Factory 318 EFI in a Dakota - mo power?

This is a small list of what is out there;

Super charger
Dual and single plane intakes
Hughes engines has a dual plane FI set up. Really nice.
Hughes engines also modifes the the throttle body.
1.7 roller rockers
Edelbrock heads
Headers
Cams from many sources

The supercharger will out strip the budget alone.
A cam, headers, exhaust and intake with throttle body mod from Hughes engines will be about 2K, slightly more if you try trick dual exhaust under that chassis. Twin pipes under that truck is very very tight. I own a '03. I don't see it happening and taking the same path as stock. This would drop the pipes down under the chassis and be viewable from the side.
