Small block + 4 speed build

I’d upgrade the pushrods. Don’t worry about the weight, you can’t beat a beefy strong pushrod.
I’m not worried about weight, I’m using 7/16 .120 wall pushrods in my own engine. Heavy pushrod is a good thing.
I don’t have pushrods for this yet as I don’t know the length I need yet, but I was planning on getting some hardened .080” wall 5/16 pushrods in this…
