383 stroker is in need #'s

[hurricane]

hello everyone, hoping someone can help me out, I bought this crate 383 stroker from a private seller and I am wondering what kind of horse power this might have here is what is in this motor, it has a crane cam with 520 lift, a rpm air gap intake, a set of E-Street edelbrock aluminum heads, probe flat top pistons, PRW rockers, HEI MSD distributor and a 6al MSD box and to finish off a set of Headman headers, with all this said is it possible for someone to tell me how much horse power this motor should put out.
Thank you all.

I would guess maybe 460-490? I'm not exactly sure, if you give me more detailed specs I can calculate it on Desktop Dyno tomorrow.

There's no way to make an educated guess here. We need alot more info like ALL of the cam specs, compression ratio, rocker ratio, head specs....

It sounds like it is close to the Edelbrock 383ci crate engine, which I believe puts out 425hp at the crank
