Anyone install Edlebrock aluminum heads ?

Back to the OP's question.
Will bolting these out of the box Edelbrock RPM heads add any power over the stock Iron ones? The answer is in a nutshell, yes. But with zero other mods the power gains will not be there as much. So for just $2500, is it the best bang for the bucks? IMHO NO. The OP does not know what is inside as far as pistons or cam. These MUST be found out before throwing cash at it. I think he will be disappointed when his 8.2:1 360 runs like a dog with these big heads with no cylinder pressure.

These Mopar forums are a good place to separate the Bench Racers. You all offer some good advice with many different opinions on how it will work. But you can not make someone follow this information if they keep listening to their bench racer friends.

The Cam may be the heart of the engine but the heads are its throat and arse hole. It should be designed as a team and not as a "One item" fix.
