For what a new motor is going to cost you in time and money you could get another 04 and use your old one for parts. It is a buyers market right now. Just sayin.

 

my brother Ed's fat boy did this same thing. he didnt have near the mods that you have, but he rode his like he stole it, every time he swung his leg over it. the MoCo rebuilt his under warranty using his original bottom end. dont know if it was the right thing fo rthem to do or not, but it ran hard for another 20,000 miles before he wrecked in June 2005.

I just read for bout 5 minutes on Ur choice of builds.. Wonder if U did a lot of homework on it.?.
The 264 cams don't even come on till 3500 rpm (with their 60 Intake close) and if U build a motor for always running in the upper rpm's I sure wouldn't want that in a B motor, not meant to wind a B motor 6k all the time.

Most who own a 88" motor knows that the tensioners are the weak link and with all the extra pressure those 264 cams and SE valve train put on them they'd for sure wear out sooner.

Could it have been tensioners wearing out putting a lot of particles in the oil then that leading to bearing failure like most of the other 88''engine failures I've read about in here.?

When U say no cam bearing up grade, do U mean they didn't change the bearings at all on the build ? or used the ones in the SE Kit.?. Because If I remember correct the SE cam bearings are the torringtons. So there wouldn't be any upgrade..

As far a the crank, for sure get it check by someone who know what their doing. I'd even make a few call to the better builders out there.

Every article I've read on motor build that net over 100 hp always say the bottom end needs beefed up.. not sure Urs had anything done to it.. sounds mostly top end.
