Answer 1

dont know the compression ratio-however if set up properly with curved distributor cam dialed in and in general proper assembly and set up / right around 375-400hp - and that is with every thing set up right on the edge" and dialed in correctly. im assuming youre running an aluminum aftermarket intake designed to run in the rpm range in accordance with your other equipment. make sure your running a rear end gear of at least 4.11:1 to take advantage of your setup . light camaro+ quick reving small block = really quick street machine. go kill those rice burners!.

Answer 3

my calculations reason I took long is your vehicle is producing around 240hp and 290ftlbs of torque give or take 25% accuracy I could be wrong just go to www.howstuff works.com and figure out the formulas by searching for what you are looking for. My calculations were based on my interpretation of the numbers you provided for the different components on some I converted from imperial to metric so I could be wrong.

Answer 4

You can take the vehicle to a garage that has a dyno to spec the hp. It might cost alot but they will give you the approximate rate.

Answer 5

the only true way is to put the car on a dynometer
