305 to 350tbi swap
Here is what i'm working with right now
Chev 350 late model block bored 20 over
993 heads worked w/ 2.02/1.60 valves
CR 9.32
induction (still in the works)
small tube headers w/ muffler dynomax headers, catback, and SS ultraflow muffler
Cam Lunait 50143 @.050 lift .471/.480
looking at 350 HP at the wheels
Desktop dyno says HP 388 torque 438 which is close enough for me.
I also have bought a 700R4 from Dana at Pro-built and also a converter. great guy very knowledgible in all areas engines and trans. sorry for my spelling.
Anything else anyone can think of i can use or need. thanks

Yeah , your gonna need a 670 cfm throttle body if your keeping the tbi and a custom tuned chip for your 350.Otherwise youll never get it to run right because of the damn computer.
Would it totally ruin the engine if you kept the same knock sensor and spark control module? The guy that's swapping my engine for me next week says he wants to try and use the 305 knock sensor and spark control module and work from there. I have the 350 chip from tbichips.com and kinda want to keep this swap as cheap as possible.

I still havent changed the knock sensor or esc module on mine and I have been running it like that for a year no problem. It runs perfect. I am told that swapping the knock sensor and esc module helps peformence a little and also ecomony but like you I am on a budget and it runs fine now so I dont want to mess with it.
