Also known as the Duntov grind. Gee, it's hell to get old. As in, "Don't run him man, he's got a Duntov cam in there."

When I was young a very good friend of mine ran 63 version in his new 65 Chevelle 327 and added 2 4's. That thing would fly. That was back before that S E Asian thing broke up the old crew. I wonder where the heck Gary is anymore.

3836151, I think, was the # for the Duntov hydraulic lifter cam. 350 horse 327. Had one or two.
I think the "full race" cams came first, then guys wanted something a bit tamer for the street, so the grinders made 1/2 and 3/4 cams for them. Back then nobody knew (or cared!) what "degrees" meant, so they had to call 'em something.

Then you had the" Off road cams."......

Nothing ever sounded better. It was like saying "potato-potato-potato-potato" fast with the accompanying clicking. Music to my ears in my youth....the stuff of dreams.

I always felt the 3/4 race term was just used to describe a cam more street suitable than a full race cam.....it was milder, less radical. As was mentioned a lot of what came out of our mouths was gibberish designed to impress our equally naive buddies. Back then no one ran a "Chevy" engine, it was always a "Corvette" engine. ("Yeah, I swapped a Corvette engine into my rod." ) That always impressed everybody, especially if you went down and spent the $ 17.99 to buy some Vette valve covers. Also, the girls dug it. I sincerely doubt that many actual Corvettes were stripped for their engines.

It's kinda like the old saying............."the older I get, the better lover I was."

I've still have an Isky 30/30 in the garage.

It was in the 400 I had in a '62 pickup. The 400 is also in the garage torn down because of a busted valve spring. I was going to rebuild it and put it in the Mustang, but I've decided against that idea. Someday maybe I'll find an old truck or something to put the 400 in along with the Isky and 2 fours. BTW, the Isky was in the 265 that was in the '36 coupe when I bought it but the engine had spun a rod and we short blocked it out. I didn't know about the cam until I went home for my 20th high school reunion in '81 and my step father had it in his shed. I'm not going to try and rotate the earth, but I think it will make for a good cruising engine.
