Stroker or Not

I thought maybe that's what you were meaning. I'm not familiar with the KB243's but I'm surprised they didn't stick out a whole bunch being their for a 3.31 stroke. Yeah if you shop around you can sometimes find a good deal on parts seperately. That's how I did mine. Took longer than just picking out a kit but I saved a couple hundred bucks and got just what I wanted.

Sorry,I only used the surface area volume on both charts so the calculator read it as the piston would travel down further and come back up with more air pressure to give it that much more compression.To get under 10:1 the piston would have to be in the hole some(don't want to guess an amount and be misleading).I did my test with 66 cc heads and those pistons were .018 out of the hole.
