Im sure i can deal with that. So any help and suggestions would be highly appriciated. I dont have the magnum engine yet but theres a complete engine, trans, wiring setup for sale out of a -97 Dakota here for decent money.

If it's a small block, I would be tempted to swap just the engine & use my '89 parts as needed to make the '97 engine run. I did this with my '96 Mustang with a '04 engine. I re-used my ignition, timing cover and throttle body from the '96 and the '04 bolted right in. 70 Roadrunner convt. street car 440+6, NOS, 4-spd, SS springs '96 Mustang GT convt. street car '04 4.6 SOHC, NOS, auto, lowered "Officer, that button is for short on-ramps"

Yes, it will with a bit of work. But trying to keep the 89 TBI system is not worth that bit of work. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

My guess it that the TBI would work, but a GM TBI system conversion is more adjustable and hackable and therefore preferable.
