OK. This is probably a dumb question as I realize there are a lot of different variables here. I bought an '82 AMC 360 and rebuilt it. The only things I added were a new mellings mta-1 cam and lifters, edelbrock 2131 four barrel intake and an Edelbrock 600cfm carburetor. I did replace all bearings and such. I was wondering what type of numbers HP and Torque i can expect, (ROUGHLY). I know there are as many variables as responses, but just wondering if someone has a similar build and what kind of numbers they are getting.

Well, they weren't exactly power houses to start with in those years. In '82, the AMC 360 was rated at a whopping 129hp, 245ft/lb of torque with all that wonderful air injection equipment.
Older ones without so much emissions gear and motocraft 4bbls were rated as high as 195hp. Maybe you can get close to that.

IIRC, that Melling cam has the same specs as the Edelbrock Performer, and here is Edelbrock's dyno for a 304 with the Performer intake & cam, plus headers.

I put the Edelbrock in my 360, and even with the factory 2 bbl intake and MC2100, it was a noticeable difference over stock. My butt dyno says better torque just above idle, but runs out of breath around 4500. I'm sure an intake and 4 bbl would probably help out, but the little Motorcraft just runs too well offroad for me to toss it.

with out what is specked in the motor, the dyno means little to nothing. so much can be done that is not known to get numbers that its most sales pitch. set up is everything.
depending on years the CR will vary a lot, or what Cr did you install, pre 1970 tend to have more CR after the 70s stock CR is rather low. Running out of breath is one of two things. The ability to flow in and out and CR. The valves and head will limit flow no matter how big the carb or Cam. You can put a tunnel ram on it and that will not make the heads flow more.
Off road unless you are doing WOT mud bogs. Wot hill climbs. you want the engine to preform better in the low end any way. Now if you are the WOT wheeler. You need to build the engine to perform in 3-7k rpm range.
For a trail jeep its best to build for reliability more than power. So the OP best thing is to not worry about dyno bragging rights and just hope it runs well and last a long time.
