Stocker camshafts

FINESPLINE · 07-24-2010, 09:20 AM

In the past year I have finished the body and chassis on my 1970 Nova with the intention of making it a legal NHRA stocker. I joined this site to get an idea of what goes on in the class and I have to say that it truly is a wealth of knowledge. I am at the point of decision about the powerplant and the class options it offers. Could anybody offer any insight into camshafts as they seem to be the unknown factor. I have never heard anybody talk specs since the only real spec is the lift limit as per the factory cam. One more thing, the car will definitely be a stick. Anything that you would have to offer would be appreciated. Thanks, John

Let the guys know what combo you are going to use,car falls into a few,and you will get a wealth of knowledge on this site.

John,
Your car can fit into several classes, with several engines and 3-4 years (69,70,71,72, and 68 if no one looks too close

). From a 6 cylinder, to a 2 barrel 307 V8, to an aluminum head 396/375. You really need to pick an engine, transmission, and year for your combination, then pick a guy to either build the engine, or at least supply you with parts and technical assistance, as well as machine work. I could tell you about cams, or send you to the guy who does mine, but if that isn't what the guy you pick to do your work does, it won't help you much.

There are some combinations that you can go with that will be pretty quick, for example a 69/70 350/300 stick, or 69 396/375 iron head stick. There are some quick 69 350/255 automatic cars, and that makes a good stick car as well. The 70 402/375 stick isn't bad, either. It depends a lot on how fast you want to go, and how much you have to spend.

If you plan on running a small block combo i have tried them all and tried over 15 sticks in all different combo's and can get you going in the right direction. p.m. me and let me know what you plan on running and ill give you my .02

350 /250/230 2bbl, M/Stock @3390 lbs.

70 is better than a 69 with a 2bbl. You'll have to dig a little to find out why...

Mark,
Why didn't you just tell him it would have about 10 cc more POP?
Or say it would run better in bad air?

Adger, We don't do Stockers on a silver platter here. LOL . Ya have to learn to find this stuff on your own.

And you make sure you stop that, too.

Thanks guys--you pitch hard and fast and I truly appreciate the help and valuable information you have to offer. Mark wants me to get down on the books and I can understand that and Adger baled me out. It's all good . Ron offers info on sb combos and Alan gave me more choices that I did have to go back to the books. I am leaning towards a 402/375 stick combo but not written in stone because some of the SB combos are interesting. I am not here to nor will I reinvent the wheel but would like to do as much as possible myself rather than write a check for a motor that would be like a black box. I want to know what makes it perform the way it does. Thanks again --talk soon----------John
