boring the 292 truck block to 4.00 inch diameter; using 256 merc crank with 3.10 stroke; using 6.252 rod length which yields 2.01 R/S.
This should produce a 311.6 ci displacement hence approximately 312 from a little bit different direction; also, this yields a Bore to stoke
   ratio of 1.29. what is best piston to use?
