Mopar Indy 440-1 heads breaking rockers

[Myron Piatek]

X2 on Harland Sharps. I ran them years ago on a W-2 head 360 and literally put thousands of runs on them bracket racing 2, sometimes 3, days a week. I ran a big solid cam, no rollers, but they took a lot of abuse. I have a standard set on my IHRA Stocker now, which actually has more spring pressure than my bracket motor did! I have the caged rollers. I believe they had actual needle bearing when they first came out. They also have the aluminum body on the shaft with no rollers for some budget applications.

Indy rocker have a short life if you get a few hundred runs out off them you are doing good .. they always break off at the adjuster when their life span is over...Indy sell a lot off rocker arms and now you know why ..buy a set of harland sharp and you will be much happier
