We have some creative thinking here, and i admire it. We also have a lot of machine work to get to 300.9 cid -- that is, if a 248 block will take a 3.905-inch bore, which some of us seriously doubt. If the 248 does take that overbore, it will -- like the 4.125 in my 302 -- be the last one.

A stock-displacement 302 could be built with far less machime work and a greater tolerance for rpm than a bored and stroked 248 that does not quite match the 302 in displacement or, i daresay, in power. In the long run the 302 will be far less expensive to build and maintain, and infinitely more durable.

God's Peace to you.
