[442 chevy power]

hey guys, need some help. i bought a 70 455 olds
f block motor complete with c cast heads. all for 325.00. im wanting to make some serious horse power, so iwas talking to one of my olds buddies.
he said i could have my crank reground, and balanced, use big block chevy rods. to get a 493 stroker motor. is this true if it is what all do i need to do to do this any special pistons block work etc.

You would have to stroke the Olds motor about .250" and bore it .060 to achieve this, the stock olds engine is undersquare with a 4.125 bore size and a 4.25 inch stroke. You can achieve 468 cubes by simply boring it .060. I'm not sure if the cost of a stroker crank would be worth the 25 cubic inches you would end up with. More cubes would be nice, but this engine has a really long stroke as it is, and you could probably spend your dollars more effectively in other areas {like a set of Edlebrock cylinder heads!}
