No trick set ups and must maintain OEM rocker ratios only. No under cut cam lobes with non OEM rocker ratios. No Jomar type girdles at all. Last edited by X-TECH MAN; 11-06-2011 at 03:39 PM. |

Re: Roller Rockers in Stock
Greg... BBC standard BBC 1.7 ratio ( factory W block is 1.75... but there's nothing in that ratio that handles this abuse ! ). Let's me use the BBC 7/16" stud. Cam has net lift at the valve, of .496" -.500". It all works.
Also, Crane has always had their P/N 15750 gold aluminum rocker for the W engine ( 3/8" stud )... it too, is 1.7 ratio.

Re: Roller Rockers in Stock
The manufacturers want to see their NEW cars win National events. They dont give a "Flying you know what" about the old cars. I hope Charlie is wrong or pulling everyones leg but NHRA has pulled this stunt before in 1972 and got away with it.

Re: Roller Rockers in Stock
Kind of makes you wonder, if the new COPO comes with roller rockers already? This possibly being the reason for the suggested rule change? Wouldn't that be a nit in the soup for the CJ and DP bashers, lol.

Interesting letter to the Editor that was in a 1970 Dragster that I bought at a swap meet today.
