My crank went soon after doing a 107" and t-man 555tq cams. It's not unusual for it to happen.

Any time you bump up the compression and overall performance parameters of the motor into the 110-120 hp. and tq. range the crankshaft and rod bearings then become the weak link in the chain. There have been many posts discussing this before.

You should cancel the remaining ESP contract and cash out that money can go into rebuild.

Sometimes we build what we want and are aware of the possible consequences. Sorry your luck ran out this time but Kudos to you for knowing the difference between bad luck and "The MOCO screwed me!" Have the bottom end redone with a welded crank and timekin conversion and enjoy the ride.

Thanks friend. I've never really considered lower end issues till now. I'm working on some options with some local talent. Did you move from Sac?

i lost a bottom end this year as well. Dark horse has a 4-8 week turn around right now ..... i ended up purchasing a crate motor and will build a spare over the winter. Hope things work out for you.
