CAT rocker arms

[GAZ440]

Hi guys, my first tech question on here.
I just brought a set of CAT 1:7 roller rockers for my 440 of evil bay. On one of the Auaaie mopar forums I visit, there was a thread bagging these.
Have you guys had any problems with these brand rockers?
Cheers.

I personally wouldnt run any CAT products. I use predominantly Crane stuff when I'm using them. The reported issues are the ratios being off, the adjusters not threaded properly, the hole for the adjuster not drilled on the correct angle (so the pushrod angles are off), and flat out breakage under heavy use. With 1.7s, i would be particularly aware of that last one...The others you can catch during installation and rocker geometry setup.

I have seen three motors with broken CAT rods. One motor it happened to twice. The engine builder no longer uses CAT rods or anything else for that matter.
