Like Lynn said if cranks too fast will pump big,had pulling customer pumped 481 with a 468
he had old delco hi torque with big dozer battery,they then pulled head and measured bore and stroke and could'nt measure stroke correctly they measured 4 1/4 so customer wanted to know if we could have ground crank wrong, no can't grind crank .010 and add 1/4 stroke,LOL ,we tested later would pump 481 could put in gear and let clutch out enough to slow cranking speed down would pump 468 then, when cranks too fast first hit of compression it blows the piston up farther than should.
