I'm putting this engine in my 2000 s-10...

95 350 bored 30 over
speed pro flat tops 10.5:1
stock rods resized with arp bolts
stock crank turned
RHS 2.02 1.60 iron heads
professional products crosswind intake
224/224 @ 50 480/480 lift cam I think it's 108 degree lobe seperation
holly 750 cfm
accel hei distributor/coil/wires
hedman shorty headers
flowmaster 2 1/2" 40 series mufflers

How much hp should this setup make? Is this a good cam? The engine builder picked it out....I told him I wanted a rough idle but I'm not sure this is the right cam.
Thanks
