Autocross Motor Advise

Not an autocrosser (yet) but I used to be an engine builder....

You want SMOOTH power. Everyone here is correct, big power is not going to make the drivers job any easier especially on a tight course. I nice flat torque curve will make have a larger "sweet spot" so speak.

Not sure that actually helps with your question but an good engine builder (drag or otherwise) should be able to get you an engine that will work for your application. A road course builder might have to take less educated guesses than a drag race engine builder but they both should be able to build you a reliable piece for the autocross. It would be very helpful if you could give them a RPM range you would like the engine to make peal torque, they can work around that for head and cam sizing.
