I have serious doubts there is anyway to move more than maybe 2 quarts into the upper regions of of a SBF, before it's flowing back into the pan(most of the oil is flung from the crank so is immediately flowing back to the pan)... Maybe below freezing or some ridiculous RPMs but most street engines will have grenaded themselves by that time... Mine has approx 700 drag strip passes, idled 50psi hot and approx 80@6000... Yeah that's high but it came in the rebuild kit so is what's installed... New 331 will have a std pump...

Just a thought!!! The DIZZY gear in the SBF is marginal at best. The 2.3 guys like myself know this so well. Using a HV pump is not necessary if the bottom end is built correctly. Their is a big difference between HV and HI PRESSURE. Either way HV and or high pressure pumps are a scam. And their is absolutely no need for them. Your DIZZY and oil pump shaft will love you for using a stock PUMP!!! Just saying!!

Hey guys. Loooong work day yesterday. I went to my friend's house and picked up my hoist. Waiting for the temperature outside to come up a wee bit. It's 33 degrees. Once it warms up a little I'm going out to pull the engine.

As far as the oil pump goes, my plan was to stay with a stock replacement. I never used a High Volume pump before.

I'll be reporting any findings I come up with once the engine is on the stand and in the garage being torn down.

Not how I wanted to spend my weekend off, but, gotta do what I gotta do.

when you do finally get he rod/mains out, look at them under a magnfying glass.

plasti guage at the 12, 6, 10 and 2 o'clock positions of the number 1 main and rod.

what i am getting at is that you may want to have the mains / rods broached. so you have brand new perfect round holes in your block and rods.

out of round block / rod caps are not that hard to find in a hi mileage block.
from there, a crank can be turned and matching bearings can be had so that all is round and clearanced correctly.

what they do is take off about .005 in' on the rod caps , then they put the caps on the rods then they machine in a brand new hole perfeclty round.
same process for the mains but there is a process by which all mains are puched back out in one pass so all the mains are linear.  its not that hard to find an iron block that is twisted enough such that the orientation of main #1 could be out of alignment with main #4 enough that it effects actual gap.
in a perfect world these crank journals must be oriented perfectly to keep the oil clearance gaps geometrically machined.

good luck,, time you try gapless rings to??????

The engine is in the garage now....trans mission is on the floor, and all parts are on the benches. I have a butt load of zip lock bags with all of the fasteners labeled and waiting to go back where they need to be. I'll have details tomorrow about the rest. Tired and cranky, and want to just sit down and watch Velocity for a while.

this has gotta be depressing, all the work you have into this and 30k later is pin out on you.

not sure what to say but the sludge you found would have to force me into a motor tear down as well.
good luck man, keep us up to date.

Will do. I have to say, no sludge, just some gray oil in areas. I'm thinking bearing failure. Glad I don't spend anything from my paychecks on this car. Tomorrow I'll have answers and a solution one way or another. Going down in the morning to the local Autozone and grabbing some gaskets, loctite, and getting busy. I was looking for a clutch disc here in town, but they only have the full clutch kit. I don't need all that. One of my friends is coming over to help tomorrow, and he is the commercial manager at Autozone (sells to businesses), and I'm betting he can get a disc for me. I hope so anyway. he deals with the outside aftermarket stuff.

Anyway, I'm looking forward to getting this finished. Hopefully, if all goes the way I hope it does...(and really I don't see why it would...LOL),the engine and tranny assembly should be back in Wednesday. Giving me Tuesday to button everything up. Maybe tomorrow evening as well depending on when we start and finish.

Updates as they occur.

I can't say I'm depressed, but just weighted down by it. If that makes sense at all. I'm ready to get this  done, and move on to other projects for the car, like getting ready for bodywork. This depleted my funds for that quickly. Oh well, it always seems to work itself out in time.

Vinnie,

Are you going to have someone look at the crank or did you come up with a known good one?  Typically a bearing failure will get the main or rod bearing surface on the crank and it will have to be turned 10 or 20 to clean it up.  With a manual car I would strongly suggest that you stay away from the Clevite 77 "P" series bearing as they are too soft.  My engine builder and machinist both recommended the Clevite 77 "H" or "V" series bearings but both said the "H" would be fine for my application.  These bearing are a little more than the "P" series but what's $50 more versus tearing a motor down?  Anyhow, the one thing you have to make sure you do is check the thrust clearance on the center main bearing.  There are several good reads on this such as:

http://forums.corral.net/forums/5-0-5-8-engine-tech/1184679-assemblying-shortblock-2.html

Pay attention to Woody as he is an engine builder and knows his stuff.  The reference to setting the thrust is on Post #58.  From there you can research the hell out of it and see what I am talking about.

Well I am off to the garage to paint the block so I can get started on the 331 assembly.

Well, the engine (short block) is back together and torqued to specs. Bearings looked like copper. That was probably the grayish stuff in the oil. LOL. New moly rings and bearing installed. Tonight after work (if I'm not too tired), and tomorrow I'll button up the rest and do some cleaning, and HOPEFULLY on Wednesday, I'll stab the engine and tranny back into the car. We'll see what happens.

More updated news later. Gotta get to work.

Just a question??? Did you use another crank??? If not did you plot out the readings??? just curious??

what do you mean technically when  you use the term "plot",, is is similar to what i was saying about checking various points so you can determine out of roundness to journals or block?
