Q: Carb to suit a mild 318 stroker

dfoyl

Welcome aboard!

At 383 cubes...or so... the carb size should be part of the package. You wrote street duty. From this, I'll assume your not exactly building a high HP engine, just something with muscle.
Can you provide cam specs and tire size?

625 cfm is not to small in one area, but small in another. Stock B block 383's came with small Carters of that rating years back. The early big blocks were not very high in HP. So the smaller carb works great. Once you cam the engine with headers and etc.. stuff, the 383 B engines really woke up well with the larger Carters @ 750 cfm.

You'd be the first to build a stroker without the idea of mashing the pedal, so I'm sure, the engine/car will be put through a few paces and you'll hit the gas hard. Just to get on the Hwy or pass someone on it.


The previously mentioned carb will work well for a mild manored stroker small block. A larger 750 would be preety good for mild racing.
