"Then add in the fact that he is probably still using the 305 ECM, Injectors, Knock sensor, etc, it is likely that the 350 runs WORSE than the 305 did. For $200.00 I would invest in a 350 ECM, 61 lb/hr 350 injectors, AFPR, and 350 knock sensor." - Fast355

I was reading through another thread and saw that quote. My car had a 305 to 350 swap, I have no clue if the previous owner upgraded up to the 350 ECM and all that. If he didn't, how much better will it run with the 350 ecm? Also, where would I go abouts getting this ECM. I contacted the ownder with the question and once he replies back i will know what to do. Thanks guys.

 

Other then the unique KS and module for each displacement engine, theres not much you can do other then to tune the car. There really isnt a '350' ECM, or chip, unless your using a stock L05.

 

So, what are them two things called specifically, should I get them? Also, my oil needs changed in about 2k miles, I am going to do a full tuneup as well then.
