Re: Project Never Ends
On the positive side, you didn't wrap the rods around anything so it's entirely possibly that a crank grind and bearings will get you mobile again.
Possible a cap popped out of one of the galleys?
Was it an all of a sudden pressure loss, or did it gradually get worse?

We'll be on a tight time frame (wife and 2 friends coming along), but I'd love to grab a bite if you guys get a chance. Maybe Sat night? PM me a cell #.

Re: Project Never Ends
Crossed my mind but I highly doubt it. I think we got bad info from the hone guy on proper main torque setting and I went with what it should be.
Won't truly know until it comes apart. Part of me thinks it is rods as that is only thing that didn't get machine work done to them. But might be hard to tell what happened first.

Re: Project Never Ends
Several weeks ago I pulled the engine out of Heather's Ty. We knew the snout of the crank was bent from the moment I started it (2yrs ago) after the build.She drove it for 13,000mi. I verified with another ballancer that the snout was bent. Now that it's apart.. I had the crank checked and it's over .18 bent on the snout. .08 in the middle and .05 at the rear. THe crank spur gear did not even contact all the way around where it contacts the crank!
Anyway.. despite the obvious crank issue.. I think that a HV oil pump sucks the pan dry at high rpms. Unless your using a deep pan and pickup with 7qts I think a standard non HV pump would supply plenty of oil with out pulling it all out of the pan on a pass. I wonder if your pulling the pan dry on full passses and tearing up the bearings that way...
Just a thought,
Scott.
(Bummer total bummer dude.. I thought it'd be done for awhile this time)

Re: Project Never Ends
I run a 327 on a HV pump with stock pan and I dont start to empty the pan until about 7800 rpm (that is when oil pressure starts to drop) and I am not running oil restricters I did plug the hole in the lifter valley, opened up the oil return passages and polished the lifter valley and I have and windage tray

Re: Project Never Ends
It is a short stroke small block no power adders(except for rpm) and the only thing stock is the pan

Re: Project Never Ends
Been awhile since I updated this.
Pulled the motor apart after it had issues at the shindig. The 3 center mains were TOAST, as in all copper, 1 copper was half missing even. Whats odd is the front and rear main looked good (minus trash that went through) and the rods looked almost new. Starting to wonder if it is all oil delivery now, or the crank was bending. It was bent last time.
1 way to solve that is a forged crank going in, 4 bolts splayed caps going on, main girdle, h beam rods also.
Going to make the stock block as strong as possible.
This time engine will be run on engine dyno by a well known local builder to check for oil flow, etc. Be done without turbos but should give me good oil flow idea.
Going to send the pan out to have a new one made in aluminum. Probably throw some new valve covers on also.
SFI flexplate and balancer going on this time also.
More to come,

Re: Project Never Ends
Crank/rods are all done and balanced. New ATI balancer this time also.
Block was in the align bore machine yesterday and should be done today, probably pick it up tomorrow with hopes to have motor mostly assembled and a new oil pan built by end of the weekend.

Re: Project Never Ends
Yes we have. Going to check EVERYTHING in the block once again (Jeremy is helping and does ~3 rebuilds a year for his race car also a SBC).
Engine going on a dyno this time also for breakin, minus the turbos.

You're gonna let a guy who has to rebuild his motor 3 times a year have a look at yours?
