318 carb to replace or upgrade

[o1gnah]

Good day. I will be in need of a new carburetor for my 73’ 318 soonish as I attempt to rebuild and realized it’s done for. So the question I have is should I keep the original(In photo) or ask what you guys suggest as an upgrade. I’d prefer a direct bolt on without changing linkage and keep it simple. I am running the stock manifold, stock head, and short block w/ upgraded cam and high compression pistons.

If you buy it, keep your fingers crossed. With a upgraded cam and compression I would go 4 barrel intake and carb.

Ok, im coming across the Edelbrock 1400 and 1405 600 cfm. Now what is the manual vs. electric choke?

I like the electric choke myself. One wire hook up to a switched power source.manual choke you will have to operate from the driver's seat via a cable.

Ok, if you're considering a switch to 4-bbl, you're opening up a whole 'nother discussion.

Just be aware that the 318 cubic inch engines used a 1-1/4" Carter BBD Carb. And the 361 & 383 inch engines used a 1-1/2" Carter BBD Carb. The difference is the mounting flange bolt spacing and the throttle plate size. The 1-1/4" BBD carb has 1-7/16" throttle bores and the 1-1/2" BBD carb has 1-9/16" throttle bores.......the two sizes DO NOT INTERCHANGE......be sure what you are buying....

If you use the Edel carb [ excellent choice if you want to use a 4 bbl ], be aware that the manual choke versions are calibrated richer than the elec choke models.
