Still trying to figure out what length pushrods should i use for a stock TPI 5.7 cam,1.6 roller rockers and cast World sportsman II heads.The pushrods I'm using now are comp cam stock length but they seem to be a little far foward on the valve stem.I dont have a pushrod length checker and was wondering if someone would know the length i need with the parts i have.any help will be appreciated.

what do i need and need to do to measure the length

 

A pushrod length checking tool can be bought at many of the on-line sites, like JEGS and SummitRacing.

From what you described, you have the correct length pushrods already. You can check CompCams' website for diagram on how the roller tip of the rocker arm should look.

Outboard, centered, inboard, centered and outboard is the movement that's recommended.

Hope this helps.

The rods you have should be fine......oriellys has an adjustable pushrod to check the length if you are worried......they also have chromoly hardened pushrods for cheep as well if ur interested.

 

Get an adjustable push rod and check for yourself. They are not very expensive, and you'll know you have the correct size.
