Replace rocker shafts for sure

mini said

So I just contacted t&d about shafts. $158 each shaft. They are a 3/4 shaft and tell me they do not offer a bushing in place of the rollers.

B3 says it definitely needs some geometry work so I am getting him the specs he requested for that.

Both said definitely an oiling issue with the previous combo. I was planning to tare down my newly built short lock again anyways so I might as well do it right the first time and do oiling mods to send more oil uptop ect.

The hold downs are 7/8s with a thin shim down to the 3/4 shafts. The hold downs also have a sleeve on the shaft. Weird setup

I should have been a skosh more detailed. T&D will install bushings in the rocker, but they won’t retro fit bushings.

And like I said, you have to ***** pretty hard to get them to do bushings, because like everybody else, they have a hard on that needles are better than bushings. I say they ain’t, and if I’m writing the checks, I get bushings.

Any decent engineering books will tell you NOT to use needle bearings on a reciprocating shaft. Yet, because Chevrolet was so damn cheap and used the GARBAGE ball/stud system that even needle bearings on a reciprocating shaft is better than that junk system.
