The headers aren't too bad but the GTS mufflers will cost you 50 HP
on a 400 HP to 500 HP engine.

By itself, with no other changes, a stroker kit does not have much of
an effect on peak power. It does allow you to make more power while
retaining your low end torque (with a cam change) or it allows you to
move the power curve down (make th same power at a lower RPM). It
sounds to me that either a 393C or 408C kit would do what you want.
Here's an update from Mike Drew who got the 408C we did for him
installed yesterday:

"I took the car for a quick drive around the block. WOW! It is
completely and utterly transformed. Cruising at low rpm in 2nd gear,
I punched it, and after bucking once (due to the aforementioned carb
issues), it just lit up the tires, no clutch required. Just ZING!
Even when the tires hooked up, the aluminum flywheel let it rev like
crazy right up to redline. This thing is crazy, crazy fast compared
to how it ran before. After owning this car for 21 years, I finally
have the car I was supposed to have all along!"

As far as reasonable cost, off-the-shelf, kits go SCAT is my choice.
I prefer the forged steel crank versions though we've also done the
cast crank versions. If the budget is a little larger, there are
other options when you piece it together yourself.

You can retain your iron 4V heads, RPM Air Gap intake and even the
Comp HR290 cam though I can work something up that works better
across the rev range and makes 500+ HP.
