Hi Guys, working on a 355 I want to build for the street to have fun but really stumped on cam technical stuff I don't understand. So I'm asking for your feedback please.

First, what I've got, 350 +0.30, 2 piece rear seal, 4-bolt, hyper dished pistons, moly rings, ARP rod and main bolts, 7 qt. oil pan, 10/10 crank, new balancer and sfi flexplate, (dished pistons so I can run 9.0:1 with a 64cc head),
air-gap intake, (Professional Products for use with or without vortec heads), 1-5/8" headers, 2-1/2" full exh w/Flowmasters, Holley 650 dbl. pump.

I need my topend, alum. heads, ('cuz I want alum. heads), Trick Flow, Edelbrock E-Tec 170, 200 or RPM, not AFR out of my price range and too overkill for what I'm using this engine for. Going in a 3500 lb. car with 3.89:1 gears, 200R4 trans with 2200 stall. Mainly street use, shows and cruising, want to do powertour next year so I want it to sound good! Have manual four wheel disc brakes, so no concern for vacuum, but do have Vintage Air.

Was looking at thumpr cams, love the sound but costing me power! U-Tube videos on them are quite convincing. Hyd or hyd. roller- much sound difference?

Sorry for the long description, just hope I didn't leave much out.

Thanks.
