Actually it's more like 120-130 rwhp over a bone stock gt! I would have to agree this is pretty amazing considering what we've been used to!

4500 rpms to about 6500 is looks like is HUGE.

Granted this is already with an aftermarket probably custom grind cam, but still.

Like mentioned before, with a 'custom to this head' set up, there's certainly gotta be more on the table.

Having said that though, I still think it's going to be more cost effective for 90% of 'daily driver' Mustang owners who modify to go with existing ported PI heads. And I think it'll remain that way for quite sometime, if not forever.

Looks like i know what the wifes' mustang's getting next, lol. (Weather she wants it or not)

Those numbers are bad ass considering they are only $500 more than the current aftermarket.

My only complaint is the Stupid Phuckers should have came out with these heads 6 months ago and they'd be on my car. Cause there's no way in heck I'm going to pull my engine apart again till I blow it back up or I can have some other monkey do the work.

That seems like quite a package. picking up nearly 50 hp on an already built car is something to be in awe of.

I get the feeling that these things are going to go amazing with some F/I!
