ok so if i put a older 350 thats carbed and took off the car and intake and put a edelbrock performer intake with adapter and put on a holley throttle body would that work if i replaced the knock sensor and esc and a tune? where can i buy a esc besides a junk yard

 

you'll need a distributer from a tbi motor an i'd order the ebl flash to tune with from dynamic efi . but yes it will work . you'll also need a fuel pump that can deliver at least 30 psi if your gonna mod the 350 or at least 15 psi if not .

for your new ecu an tuning ability :
