Not easily, and what gains are you expecting?

Wouldn't have thought it would be cost effective either, find a manifold, changing ECU, is there room, re designing the Air Feed, tbh think its a non starter, unless you're prepared to throw money at it.

Well you need to borrow gixers plasma cutter to cut a hole in the plenum,then bolt the holly to it.,then change the jets to some about 1.25, fit a adjustable fuel pressure regulator,set at 4.25bar,also might need an auxiliary fuel pump.

install a custom ecu, custom map, bigger injectors and make a richer air fuel ratio..   you wont need to cut anything..

Not forgetting that the four barrel Holley is a type of carburetor... and not compatible with the fuel injected electronics fitted...

Has anyone else noticed the full moon ::)

Doesn't mean it can't be done.  I can't think of a reason why anyone would bother, but maybe its a specific show car?

I can't think of a single reason for switching from injection to carbs these days. Even if completely replacing the whole induction setup, and radically tuning the engine, fuel injection is a no-brainer, IMHO. It's not significantly more expensive, it's much easier to tune and, if done well, can give you performance, economy and flexibility. Carbs can only give you two of those at any one time (and often don't manage that!).

holley is an ancient carb and I cant think of a pistonhead never hearing about it..


on a fuel injected car using a carburettor is unnecessary imo.. there are many types of performance injectors that can spray fuel many times than a big carb..  but problem will be pushing air in to the bores which will be a bit hard without induction
