Yes, the Holley model 1920 used on early Mopar Slant 6's works fantastic on a smaller GM engine like a 235 or 230.
I have on on a 235 engine,the 1920 bolts on no problem,ya have to weld on a small tab on the throttle arm and figure out a choke situation,or in warmer areas,no choke is needed.The 1900 series Hollys use the same main jets as the very common Holley modular 4 bbls.
The engine runs much smoother,has sharper throttle response, more power and the same or better fuel mileage than any Rochester single barrel carb.
