What kind of fuel pump does a TBI 454 have?
Stock TBI 454 makes 230hp and 380tq so stock fuel pump is maxed out right off and a typical 454 will run better with a fuel pump upgrade even with stock chip. GAS MILEAGE. Always a big complaint with 454 TBI trucks. 90 and older is particularly bad and that is largely due to NO OVERDRIVE.
Can you change the intake manifold on a TBI?
Intake manifold. On the 87-90 Mark IV blocks that have the crappy iron carb intake. yes change that to the Edelbrock 3764 especially if your upgrading that cam. On the Mark V 91-95 engines. With stock cam, nothing to be gained from that change.
Do you need an adjustable fuel pressure regulator for a TBI system?
