Help with cam specs

[sbh126]

I have a custom ground camshaft and I dont know alot about what all the numbers mean. Could someone break it down for me and tell me how it'll run with my combo? It's a 77 block with a 69 forged crank, stock rods, kb237 pistons .040 over, 440 source stealth heads, 10.7ish compression, edelbrock dual plane intake, 750 holley carb, schumaker headers 2" primary 3" collectors. 4 speed, 8 3/4 with 3.55 gears. 24" tall wheels.
What kind of power can I expect with this cam? How streetable will it be? Any other info you can tell me about it would be greatly appreciated.

Engine isn't in the car yet but will be shortly. What should the timing be set at with this combo?

It will run good.

That's a pretty mild cam for your build, shouldn't be a problem. With that comp ratio and those heads I'd take her up a notch or two, but that's just me.

I'd start the timing at 12deg initial, all in by 2400 RPM and total (initial+centifugal) at 36. Then build from there. Don't play with the vacuum, if you got it, till much later.
