hey all, well, the weather is getting good and I'm ready to swap the 396 out of my K20. I figure the mileage can't get ANY worse than it is, so I might as well have more torque. The local wrecker has a TBI 454, but no carbed versions. What advice can you give me? I know nothing abnout TBI, should I swap on a carb? How much extra wiring is needed, the truck already has HEI ignition. New fuel pump? When swapped in, the extent of motor mods will be headers and dual exhaust, or in the case of carbing it, a aluminum intake as well. Should I go for the TBI?
