've been trying to research this, and i cant get it straight.

    I have an LS1 in my car, and just bought a set of 243 heads and a Z06 cam, both out of an 03 Z06, the guy also threw in the stock pushrods.

    Ok, so the cam is irrelevant, because I'm certain I will be going with a different one.

    I know the base circle of the Z06 cam is different, so the compensate, they made the valves longer, but left the pushrods the same length, 7.4.

    2 questions, are these pushrods worth using, or should i pick up some aftermarket ones? I dont know if these are hardened or whatever.

    2nd, this longer valve stem thing is throwing me off, and i don't know anything about base circle sizes, so I cant figure out what length pushrods I need...or is that going to be one i need to figure out after i pick a cam?

    They kind of inter relate though, if these are good pushrods, then I may use them, and pick my cam based on what size works for that, if not, I'll pick whatever cam I want, and buy the pushrods accordingly

    You have too many variables here. I suggest a pushrod length checker.

    Unless you use 100% of the same stock parts, cam, heads, rockers, pushrods, and head gasket thickness, there is no guarantee it will be the correct length.

    Assemble, measure, and then order some new hardened ones...or reuse the stockers if they measure correct at that point and they are perfectly straight.

    thats my issue, my car is my DD, no time to measure, then wait.

    but i started a thread on tech and got a lot of help. but yeah, the variables are killing me.

    i also got ahold of the guys at TSP, its them ill be ordering most of my stuff through, and theyre gonna set me up

    Unless you go with a huge cam your 7.400" pushrods "should" be close
