360 Rebuild for 1974 Swinger

Those pistons and a .028 head gasket will get you 8.7 to 1. The cam will be ok for what you want. Bowl port the heads and call it good. If the intake is a performer, it will have the 318 ports, so match them to the heads. Get a 8.25 or 8.75 as soon as you can afford it. Hopefully 318 will run will chime in. He has a combo similar that runs excellent. Most of all, have fun.
