Pushrod recommendation...
Can anyone recommend a decent set of pushrods for use with a factory roller cam setup? I'm unsure what length or diameter the factory used..

Re: Pushrod recommendation...
If you did search and cant find it, then please post that you searched. People will be more likely to help.
Roller cam engines came with 7.200" long, 5/16" diameter, .080" wall thickness pushrods. Stock replacement mild steel Manley pushrods would be part number 25717-16. High performance hardened chrome-moly Manley pushrods for use with guideplates would be 25733-16.

Re: Pushrod recommendation...
im 99.5 percent sure they are 7.200 if everything is pretty much stock in the valvetrain. i even think if you have a summit or jegs catalog it lists the lenghths of the pushrods for an 87 up oe roller setup

Re: Pushrod recommendation...
Get a $12 pushrod length checker, and a sharpie, and double check the length needed. You'll use the tool again later.
Then yea, get the chro-moly ones.

Re: Pushrod recommendation...
You can use either part number I listed with guide plates, they're both hardened.
