But I'd try complete engine w/its own carb first. If it won't operate good, I'd try swapping carbs next. If it still operates bad, I'd swap carbs back AND swap computers as a last try, attempting by the earlier tries to keep the 4x4 computer with the 4x4 truck if at all possible. Luck to you and your new power and possibly better fuel mileage at the same time--best of both worlds! (A close friend put a Camaro 305 with tbi in his '86 S10 Blazer. At the same time, I put a Z28 350 with TPI [LT1] in my '86 Blazer. The 305 gets 13-16 mpg; 350 gets 18-23 mpg!!! Plus, the 305 has nowhere near the power of the 350.) s |
