The Alamask had no affect on the tune.
The nitro sure did though.

Re: Offy?

Bill, that was probably Bobby Meeks; famous for nitromethane V-8 60's in midgets. Used some type of oil additive that smelled like shoe polish to hide the nitro odor. Meeks was probably the first to use that additive except it was used in the fuel. It was later named "Alamask". Extremely concentrat...

Re: WTB, Roller cams

Hi Mike, Not exactly what you want but I thought I would mention it. I have a steel billet for a 430 Ford with a Schnieder 32R (roller) grind on it. It only has .316 lift but could be reground to something modern. It has old cosmoline on it and a few very small rust pits, the type of which would cle...

Re: Cam advice for a mild 327

If you ask your question to 6 different guys, including me, you will get 10 different answers.
Why not ask the guy that runs this forum?? He is as good as any around and it would help support the forum.

Re: Why no Ardun hemi head SBC conversion?

I talked to Isky and he said he dropped development of those heads because of not enough interest to afford to develop them.
He doesn't know where any of them are now.

Re: Why no Ardun hemi head SBC conversion?

As a bit of trivia, In the 60's Ed iskenderian made several sets of single cam (per head) desmodromic heads for the SBC. They were very successful in tests. He advertised them in several magazines for a brief period but apparently the market was not ready for them so he didn't persue it. That would ...

I would agree normally but I only have data on large flatheads, 315 ci or more. Nowdays 321. It works.

Re: Evolving the Side valve flat head design idea

I often wonder why H-D when they had an almost unlimited development budget, didn't think about bigger ports and valves. While bigger is sometimes slower flow with N/A, on a flathead Ford it means more hp if the volume goes up. We did flow testing back in the late 50's with ports enlarged by welding...

Re: Question about modern technology cam for Early FordFlat Head

I know about the NOS French flatheads but still.. pdq67 There's a US company that makes blocks. Edelbrock and Offenhauser make heads. You can buy every part, brand new, made in America Most vintage racing associations will not allow after market or French blocks. Mods to an OEM block are unlimited ...

Re: Spintron

In 1956 when we were developing the Allison race cams we set up a head with one cylinder’s valve assembly in it with a variable speed motor to drive the cam. We ran it up to operating rpm range and stopped motion with a strobe-o-tach. We then photographed the assembly with a macro lens equipped came...
