My LQ9 had .130" preload from the factory. Even with an Comp Cam I had .100" preload with 7.375 pushrods. You just never know. There is no better procedure than to just measure. It is not always convenient, but always accurate.

i have a buddy who has one of the measuring things... i dont know a whole lot about it or the preload or anything. i guess i will have to figure it out once i get it together then i will just have to get someone to overnight me some pushrods cuz im gunna want to drive it haha
Shorter than 7.375. 7.350 would be a better length to start out with imo.

I would definately recommend measuring the length out with a length checker. It takes all the guess work out of doing something like this. The setup you are running has too many changes to it to estimate where the length should be.

Ditto to all on the measuring, I am going through the same thing as we speak. Test the wipe pattern with your adj. pushrod at the intended length (zero-lash + intended preload) - in my case I will need to use shims.
