Ok My brother has a 1984 Trans am with a carb. We baught a TBI motor Complete with all accessories including Smog, power steering, Water Pump,Alt, All sensors, distributor.

It also Included the wiring harness and a 1227747 ECM. The engine cam out a a 1988 Full Size Blazer.

Now The First question is can We buy a External Electric Fuel Pump so We don't have to drop the tank. If so Where and What brands. Also What is it going to take to plum the fuel lines to the TBI Engine.

Besides a Electric fan What else Are we going to need or do before swapping.

(If this was a TPI swap I would know because I have Already done 3 of those.)

 

You can get away with an inline pump. Which one you choose is uo to you but you will want to pick one that can support more than 15 PSI. As for fueling you need a feed line and a return line. You can use rubber hoses with the correct fitting on the end to attach to the TBI unit. You are going to need the ECM and RPOM from any TBI car but you cannot mix and match computer stuff between the car version and truck version. Go with one or the other. If you do not have every sensor make sure you get ones for that new motor. Does this motor come with the distributor and everything?

 

The engine is complete with all sensors, wiring harness in good condition, distributor. Why would we need a ECM form a car I have the 747' Ecm from the vechicle. With a prom and Calpak.

Thanks for reminding me about a return line.

 

You are set to go. I thought you didn't have an ecm. If the car previously had a carbed 305 you will need to change the ECS module to a 350 one.

 

The '747 stuff should adapt just fine.

 

The wiring harness for the engine he baught was intertwinded with all th wiring in the vehicle. So I have to go through all the 747' diagrams I downloaded and cut out the stuff that isn't needed. Well One advantage is that the TBI engine even comes with the ESC module. :hail:

This was just to good of a buy Being that it is Complete in the Best Sense.for him to pass up so I Told him to BUY The Complete engine just not the Fuel Injection stuff.
