The early 90s 350 serpentine belt bracket and early 90s 454 serpentine brackets are the same size?
I'm keeping the 1990 454 motor throttle bottle
I know the years different with TPS sensors are different connectors
Motors staying factory specs. Also
Yes radiator is good to go also.
The truck is originally equipped with TBI 350.
The 454 has the carb intake with the TBI adapter plate that allows coolant flow
Questions on 454 ecm would inI the 454 ecm or could have a chip made for the 350 to 454 conversion?
