That comp grind that is very close to the Old Faithful cam is almost always a great choice in these engines. It's hard to mess that up as a hot street engine with good manners.

I've run a 232/238 112 on as cast KRE heads in a +0.030 455 and that engine made great torque and power, but I always felt like I wanted a bit more cam. I currently run a 240/248 112 on a +0.040 455 with 310cfm KRE D-ports. This cam rocks. There's power everywhere and with the torque converter I run that stalls at about 3200 rpm behind the engine, traction is a real issue. With my setup, the driving manners are actually very good. There's enough stall to soak up any awkwardness below about 1400 rpm. If I was running a tight torque converter, or a manual transmission, it's possible there might be a slight amount of bucking around 1200 rpm in loaded high gear. Vacuum would be a concern if running power brakes.

The Butler custom grind will be somewhat similar, erring towards a little bit more manners and the 113 LSA is going to provide a bit more vacuum. That Comp grind though is likely a great compromise between street manners and performance. I think you're going to see between 500-530hp and around 550-570 torque out of that cam with your combination. It's will probably also be a bit easier to tune with your dual quad setup and will likely run power brakes.

Powell's cam in my eyes is too small for a stroker 400 and I don't believe your heads need that much exhaust duration split, especially if you're going to be running headers. I also think the 110LSA with 3 degrees of advance in it is going to plow a bunch of torque lower in the rev range and run out of steam early.
