1974 Thermoquad, 360 HD Truck , Rebuild adding performance modifications

Interesting thread. Two things have always been kind of intimidating to me with our old Mopars, and that is tuning Thermoquads and rebuilding Torqueflites! I plan to learn how to do both, so this thread should help with the one fear....lol. Somebody told me, or I read it somewhere, that you can use jets from a GM Quadrajet carb in Carter Thermoquads. Is that true or just some BS?
