Re: 78 K30 Carburetor Issue

A Qjet would be best , and get better mileage too.

The dbl pumper in question is so small for your 454 - the normal characteristics
don't quite apply. I'm sure it drives fine and has excellent throttle response , but if it were an 850 on a stock 454 - it would be a mismatch.

Do you have an aftermarket manifold, or is there an adapter under the carb ?
