im trying to achieve my goal of 300 rwhp. would afr's 180 and comp cam extreme energy 268 along with holley 670 cfm tbi (502-9)and holley prjection intake get me to my goal?

 

You should be making over 300hp at the crank with that setup when properly tuned, But 300Hp at the wheels I think would take a little more than that. Just my 2c's.

 

what would i need to change to make my goal?

To get to 300 RWHP you'll have to assume 15 to 18% driveline losses. Given this you'll have to assume about 355 HP at the crank. To get there you'll need to do a bit of work which will involve the following:
1) Heads
2) Cam
3) Exhaust
4) Fuel delivery
5) ECM programing

i know about what to change. what i dont know is what to buy. does anybody know a good engine combination that can achive the 300rwhp goal?

 

A 383 would go a long way to achieving your goals.
