ok got an 5.7 tpi with mass air flow sensor, will the ecm from a 305 tpi work, i have changed cam and injectors,now have 32 psi injectors,can i just put a chip inmy 305 computer? thanks

 

Yes, you can use the ECM from a 305 TPI. Now your second question, NO. For starters the 350 will run with a 305 chip, but not very well. You will need a custom chip with your 350 specs. Fastchip.com is a good source.
