edelbrock performance package

I agree with Stroked340. Though I wonder what are the chances of damaging a head. While he is correct, IF you damage a head.....
I have 2 set of Edelbrock heads myself. I had the coin to drop.
The OE iron head can still do well. Again, your choice.
I would do another OE build if it called for it and would also go no further than a bowl porting myself. Unless there was a reason for it. And I can not see one right now.

Rusty also makes a very good point as well. One that the package is worked out. Though I myself would use a different cam. I like to take advantage of the parts fully when and where ever possible as to maximize the potential of the build. The Edelbrock cam will idle smoother than most others. If you copy Edelbrocks build for what they did to get the power they did, you will know exactly what you have.

There 340 RPM Package is nice. 417HP smoothly delivered.
(I wonder what that does in a 360 built otherwise the same?)

A lot of people fuss a lot over what part and others badger because you didn't use a certain part. Truth is, when your driving, the difference will never be known. Iron headed or not, Holley or Edelbrock carb, this piston or that piston, boxers or tighty-whitey... LOL!
