how much power am i making

[josh110781]

i just rebuilt my engine. i have a 2000 trans am ws6. it was bored 25 over. i put in a cam with a 237,242 with a .603 and .609 lift. i have ls6 cnc ported heads. pacesetter long tube headers and offroad y-pipe with magnaflow catback. bolt ons are all slp. lid , smooth bellow, mass air flow. i have a 4:10 gear in the rear the only thing i have not yet done is throttlebody and intake. ran out of money. but that will be next with a 120 shot of nos. so how much power am i looking at. also what type of oil is best to break in an engine

Dude, the only way you are going to know is to put it on a dyno. Guesses will get you nowhere quickly, no one can guess how much power you will really have.

my guess would be around 445 and 570 when you spray it

is that at the rear wheels. i plan i getting it dyno in the spring but was just curious.
