Maybe, depends on the Ford and the heads. FE Fords don't make a lot power, but the 385 series can make big power. I have a 521 Ford with Kaase heads that is ready to go on the dyno. I think it will make around 850 hp. The heads can make a lot more power but there aren't really good intakes available for that engine. Kaase has built some bigger SR-71 engines that make a ton of power so it can be done.

The Mopar BB is basically a truck engine. That is why it has the tall deck, tall pistons, heavy skirt, tiny ports, etc. The Mopar engineers could've built a low deck 451 or 470 with MW heads back in the early 70's and kicked Chevy to the curb but they didn't do it. A low deck 470 with MW heads and a big 4bbl would've been surprised a lot of street guys back in 1972!
