I have an 86 iroc with a 305 thats seen its better days.... I plan on using a vortec 350 out of a 1997 chevy 1500,rebuilding it and running the tpi injection on it with the SDPC lower intake...

What I was woundering because from what i've read the newer style ecm's work a bit better, could I use the harness and ecm and everything from the vortec? rather than repin the harness...and what all it would take to do it?


I looked at the plugs on the throttle body for the TPS and IAC from my lt1 and i think it has the same plugs as the vortec? If so I could just use the tb from my lt1 along with the MAF from the vortec?

Will it even work? and any problems i'de run into doing this?

 

that manifold wont bolt onto that engine. you will need an 87 up intake, harness, ecm and a chip to match the change for injectors and engine

 

Yea it will....like i said before I'm using a SDPC lower intake that is specifically for the vortec heads using the tpi...

I was just woundering about using the harness and ecm from the vortec using an lt1 throttlebody if there was any problems i'de run into
