It ended up bending a pushrod and breaking the adjacent rocker arm at the last race this year. So it's time for an upgrade.

Originally I was thinking of the chromoly comp rockers but the max spring diameter is much less than Harland Sharps. I'm open to anyones thoughts or suggestions.


I would look into the rockers Mancini is selling. Made by Harland Sharp, lifetime warranty, under 500 bucks.
Buddy runs the small block versions of them on his trick flow heads and really likes them. Great bang for the buck

Thats interesting...wonder what the difference is? The adjusters? Actual Harland Sharps are nearly double the cost...
