Factory Holley carb?

yes you can for a stock 12a its a 465 cfm you put a threaded hose nipple in the primary float bowl side where the sight hole is for setting the float bowl level ,you will also need to make a bracket for the throttle cable and then make an arm and rod for the oil metering block .I have owned quite a few holleys and the only thing you need to find out is the jet sizes. Usually the RB holleys are set up a little lean on the secondary side(at sea level) and if its a vac secondary then the spring can be changed to open with less vac signal. RB can tell you what carb to use for motor size and port .If it was my car then a weber would be my pic. Better fuel delivery and no hesitation around sharp corners ,even with center hung bowels there is still a hesitation with the holley . Good luck.
