dyno program on computer

if anyone here has a dyno program, could they help me out? i want to see what this certain combo is supposed to make, at least roughly anyways...

350 smallblock bottom end

L31 vortec heads in stock setup except modified for higher lift camshaft (9.5:1 compression with typical cast pistons and whatever head gasket needed for 9.5:1 or a little bit higher as long as it can run on 91 octane)

edelbrock vortec-style intake rpm air gap

comp cams 274 Xtreme Energy camshaft hydraulic flat tappet going thru 1.6 ratio rockers instead of stock 1.5 ones.

Holley vaccuum secondary 750cfm carburetor

1 5/8 inch long tube headers with turbo mufflers

p.s. if possible, could you switch out the vortec heads for the newer bow-tie small intake port vortec heads that are supposed to be better? they have 180 cc intake instead of the older vortec's 175 i think and 2inch intake valve, 1.55 inch exhaust valve, and can support up to .530 inch lift, so i might get them instead...

if anyone can try this out i would greatly appreciate it... thanks for your time...
