I did utilize the search function and due to limited information why I posed the question.
Both these companies have some competitive pricing with dyno, break-in service and warranty. So they have sparked my interest.
Craft is on my radar as well.
@incoming- so you got your engine from one of them, which one? Carolina Machine Engines since they are in your neck of the woods?

I've built thousands of them (when I still owned CHP). Still do it, but that's not what I'm shooting for here.....I'd suggest aiming a bit higher since keeping the output down to that would probably dictate using a flat tappet cam.
I'd going to guess that you are going with a Dart block 4.125 x 4.000 stroker setup. So a smooth running engine would be about 10.25:1, AFR 185 heads (or equivalent...flow matters, brand does not) and a hydraulic roller of about .575 lift. That will net you high 500 H/P and low 500 torque. 91 octane friendly and very easy to drive. My own choice would be a Holley sniper injection system, and that's always a personal preference.
A good dual plane would give you better average horsepower number, and a single plane will give you higher peak numbers. We did a 408 for Engine Masters a few years back that would provide the data.
Anyone that suggest anything more complicated than that is just funning you.
I "know" both companies, in that I've sold a lot of parts to both of them. But that's the wrong side of the relationship to recommend from.
