I would like to put my 305 Fuel Injection onto the 355 or will I have to get new stuff with better fuel injectors. I need some feed back please.
What do you recomend

 

If your new motor comes with a Stealth Ram already on it, then you won't need your TPI. You'll need a handful of parts off of it, like maybe the TB; that's about it.

You'll need new injectors. The stock 305 injectors will barely feed a 205 HP 305. A 420 HP motor will need about twice as much fuel (since as we all know, power does come from fuel...)

Your stock ECM will work, but will CERTAINLY need some programming. Expect it to run like hammered dog plop with the stock 305 programming.... if it even "runs" at all.

You'll need a 350 knock sensor and maybe ESC module.

 

Save your TPI or sell it believe it or not its worth alot of money. You need new injectors since your engine was a 305, new fuel rails, and you may want to get a reprogrammed prom. You can use your stock throttlebody and wiring harness/ecm, as stated you need a 350 knock sensor.

 

Mcdamit,
What do new fuel rails do for you?

 

They carry the fuel from the lines to the injectors; while attaching to this other completely different casting. Stock TPI lines won't work on a Stealth Ram.

 

Thank you. I didn't pay attention to the stealth ram part of the build up or I might have figured it out.
