Wake up a 400?
I have a 78 4x4 150 supercab with a 400 and its just a dog. Its geared pretty high and this thing has trouble pulling itself out of a wet paperbag. Not interested in any gearing changes. Cruises nicely once you're up to speed! I had one guy say that a new timing chain set with a 4 degree offset does wonders for the 400. Just wondering if anyone else has had any experience with that or have any suggestions. Not an everyday driver.

Headers will help to with cam, intake manifold, 4 barl carb and timing set straight-up, but you haven't done anything yet to boost the compression like 79FordBlake said. With all this change will make a HUGE difference, you will probably think your in the wrong truck.

The February issue of Classic Trucks has an article about just this. They took a '76 400, cleaned it up, bored it over .030, installed Cleveland pistons, stock cam, and compared a 2v intake and carb to a 4v intake and Holley 750 4 barrel. They got some pretty decent numbers on the 4v setup, 301hp @ 4100 with 429 lb-ft of torque.
