OK you know that a 727 will take out your 8 track if you do burn outs in first with a manual valve body--Right? The sprag fails and BOOM! I have done it--most Mopar racers have done ONE--but then we learn--OK..here is what happens when 727 explodes--shoves engine into radiator--this 440 was finished and sent out a few weeks back--it ran GREAT! Made some good HP with Sidewinders and .509 ( yea..the ole good one) during recent burn out "stunt" trans goes Pow! and customer advises engine has a tight spot now--OK bring it and we will look--HOLY SMOKES!! Yanked the pan and here is what we found

ive seen a steel ford crank do that, but never a mopar big block.and the occasional cast sm block stroker crank.but thats what them sm block guys get when they race with a 300 dollar crank.thats one place i never buy cheap,i use winberg.they are truly a work of art..
SFI 25.5 depends,no leak,even at 213 mph....

I spun a rod bearing in a 426 wedge and it ran but would not idle My fault, I just got the car and it was low on oil Unfortunately that is the hard way to learn, but you never forget. Every time I break something I learn something new.

I have a crawler-loader that has a 4 cyl diesel in it... I broke the crank in it right under the #2 main bearing.. I did it twice the same way.. it would just loose power and a minor knocking... the main thing it was a MAJOR PITA to get it fired up.. basically it turned into a 2 cyl engine... I found out later that the previous owner blew the head off the engine using starting fluid.. I believe he cracked the crank and bent the block

Trans was not our doing. The new one is. Well known brand three letters TURNS to CRAP INSTANTLY. New trans has a proper Griner Low band apply valve body and good guts. Motor mount was elephant ear type. The motor shut off instantly when it popped. Barely nicked the rod. COULD easily been a total loss. Todd
