Only difference would be the fact that it was a 2 barrell engine... Some of the 4V's had the GT heads and cam, made for a 390 horse torque monster....

There's a bunch of different stroker kits available for the FE's, makes a high torque engine have even more torque..... Also a couple companies making Aluminum heads for the FE's, along with roller cams and anything else you could want. Big question is, how much do you want to spend???? Best to have a budget in mind, then carefully select the best components for the money you want to spend. Also select components that will work together towards achieving what the engine is best at doing, making big torque at low to moderate RPM levels.....

or, as with any aspect of Hot Rodding, plan your work, work your plan........
