SBC Chevy Nitro Rockers 7/16 Stud 1.50 ratio

The Car Shop started carrying these not too long ago when we were having trouble finding a good source. Good service and a great price.

Joe, I have been taking an interest in following your car for sometime. As a Nova owner, a frequent visitor to StevesNovaSite and a member of SoCal Novas you understand my love of these ole ecomony cars.

Many years along, I had a 283 that I tortured for years but it was just in the wrong car but, it sure was fun to race and drive.

I would like to like to pick you brain from time to time about getting into racing in stock eliminator.

I noted in this thread that the stamped rocker arms were of the 1.5 flavor. Is 1.5 the only type you can use or is the 1.6 or even 1.7, if there is in the stamp steel, an option under current NHRA rules for a SBC.

Not sure what the ruling is on rocker arm ratio,,,but some of the old timers might remember the story about Bill Jenkins using Ford 289 rocker arms on his A/S 66' Chevy II(327 4speed) back in the day against Jere Stahl's A/S 66 Hemi Plymouth. He was thinking outside the box, as usual. Danny Durham

That may be a myth. The rules that year allowed those cars to use any aftermarket flat tappet camshaft and valve train. When I saw his car race at Tulsa that year, he had roller rocker arms.

Any ruling on the ratio? I have an article written in Oct 1966 "What Makes Bill Jenkins' Chevy Run" He ran a Isky 550 flat tappet cam with a 108 centerline and Crane roller-tip rockers. Not real stock for a stock class but I guess those were the rules.

Jeff Lee · 05-05-2010, 12:30 PM

You can run any ratio as all that is checked is lift as measured at the valve.

Eddies66 · 05-05-2010, 04:44 PM

Jeff, thank you for the information. I was reading an article about a gent with a 409 that found a Canadian source for stamped steel rockers that were 1.7. It was a simple question and all I need was a straight answer. I guess it's an Arizona thing about looking a man in the eye and getting a straight answer.

Im not sure you understand what Jeff is telling you, the cam still has to check at legal lift specs so theres no advantage with the higher lift rockers. Maybe Im misunderstanding him too, who knows.
