I have an LQ9 built into a 408 it will have stock 317 heads on it and factory rockers. If it matters the cam is 23x 24x /.62x and .63x. I will have a stock thickness gasket also.

Can anyone tell me what length pushrod I will need or do I have to assemble it then check length?

 

Yep...to do it correctly, you need to assemble...then measure....all of them.

 

Can i buy a measument tool cheap or does someone have one they will rent to me when the time comes? I don't know how much they are.

 

Seems like they are only $20. The pushrods should be in the 7" area. So this will work?
