The TBI ran great on the original 318 but would not run right on the magnum, Idle was about the only good thing it did. This was with the eddy intake and adapter on and big single exhaust and the 92 93 ex manifolds. I think the 318 TBI engine had 180 HP and the magnum was 235 so it just is not right. We eventually swapped in a 93 intake/harness/computer/fuel pimp and it ran awesome and yes there were a few wires to swap but no biggie.
Interesting, I would have thought it would have been close enough to run and drive ok, even if it wouldn't have made best power. I wonder if it would have done any better with a more restrictive stock TBI intake manifold?
