Does anybody think that shorter rods might be better than long ones on a short track. My dad wants to build a 350 with 400 rods and 327 pistons.
He was thinking that the short rods would accelerate faster.I think it's a bad idea myself. The weight that's lost in the rod would be gained back in the piston and you would lose the leverage of the longer 5.7 rod
Any opinions?

Stick with the 5.7 rods or if rules permit go to longer 6'rod

berger is 100% correct ! There are many reasons that you will need a long rod ! But the most important reasons are rod/stroke ratio , cylinder fill , and dwell time at TDC . With that short of a rod , your rod/stroke ratio would be terrible !!!! You would just end up hurting yourself all the way around .

I told him if I had a 400 I would put 5.7 rods in it.I don't know what Chevy was thinking using that short rod anyway.Besides 400 rods are harder to find and 327 pistons are higher priced than 350s.Maybe if he sees this he will change his mind. Thanks
