Re: Lifter rule in Stock
NHRA tech department clarifies recent lifter rule change
The change is to allow the use of a solid lifter in place of a hydraulic; you may not replace a flat tappet with a roller. So what effect if any would there be on a 1993 build chrysler hydraulic lifter on a 383 big block. I assume new valve springs would be needed. Didn't change the rockers, still original as delivered. Thanks Eric
