what kind of #'s am i looking at?

[m0rpheuslaugh1ng]

ive got an 87 silverado lwb with a 350 (.30) over
lunati cam .308 dur .540 lift
bowtie heads iron (not sure of specs)
forged crank/pistons 10:1 comp
headers/ dual 3 1/2 pipes (no cats) to flowmaster mufflers

i didnt build the motor so this is basically the only specs i know

its gotta a turbo 350 tranny with shift kit
and stock rear.

now the truck will haul ass, i havent raced to many people, but i did race an lt1 trans am and the truck absolutly raped his ass.  

anybody got any ideas?
