if the carb is adjusted correctly, it will run just fine. i run a quadrajunk on my 67 that was built by a local guy that really knows his stuff. i had a demon and he built this thing for my combo-they're about 750 cfm or so and it really woke up my car-smoother acceleration, great throttle response, etc. 670 cfm with your mods (=good volumetric efficiency) should be no problem :D
