I also have run 2 4779 with no power valves sg jetted @ 78 with choke horns milled off. I also run them some sg jetted @ 80. Don't let anyone fool you they have unreal low-end throttle respond. And they don't look bad either.
I almost forgot the tunnel rams for some reason like a lot of CFM. I have been running tunnel-rams since the 80's. My new engine has a tunnel-ram with 2 Terminators(2950 cfm).
The mistake most people make on the Mopar wedge engine is they like a lot more CFM & fuel than the xxx brand engines.
