Well, it turns out I need 6.325" pushrods. I have yet to find some so far, but I'm still looking...

I think Alex's Parts sells them in that length. I've been browsing their site for a bit now while planning out my GT40P build.

I just bought these for my 331 stroker with GT40 heads and stock rockers. https://www.alexsparts.com/6-350-har...-hyd-roller-1/


Best price I could find for the length and quality. I also bought the rocker fulcrum shim kit. I set each rocker up individually. I had to add shims to 12 of the 16 rockers IIRC. Solved all my problems quick and easily. Good Luck!

NICE, thanks! I was hoping i didn't have to go custom order. I see there are 6.320 and 6.350, but not 6.325. I'm guessing we'll want to go with 6.350" because yes, that will add .025" of lifter preload, but that's well within the .020 - .080" spec.

Bought the 6.350 from Alex's. Although I found out after the fact pushrods.net offers a super-quick turnaround time. Good to know.

I'd get the one piece push rods, I broke the top ball off two of those push rods somehow. They didn't bend at all. but broke that ball off.

Too late...

They'll be fine, just don't zing it to 15 grand like I did a few times. My T5 had a bad shift fork, blocker ring, or something...still not sure, but it went from 3rd to 2nd at the 1000ft mark on the track. I'm still surprised that's all that broke.

Haha, I'll try not to.
