Q: Looking at this product (as well at the thermostat housing) for a street car application. Supercharged LS3 in a 63 Nova. Not sure if I should use the -16 or -20 adapters. Will the -16 flow enough coolant for my application?

Hi,you can technically use either -16an or -20an. -16an will work fine if you are keeping the radiator up front. If you were to relocate the radiator to the back of the vehicle, we would highly recommend a -20an. Most people run the -20an just to be safe since it is closer to the factory size hose. Also make sure your water pump flows enough gallons per hour for your application. Thanks.

Q: For CBM-10622 the description states that Genuine OEM water pumps will fit. I have an ACDELCO water pump but I didn't purchase it from Chevy. Is CBM-10622 the correct adapter for me?

Hello,

As long as you know the brand is truly AC Delco, it doesnt matter where it was purchased. The CBM-10622 would be the correct part for your application.

Thanks
