carburetor to tbi

[cwtint]

i am going to take out my stock 305 and th350 out of my 86 silverado and put in a tbi 350 and 700R4 from an 87 silverado. is there anything i need to look out for special part or customizing wise?

Fuel Injection Tank, Sender Unit and Pump...
ECM for Fuel injection engine...
Harness for Engine Compartment
Harness for Interior

The engine Must have a cam for a TBI or it will run like crap.

Ignition System for a TBI

i have all of the stock parts from the 87 like the computer and harness and all of that came with the motor i bought. The stock motor and transmission i am going to take out and probably sell. If i use the cam that was in this other motor i bought from the factory it should run fine right? i am going to have the engine overhauled and everything will be like new. is it better to go ahead and have the stock heads rebuilt or would the camel hump 202s be better to have rebuilt and put those on instead

TBI intake manifolds have a different bolt pattern than the 202's  And the TBI Intake won't bolt up without adapters.
The Carbed heads also have a different bolt pattern than the TBI heads and the TBI intake will not bolt up without adapters.


If you are dropping in a donor motor all setup for TBI you shouldn't have to much trouble.
