L 98 350 engine horsepower.

Putting together a mild street small block Chevy. I started with a 1991 L98 350. I overbored the block .030. had the block professionally baked and shotpeened, new cam bearings and brass soft plugs installed. I bought new weight matched hypereutectic speed pro flat top pistons/rings, had the connecting rods reconditioned, and the crankshaft polished (std/std). I'm using a ZZ4 camshaft-Hydraulic roller, and had the heads upgraded with all Lt4 springs,retainers,locks, and shims, and installed new swirl polished stainless valves with positive seals. The heads were resurfaced and treated to a 3 angle valve job. I'm running a Weiand dual plane intake with an Edelbrock performer carb. I'm thinking it will be @ 365-375 Hp. what do you think??
