Not even close to Chevy carbs. These are holley 4782 and 4783 carbs sold by holley, direct connection and hustle stuff specifically for use on 440 mopar.

Cheby carbs were vacuum, these were mechanical. These were sort of based on 390 or 406 Ferd carbs that were available in the early 60's but were different than those too.

They run awesome on my SB . Here's an old write up I did on the rebuild with some part numbers.

I bought this set up a few years back with air cleaner for under 2k. I think my set up is the same, can you guys confirm? I'm about to finish the build on my 71 Challenger and this is going on top of the 440 going in it.

Looks like them, to be sure, check the list numbers on the carbs, should be 4782 center and 4783 outboards

Btw keep the jetting close to stock, even my lowly 400hp SB likes 66 center and 80 outboards and that may be to lean!
