318 build up

Swinger, for a comfortable, hassle free daily driver that will see no track time,....
if your going to rebuild the engine, I'd use stock replacement pistons and a mild cam with the stock heads. OR shoot for a 9.5-1 max ratio. The KB167 pistons and a thick head gasket will do this.

IMO, I would skip the Edebrock cam and use something a little larger. I'd look at a Comp Cams XE256H. It has a little more on the exhaust duration to help it breath.
With what you have, this engine will produce about 270 HP and a great torque curve with plenty from start to finish.

I would not use 340/360 heads.
