Just adding headers gets you up to 480 horsepower.

Above is my original post. I didn't say the DCI heads could not be made to work. But how many stock head Pontiac have a cam like the LS3? High lift short duration.

Few to none I’m sure.

But quite a few have something in the range of a RAIV cam.

Many Pontiac street engines are just like that, and many will buy a bolt on aluminum head that’s reasonably in line with the cost of ported iron heads. The cost to rebuild iron heads properly and then the porting work added to that is within a few hundred dollars of new aluminum heads.

A good number of engines out there right now have the heavy TRW or Sealed Power forgings in them hanging on stock rods or maybe inexpensive forged rods. A new aluminum head that will work with that is what’s going to sell in my opinion.

So whatever Don decides he’s going to market is his choice not mine or anyone else’s, let’s hope he sells a lot of them.
