i would like to have yall advice, i just rebuilt my 2000 7.3 about 5,000 mile ago and my crank is broke. Im running a custom tuning and stage one single shot injectors, its probably doing about 400 hrsp, im guessing....im thinking to go back with a performance crank but if i do who is the best one to go with and if not would an oem crank work just as fine with the hrsp. I know that there is plenty of people that have that amount of hrsp and they are still on the factory engine. just want to know yalls opinion?
i don't know of any performance cranks out there... just go back with a stock crank. i don't know how the heck you managed to break the crank, but something there definitely wasn't right.
how many miles does it have on it and what kind of condition is it in.....i guess i could have said it different its not like broke in half but it broke on rods 7and 8 it broke around the crank journal
As luke said... check for cracks in the block. i have never heard of anyone breaking a crank in these engines. usually the rods will let go or the block will let go way before the crank does..
It sounds like your crank went for a walk. IMHO I would pull it and have the blocked triple checked for cracks as the previous posters have said. If you have the coin I would recommend a girdle to keep your crank from walking again.
We had one not too long ago that was about 430hp truck break the crank right behind the last main. Pulled the rear cover off and it came with the end of the crank. I think some of them must have some bad cranks in them, should not be breaking at that hp level.
exactly that is the same thing i thought because the block check out fine and im not wondering when it was made it might had a tiny air pocket or something and when i overhauled the enginge and put more hrsp to it, thats when it could not handle it.
WOW that would suck pushin a bit more than 430 h.p wont be sellin my spare motor for more upgrade money boo.
