Not sure why he'd need another carb?? Check Holley's website and make sure it's in original configuration. It's always best to start from there if it's been on another motor since calibrations can be substantially different from one engine to the next. If it's new, run it and see what happens. Learn to read your plugs if you don't know how and a wideband O2 kit for methanol is always a good purchase...

cause this carb has been on a few motors over the years. we were looking at other peoples similar setups and this carb is way different between jetting and air bleeds.
