ok i wanna change the eninge in my 305 5spd car into a 350 im hopping up the the 350 pretty wild but i know the knock senser and the fuel injectors i have to change but what about everything else like thye computer am i going to run into any trouble?

 

The ECU is the same. The chip will have to be programmed for the 350 however. Also you will have to be carefull with the T-5 on a heavily modded 350. If your not good at driving a stick you'll tear it up quickly.

I have read many times that the T-5's don't hold up to well. Especially not in a highly moddified car. However there are I think two users on here that have T-5's with LT1's and they are doing ok. That could be a result of good driving skill. Manuals are often less reliable only because the people that drive them are idiots. So if your not gentle with the T-5 you could be looking at problems.

A T-56 swap would be benifficial down the road. It can be made to handle ALOT of power.

 

um my car is atually a 350 tpi and i want to put the 5 spd tranny in it

 

You don't have to change the computer at all in order to put in the 5 speed.

However, from the tone of your typing, I'll predict that the T-5 will not last very long at all in your car.
