Kkosche,
Congratulations on a great purchase! That engine package will lay down some serious numbers when it’s tuned. Put a set of Drag radials on it quick!! It will be a scary bastard on those tires ( Goodyear Eagle GTII’s? yikes!!) Yea that cam with a big single plane and a Dominator = less than perfect drivability! Lol
But EFI is a great tamer of big cammed street cars, making it is easy to compensate for the weak vacuum signal . $10k should get it done, so long as you don’t get retail gouged.
I like the Kinsler SCJ manifold but they are pricey at around $6500(last I checked)

and the TWM set up. I just picked up this complete TWM set up with an older Electro-Motive computer for $2K!

I’m fairly sure I’m going to use the new Holley Dominator EFI controller.

I have a friend that does it for a living and he has nothing but good things to say about it. Very easy user interface, self tuning options, even a hand held tuner if you don’t want to use a laptop
