What kind of horsepower to expect 383 build

I am almost done with a motor I built that for various reasons took way too long. Been about 8 years since started this project. I am close to installing it so I just figured I would do a little bench racing and see what I can expect. The motor In question is .060 over 383 built on a budget. It NOS Direct Connection forged pistons 11.5 to 1 compression ratio. The block has been decked and the flats of the pistons are at 0 deck height. Rods have been resized and crank turned .020 under. I installed a mopar purple cam I had in the garage. It is the .509 lift 292 on 112 centerline. Cam installed straight up. Heads are stock 906 heads with mopar valve springs. Stock rockers and pushrods. Rotating assembly is balanced. Running standard size headers. Still looking for an affordable carb but would like an 850 dp. I have a 750dp I can use off another car. Also running a Holley street dominator manifold. Anyway. What do you think?
