High rpm 6 cylinder motor questions.. What's your thoughts??

JohnDeereJimOhio · Feb 25, 2013

Finishing up my G for the 2013 summer and bought a new tractor to start on will be running a gasser Deere.. I don"t have much experience with 6 cylinders and running high rpm so a few questions.. I"m going to run a steel flywheel and cold clutch set up along with a blanket. How many Rpms can I spin safely out of a 4 main Deere block? Will it hold up or should I juste note the bullet and get a diesel block with 7 mains.. Also in a high rpm motor do they hold up better when the bore and stroke match? Say a 4.5x4.5 motor would it hold up better than a 4.5 bore by 5 stroke. Just looking for some opinions.. Thanks in advance..

If its cubic inch limited go with the biggest bore and then stroke to get the rest. Most of the torque is generated from exppanding gases pushing on piston after ignition. . If its wide open on cubic inches by all means go to the max with both.
