Stroker recipe estimate

Hi everyone.
New here. First post. Total stroker noob.
Not sure if this the right spot or even if my question can be answered, but here goes.

Just bought a 4.7L stroker, engine was professionally built and blueprinted about 6 yrs ago...never installed and all the info I have on the engine is a photo of the list of parts used.

So my question is...

Based on this recipe
4.7L (283 ci)
High flow head
Federal Mogul coated skirt pistons
Clevite bearings
Moly Rings
Roller chain
Hardened pushrods
High volume oil pump
Roller Rockers
Header
F.I. Intake manifold
25lbs injectors

Is there any way of guesimating the HP/Torque and if any should be added? One thing that jumps out at me is, no mention of a cam.

This will be going in my race Jeep, so obviously want as big a numbers as possible. ;) and let me know if I should do any more to make it better but not into the realm of unreliable.

Any advice on my first stroker is freaky appreciated.

Thanks!

Without knowing the cam specs, compression ratio, and head flow numbers, it's difficult to make a reasonably accurate estimate of HP/TQ.
It does look like that engine was built with the shorter 4.2L connecting rods and Sealed Power pistons though, so it'll somewhat resemble a "poor man's" recipe.
