ok so from what i have found standard 292 rod journal sizes are 2.188 with a 3.3 stoke. now if you offset grind to 2.000 journal sizes it is roughly 3.48 stroke. If this is correct that means that by taking .188 off the journal size you pick up .18 increase in stoke. Close to a one to one correlation. Now is this really the case? im wondering as im thinking about trying to stroke my 2.9l v-6 in my ranger by offset grinding the crank from 2.125 rod journals to either 2.000 or 1.8999 journal sizes. im trying to figure out roughly how much stroke that would gain me first to see if it would even be worth it and if i could find parts that are made close enough that i could modify them to work. If i can figure out what stoke i would be looking at i could see if i could find a rod that would work and a piston that would work. thanks and i hope you don't mind the off topic motor but i figure you guys have more experience with offset grinding than anyone else and this general information could be useful to y-blocks as well. Thanks guys.
