Put on a stock 283. The 450 CFM should be perfect for a 283. Once I got timing set correctly, it started right up! Idle adjustments were easy. Throttle response is way better than the 2bbl I had on it.

Fantastic carb-instant difference.

I put that carb on a 273 mopar LA small block. Matches perfect for such a small engine, but is slso very sensitive regarding the fuel pressure, had to install a regulator to keep it to the recommend 6.5 psi
