I need some advice on carb size.

I run a 455 Olds engine all standard apart from an Edelbrock performer inlet and headers.

My question is will a Holley 650 double pumper be too big to run the engine just for everyday use?

Double pumper is not so clever on a heavyweight automatic with low numerical axle ratio - unless you can exercise significant restraint on your right foot!!!!!!! - size otherwise is fine - as has been said - check out primary jetting.

Cheers for the replies will check the jets (sound like Dennis Wilson in Two Lane now lol)
