This, and a 450 /500 Carter AFB/Eddy... I actually .like these carbs here.. If you are not proficient at carbs, send RustyRatRod ,a holler... Honest as hell, he actually knows enough seat time wrenching to set you up,once...and right...
Yes, or if he likes Holley, I would recommend the 80457.
It's a 600 vac secondary with electric choke. I've used them for decades on daily drivers and once the choke is set up properly to a 12v source, you just start it up and go with no stalling, even below 20° F, I would pump the gas pedal twice, crank it over, watch the oil pressure come up, then put it in gear and drive off in midwest winters that can get below 0° F sometimes...
With vacuum secondary, you can't over carb, as it will only feed what the engine needs....
But as far as out of the box, the Carter/Edelbrock is an easy bolt on and go with minimal tuning required. Holleys take a little bit of tuning knowledge to get them dialed in properly, but run great when you do...
