i was wondering how much a 347 would in mess with the factory computer? i understand that the a9 series ecu's can handle a certain percentage of change before it starts acting up. i was just wondering if anyone has this setup, and what they have done.

you mean you can run a stroker motor with a factor ecu? i thought the ecu knew the engine displacement for calculating load stuff.

Yes, you can run a stroker motor on a factory computer. I ran a stroker motor with a Novi 2000 and 60lb injectors on a stock A9P untuned.
