Stock block plus 2.000 sbc rods, longset stroke?

If you want zero deck for the pistons compression height (CH) : (9.585" - rod length - compression height) x 2

For a 5.700" rod and a 1.500 CH, that would be 4.77". If you used a piston with a common CH for a 360 stroker, like 1.465" then it is 4.84".

Gonna need to do some work to control the compression ratio with that big stroke. Rod to stroke ratio is getting down to 1.2 or less, which is waaaay below the normal range for a car engine. And piston speed is going to be VERY high too and will limit the RPM's to under 5-5.5k if you want to stay within 'normal' bounds.
