Cam & Head Choice

I'm going to start on puting together the rotating assembly this weekend and I need some advice on the combo of heads,intake and cam.The engine is a 383 that's going to come in at around 9.7 and going in to my 70 El Camino.I was planing to use 12558060 vortec heads with a Weiand 8121 intake,3310 Holley 750,GM HEI Ignition and 1/58 headers.I was wanting to use a Howards cam 180315-10 .462 .470 lift 210-215 @50.I saw this combo at ATK engines.I would to hear your opinons.Thanks

Sounds good. You could go with a slightly bigger cam and beehive springs... but that means a few more $$. Depends on what you're using the ElCamino for.

Me too

I'm also building a 383. I was thinking of running 10.1 with about 230/236 @ .050. I have tfs g-2 heads and a 3,000 stall. When calling for cam recomendations they sure push to run around 240 plus @ .050. Im thinking maybe comp xe282hr for mine though, hope its enough cam

The El Camino is just a street car,I wanted to keep things more on the side of torque.All we have in California is 91 octane so I don't know how much more cam I cam run.
Thanks for the comments

Mines street also. With 9.7-1 you can run 91. If your cc are polished and if the heads are aluminum you could even run 10-10.5 on 91

Remember big cubes like a 383 swallow small duration cams. Your combo should have plenty of torque

as i'm sure you already know these are the aftermarket GMPP vortec heads but they still need to stay under .475" lift unless you have had them machined to handle more. i would mention more cam but with the heads you have, the cam you have chosen is about the max you can go with

You don't need to machine vortec heads, spring swap is all you need to .500 inch or so. http://www.carcraft.com/techarticles...ade/index.html (this computer isn't letting me hyper link)
I've got a 383 short block in my garage with the xe282 cam also

Thanks again for all the great posts.I should have mentioned I'm using a roller block.
Yes knew the lift limitations on the stock vortec heads so your on to me why I'm looking at that cam.
I didn't know about the comp cam spring set up so that is something to look into.Like everybody I'm
on budget but I want the best performance I can get for my money and the best advice from you guys.
I've been looking a couple of other cams and another head for your consideration.Two Comp Cams
one I might be able to use with the stock vortec head the other might need one different springs.

The head I was looking at is from Scoggin Dickey

If anyone is familiar with these heads please let me know.

All you fellows should pay attention to this article and note that a high-rise intake was used to make the most power. An Edelbrock RPM or Weiand Stealth makes more power on any street/strip SBC or BBC than any other manifold I have tried on the DynoSim builds. And now here is hard proof from a hard dyno that the taller intake works best. The standard Performer and other short runner, low-rise intakes are little more than aluminum, low-weight OEM manifold knock-offs and are pretty much worthless from a real power-making standpoint.
