How can you tell if you have too much carb ?

[RacerX10]

I'm about to start running a 604 at some local races (in a late model)

I've got a 750 CFM demon race carb available that I'd like to use because it won't cost me anything to do it .. but I know that people generally seem to recommend 650 CFM carbs for these crate engines.

I suspect it will be just fine .. but how will I know if it isn't ? What should I be looking for ?

Thanks !

How you can tell, the engine won't have any torque coming off of the turn and it will just feel real lazy.
There are some thing's that can be done to help that though. It can be done by booster design and calibration.

If you ever need anything done to them let me know. I do a lot of demon's, there isn't to many carb builder's that will mess with them.
