Sbc pushrod question

J.R. Haddad · 12-15-2014, 06:38 PM

350 Stocker Engine, Hydraulic Roller, Roller Rockers, Lifters have
.050-.060 plunge. Max RPM 6800. Question: Will there be a measureable
difference between 5/16 .080 wall pushrods vs. 3/8 .120 wall
pushrods? I am getting pulled different ways depending on the source.
Thanks in advance guys. J.R.

Can,t go wrong with the heavier pushrods, but if you not run any spring pressure you can likely get buy with the 5/16 80 wall. You mite ck your lift with one then ck it with the other, if it the same run the 5/16.

Denny, Do you feel a custom 5/16 push rod is a adequate for a high rpm SBC Stocker?
(200 / 400 # springs)

Mark, a 5/16 .120 wall would be the least I would use on a SBC stocker engine.
