I have a nice-to-have problem.

My engine builder called yesterday. The 427 Windsor (Dart) they have built for me is making significantly more power than expected in early testing: 550hp @5800 RPM.

I don't have the specifics, nor am I an engine expert. I know we purposely picked a milder cam to calm the motor down and make it more drivable. Even with a 750 carb, it seems to be pulling well north of 500hp, past 6100 RPM.

I love the idea of a 427 monster under the hood of my new build, but I'd like to reduce the power a bit more.

Is there a smart way to reduce the (carb) throttle? Can I adjust the cable so the pedal hits the floor shy of wide open throttle? Other suggestions?
