One of mine has the tbi on it. Btw dangerranger. Used the holley pro-jection tbi kit goes for around $300. I have bought 3 this way.
Jacob, you are being extremely vague. Are you asking about holley 2bbl tbi? 4bbl tbi? Both of which bolt to any carb manifold. Are you asking about the holley HP, dominator, terminator, avenger, or commander when used with a holley MPFI manifold?
Or holley HP, dominator, terminator, avenger, or commander when used with a ford MPFI stock manifold?
"holley efi" isn't just one thing. It spans from the simple/primitive 2bbl tbi systems with an analog ecu. All the way up to complex digital systems with obdii capability, the ability to self-tune, the ability
To run 32 injectors sequentially, the ability to control boost, nitrous, propane, or methanol injection. The ability to control fuel/timing curves for each cylinder independently.
You see, its a broad variety. Not just one, or two
