Here is what I have.

78 Warlock, 727, 8 3/4 3.55, mini tubbed, running 295/40/18 on the street.

1972 400 block (short block assembled and zero decked)
3.90 stroke crank
H beam rods
CP flat tops

Stealth heads (bowl blended and cleaned up)
Comp 26120 beehive springs with retainers and 10 deg locks
Crane gold 1.6 rockers

Cam? Thinking MP .557 (not looking for aggressive ramp cam, This will be mostly street driven with occasional track days)
Intake? RPM or Victor/M1
Carb? I will start with an 850DP I have hanging on the wall.

I will have a converter built after I see what it will do on a dyno.

So let's hear some comments cam, intake and carb.

Comp should be just about 11-1. Exhaust currently is block hugger shorties with 2.5 all the way out, running Thrush muffs. Exhaust subject to change down the road, but it is what I will start with.

MP 528 solid and the Eddy performer rpm.Will make a solid combo especially with the 1.6 rockers.The 850 will be fine.

Those 1.6 rockers are going to speed up whatever cam you choose.Is a hyd cam an option? Hyd roller would be a nice choice.I might check the Lunati catalog.Everything else is fine.IMO 470 is probably the most efficient of the strokers.

I used the 296*/.557 Mopar solid cam with 1.5 Sig Erson rockers in a bracket 440 I built 30 years ago. It was mostly stock, "906" heads, 2.08 x 1.74 valves, no porting or blueprinting, heavy TRW 10.5 pistons, 6-pack rods, stock balance, single plane intake and a borrowed 850 DP. That cam was very civilized in that combo. You could go a lot bigger in a bigger motor and be just as civilized.

My new blueprinted 440 has a Comp hydraulic cam with more lift and duration with 1.6 adjustable
rockers. Not that I am lazy, but I don't want to be adjusting a solid cam anymore. This is my hobby, not my obsession

Mike, I have considered hyd roller, that was my initial plan, but for everyone that thought is was a good idea, I would have 5 that would tell me to stay away (cost, reliability, RPM). I'm still not opposed to the idea, for my initial reason, wiping a lobe. Wipe a lobe and you end up spending what a hyd roller would have cost, if not more.

The Lunati 294/302 looks to be the closest to the numbers I have been considering, but would likely be pushing the limits of the springs I have with the 1.6 rockers. Crane has some good looking numbers, but they are proud of them.

I think the RPM intake would provide more mid-range and fit your application best. Either the 528 or 557 MP cam should do fine... its a matter of "personality". Both have pretty long duration but the 528 should have better manners than the 557 and maybe a bit better fuel consumption if that matters.

It sounds like you will have perfect "quench" with zero deck... even so 11:1 may be pushing it on pump premium. The bigger cam may resist detonation better.

I personally like solid flat tappet's... make sure lifters are free to spin, assembly lube well, start up fast and run high zinc oil and there should be no problems.

Got me considering following close to this build.

I will be down 35 ci and around 11-1, but most of the rest would be very similar.

With 3.55 gears I would call comp cams. You want torque to move that truck. And also build enough vacuum to be happy driving it.

I have had a couple of things come up that have kept me from working on this project, but it looks like it's time to get back on it. I am however, still stuck on cam selection. I am currently considering the MP .557 or going hyd roller with something like Comp XR292HR. Just having a hard time pulling the trigger either way.
