Thanks for the info. I talked to my buddy and he told me that's the same cam he has in his engine right now with fuelie heads on it and he's pulling 12's in the 1/4 with his chevelle. Grant it, I want this car for more of a steet car than a strip car, so I'm kinda concerned that he might be traveling down a different route than what I had planned. We were talking about heads, and he suggested getting aluminum heads. Like I said earlier, I don't know all the ins and outs of engine building, but how much difference are the Brodix IK200 or Dart Pro 1's going to be in comparison to the cast World Product Sportsman 2's? I mean is there going to be a large difference between aluminum and cast, or between the different manufactures that I'd be able to notice on the street? Once again, thanks for all the adviceLast edited by 67CamaroProject; 07-07-2006 at 12:59 AM.

Basically, aluminum transports heat out of your engine faster than iron will. If you're running high RPMs constantly then that's OK, but if you keep in the lower REVs, as you will be most of the time in a street car, then you need the heat to expand the gas in the cylinder, after all, that's where your power comes from. I would go with Dart or World Product Sportsman Aluminum heads. They're quite cheap and as good as you will ever need on the street. Apart from the fact that alum heads can kill low end and are much more expensive aluminum and iron have different heat-expansion rates, so your choice of head gaskets, head torqueing and cooling issues will become more critical. And a 3000 stall converter will shake your bones at every stop light
I'd go for a smaller one personally in a street car. For the strip 3000 or higher is OK, but if your cam comes in at 2500 and the converter at 3000 you'll need new tyres every other month. I would also go for a slightly smaller cam, a cam that big in a street car will get you some wear problems before long
As always, that's just my opinion...
Hope I could help,
