Default vortec headed 355

Okay so ive got a small block and ill tell yall everything i know and im hoping youll give me a close number on the horsepower/torque range. Its a 350 that was bored .030" and equipped with flat top pistons (6 cc valve reliefs) maybe a few thousand miles because you can see where it was honed by the shop. A small cam (rv/mild/3 quarter race/torque cam) not sure of specs but nothing serious. Forged 5.7 rods, and thats all for internals. Will have stock 350 vortec heads(64cc,1.94/1.5) port matched with a midrise dual plane aluminum intake. It will have hooker long tube competition headers(1-5/8,3" collectors) and topped off with an edelbrock 650 cfm performer series. Im hoping for close to 300 horsepower but ive been told 300 is easy with vortec heads. Its going in a 98 c1500 with a rebuilt 700r4. 3.42 posi. Itll have 2.25" dual exhaust with some strait through mufflers. Horsepower? About 10-10.5:1 compression on 93 octane.
