Hi,

I spaced and sent this to a list member when I meant to send to the whil 
list. The question came up about "which issue of CMS", I I forget, but 
most likely a late 2010 or early 2011 edition.

l8r,
rml

Hi,

I might also point out that Classic Motorsports ran a great article on the 
various aspects of roller rockers. Lots of details and some dyno pulls to back 
up the conclusions. Def. worth the read.

I have them on my TR6 autocrosser (1.5:1) and the geometry seems to be correct 
and I have no odd issues.  I just took my time and measured / observed 
everything and I've had no issues. FWIW, I'm running a Isky Z19 cam with 
.410-ish lift.

Failure points in my past have been broken rockers (stock) and broken pedestals 
(stock). But the tubular pushrods and pedestals from Goodparts are ROCK SOLID 
and the H/S roller rockers (from Ted) work perfectly even after some wierd 
"cock-ups" on my part - like the time I left the adjuster screw loose and the 
pushrod popped out. That mishap dinged the rocker, but no craks or drama. I 
didn't even mess a session.

regards,
rml
