Does the rule means that cars such as the Ford small blocks, Oldsmobile and Buick engines can runs guide plates? The interesting part of this rule is that for many years, many cars have been running larger pushrods. Prior to this rule change, there has never been a published specific pushrod diameter available.

I am a "newby" to stock eliminator racing, but when I was building my motor, it would have been a lot easier and cheaper if I had been able to use roller rockers. It wasn't all that expensive for me to buy rocker arms, and adjustable push rods for my Olds, but I know the big block Chevrolet guys spend a small fortune on yours. Though I'm sure all the purists here have a point as well when they say that using roller rockers is getting away from stock racing.

I know a lot of you guys get killed by the stock rocker rule. We have it pretty easy as the 3800 has roller rockers from the factory.
