carb choice and slick size

If you are serious about performance go with one of the holley double pumpers...even if it is a Proform or QFT...the parts are easier to find and get with a holley based carb.

Most A bodies with fit a 9 x 28 slick with minor problems...if you are using a 14 inch diameter wheel..there is a limited number of sizes available...there are some 8 x 26.5 slicks also..
