Hello List!
I have a real problem. I had an engine built. Then had a falling out with the builder. I'm sure the engine's fine, but I don't know the exact (or estimate) HP the engine produces. I'd like to have an Idea so I can decide on intake options. Here's the parts list.

4 bolt, bored .30 over, Comp cam. (Adv. Dur. 260/ 260, Lift .500/ .500),
Melling 'vette oil pickup screen, Hv oil pump and drive.
Comp pro roller rockers, Hyd roller lifters and springs. Cloyes true roller timing chain set.
GM Perf. 64cc iron vortec heads and Gm perf. TBI intake.
Headmann headers.
Stewart stage 2 waterpump, thermo, and bolt kit
3 row Proliance rad.
March crank and waterpump pulleys.

Can anyone help with this?

Thanks
