Re: roller rockers
I would have rather had roller lifters to match my cam. Maybe next Christmas.

Re: roller rockers
Darnit Kyle, you know if I had NOS I would run it in Super Gas where the DP's and CJ's should be.

Re: roller rockers
Super Gas? How would you slow them down that much?

Re: roller rockers
Guess I'm a dumb-*** but why would the exact rocker ratio matter to NHRA tech? The lift at the valve would seem to be the important spec, so measure at the retainer and if it is in spec, it is good. The amount of machining needed to use a significantly different ratio rocker on a particular engine to maintain the geometry and have pushrod clearance is probably illegal anyway.
Anyone who has measured the OEM rockers know the last thing they have is an accurate ratio. Measure 16 of them and your probably going to get 16 different numbers. It's sort of like the rod/piston/pin issue a while back. The total weight of the assembly is the guide so you can have a little lighter piston with a little heavier pin or rod, etc, as long as the total weight is good, it's OK.
