WHAT IS THE FACTORY RATIO ROCKERS ON THE ROLLER 5.0

I'VE BEEN TOLD 1.45 TO 1.6

PATRIOT PERF. SAID 1.45 WERE STOCK BUT I'VE HEARD 1.6 WAS STOCK

WHAT IS CORRECT?

REASON I'M WONDERING IS I HAVE AN F303 CAM WITH 512 LIFT

IF THE 1.45 IS CORRECT WHEN I GO TO THE NEW 1.6 I COULD HAVE A PROBLEM

BUT IF THE 1.6 IS FACTORY THEN NO ISSUE

1.6. That's what the stock ratio is.

But with stock stamped rockers the ration can be anywhere from 1.4 to 1.6 due to tolerences in manufacturing and wear.

I think 1.45's are sbc ratios.

Wow seriously? I never thought it was that much of a variance.


An old trick is if you can find rockers off of a 460, they're 1.72, but i don't know for sure if they'll work on the newer style pedistal mount heads or not or if that was an old trick on the old stud mount heads.
