What kind of power?

Somewhat similar to my build. Bigger cam though. I'm around the 400 mark.

Hard to guess power. Especially without more info on heads. If you're in the 10-11 area, you should be in the 400hp area. But yours will come in at higher rpm. Carb sounds a little small for the cam, might choke you at higher RPM. But that's just my opinion.

The biggest thing is the total package. Obviously yours was built and setup with some foresight. There's a lot more to a car than a (insert whatever hp) engine. A 400 horse engine that makes its power at 3500+ is useless without the proper drive train behind it. It's all pieces to a larger puzzle.

Sounds like you'll have fun with the new toy though! Get out and enjoy it!
