Hello all. I'm wondering what are the best shafts to use for isky ductile iron rocker arms.
Hardened?
Chrome?
Stock stamped shafts?
Cam is relatively mild. 520ish.
Thanks

Hard chrome shafts from RAS are the best IMO. They are thick wall and have a nice hard chrome treatment like a rod on a hydraulic ram. Gus

Hemis were the only motors with iron rockers that got bushings.
Buy a quality steel shaft and you'll do just fine. I think that the M.W and 340 T/A motors came with bushed ductile iron rockers also Maybe not You couldn't use a ductile iron rocker on a stock stamp steel rocker arm shaft, they would gall up and ruined the rockers after a while, been there done that, Made that mistake twice

You couldn't use a ductile iron rocker on a stock stamp steel rocker arm shaft, they would gall up and ruined the rockers after a while, been there done that I had two motors, one with Iskys and the other with Cranes. Both with stock shafts and tons of street miles with ZERO problems. Pretty sure only the hemi rockers were bushed. Anyway, its a moot point since we're all advising a decent aftermarket shaft. My main point was that hard chrome is not a necessity in this case.

I called RAS yesterday. He's waiting on shafts right now. I'm going to send the whole shooting match to him over the winter.
On a side note, how are you guys making the banana grooves? Free hand with a die grinder?

I know the ras shafts are grooved.
I'm looking to groove some production shafts to get me by.

Yeah, that's what I did..but I went with a straight cut, as opposed to the angled one (I can't imagine how you'd do an angled cut free-hand like that on a round surface)...haven't run the new setup yet (Crane ductile iron 1.6 ratio) so can't comment on whether that home-made bannana groving job worked or not.
