No Worries,Thanks for the apology. No big deal. I have a 400 block,I have a 71 340 block and forged crank,also have a complete 440. 451/stroked 400 using 440 crank and rods fits A body better. #40,cause I have options. 440 wasn't brought up cause I've built a few and know what they can do. Never used a mopar overdrive 4 spd. I have some regular 4 speeds. Lookin for a less expensive route than a gearvendors,thats all. Never used a mopar overdrive. drove a couple on 318's that others owned. They had round shifters on them that were sloppy. Didn't know if the pistol grip shifter would work on one. Although it sounds irrelevant if the OD won't take the abuse. Researching before spending. When younger I did it the other way around. Little smarter now...
