I have an 89 5.0 TBi and I will be swapping in a third gen 350 out of an iroc along with the 700r4 tranny any probs in doing the swap?

 

Are you going to use the throttle body injection still, or are you going to switch to tuned port?

Answering that question will help answer yours.

 

There could be lots of problems if you have missing parts or don't have any tools. I geuss we need more info.

 

well im not doing it but a friend is i guess the questin is am i going to need to chznge alot of stuff around the engine or do i need to buy new compatible 350 parts? Do i need a new computer because i heard the one from the 305 wont work with the 350. If i keep the tbi is it better than having the tpi ?

 

Both are junk when it boils down to it. Howeverm to go to TPI you are going to need a high flow fuel pump along with all th wirings and sensors that come off of the other motor. If you have all of the stuff out of the donor car the swap is straight forward.

 

ok thnx for the help

 

whats better than tpi?? mpfi?

 

Well TPI is mpfi but it is not a very good one. I would look into the LT1 intake swap or the stealth ram option. Another alternative is the miniram but it is quite expensive.

 

Of the two FI setups, I would go with TPI myself. The TBI is basically a CC 2bbl carb, but TPI is a real fuel injection system.

 

What you are trying to do is a waste of time for the gains to be made. A couple of reasons to many imcompatible parts, TBI 305 to TPI system. And if you don't have everthing for the TPI its going to be hard locating & the money factor. Think this project thru or you will have a undriveable car.

 

well im not sure but he has the whole engine with the tranny from the iroc and he said everything should just fit in so i dont know... il ask him maybe today or tomorrow...

 

No one questioned will the Engine & trannyl fit, Its the other important parts that will make it driveable that are important. One example: The wiring harness for the TPI and this is only one.

Everyione thinks a backyard engine swap is cheap because you have a motor. Big deal.

Let the screaming begin how cheap it can be done for. lala: :lala: :lala:
