Best choice rocker arms
So, the season ended with a bad noise from the rear engine and I have now pulled both engines and started the search for the noise… first thing i found out was that one of the Jesel mohawk rockers had snapped right off. So now it’s time for new rockers and wonder if someone of you racers have input in which one to pick?
I have looked at the Jesel pro steel rockers. Are they a good pick?
the engines are from the beginning chief race engines dart big m 615cui, dart pro1 320cc heads, titanium valves, Jesel cam drive, Jesel lifters, 14-71 tbs blowers with coolers, dry sumped, and all the bells and whistles that comes with it.

We have a similar combo and have broken a few rockers call jesel they are awesome to work with, i also learned the adjuster can be no more than one or 2 turns down they were very firm on that and we had to get longer push rods if you send them all back they will rebuild them check them for cracks and reshot blast them its way worth the money!

Changing to steel
So, nobody think it’s a good idea to change to Jesel pro steel?
in my 55 Chevy I have solid jesel rockers and they seems stronger then the mohawk style by the looks.

those are what i used on my 540. it was about the only thing i didnt break. the way the arm is configured seems way stronger. i would be willing to bet the way yours broke had to have some kind of flaw in casting or the manufacturing process

FYI in a past boosted engine I ran stainless with no issues.
