So I just had a 350 droped into my 89 which was previously a 305. Everything is stock as far as fuel/air mixture and exhaust and comp= crappy running 350. So i bought a few, hopefully, upgrades and i want to see if you guys think I made the right move so here it goes:

I bought
1. A custom 350 chip moddied for some extra hp(right now I still got the 305 chip and comp.)
2. 50mm bore bottom half of a tbi unit(right now stock what 42/43mm bore)
3. 350 injectors 55#/hr with adjustable FPR(right now stock 40#/hr)
4. Pod spacer and im deciding if i should go ahead on the TB spacer.
5. 350 knock sensor

First is this going to work? Is there anything I should look out for? Is the fact that my intake has a stock bore going to complicate things with buying a larger tbi bore? Is the chip going to freak? Please let me know, thanks.

 

Try checking around in the "Engine Swap" and "TBI" sections. You can usually find a lot of information on swapping a 305 TBI for a 350 TBI.
