97 vs 94

[jack backer]

Sourcing the correct power valve for the 94 is nearly impossible new. However, harvesting the power valves from junk 94’s works..7.5 inches vacuum is the correct setting for an A, the valves are stamped with the crack pressure.

94 is a ‘smart’ carb, it listens to engine vacuum to enrich the fuel air mixture during acceleration.

Couple it with a mechanical advance distributor, high compression head and a more aggressive cam than stock and the engine really wakes up.. Ford detuned hell out of them.. the best part is the torque rises as well , that's what makes the A fun to drive stock.. it funner with the engine efficiency is raised and potential is realized.Some believe you are abusing the engine ‘hopping’ it up.. it’s the contrary, it actually runs efficiently and cooler, with no risk to properly maintained rod and main bearings
