There's no such thing as a carb that's too big.....

Think about it. What happens when a bone stock 302 is wide open throttle, and running about 2500 RPM? It only needs just a little bit of airflow. So if the carb is 500 CFM, then it's too big

there's a hell of a lot more to a carb than it's CFM size. Just as I stated before...I ran 1050's on 302's for years with great success. They sure looked weird though. The carb was as wide as the rest of the motor. You CAN tune the carb FOR the motor, but generally they're pretty close right out of the box. notice I said GENERALLY. I've seen/had some Demons among others that were so far off of a tune that they would run like poo on anything but a lawn mower.

I say bolt that sucker on there & go drive it. I think you'll be surprised how well it will work.
