With a decent aftermarket intake + carb, you might gain a little. Being in the heavy truck, you probably won't notice any increase. And...



I'd love to build an old F100 pro street truck.

You will need to replace the distributor since the EFI distributor has no spark advance mechanism. One from an 85 5.0 Mustang with a duraspark box would be the best choice.

Cruse the classic forum for more help or see http://www.jason.fletcher.net/default.htm for more on carb conversions.
