The crank had more clearance last time and I now have a new eagle crank untouched.

The raised hole.001 or whatever it is is only effecting the top half and the lower half is fine so I know the crank is ok.

What was the #1 main clearance at on this build?

I have a real hard time seeing how that oil hole was "raised" all along and didn't cause issues last time?

The other crank had a .010 under bearing and about .0035 to .004 clearence so this crank mic'd to speck,I put std bearings in and ignored the tight turning being in a hurry.

The thrust was tight so I figured it was that.

If you have too much bearing clearance, you will know. If you have too little clearance everyone will now. Nothing the matter with .004"mains. What does the the "thrust tight" mean?

"thrust tight" mean?
I hit the crank forward and back and it was still tight.lol I think it checked at like .004

If it had .004" endplay what do mean "it was tight,lol"? Did it feel tight when rotated by hand?

Yes it was tight turning the crank with no rods or pistons in it so Yes I screwed up by going ahead.I should be able to get it line honed and get things moving smoothly.I hope the other mains did not mess up the crank so it can just be polished.Wait and see how things work out I can use these to help maybe.What do you think?

would hold off buying any parts untill the machine work is done,then discuss it with your machinist.

I second the waiting on parts. We all live and learn. Good luck, hope she comes back together nicely.

I know to wait on parts.I wanted to start discussing when to use those parts as long as I have your attention now.

You certainly do have our attention. I at least speak for myself and hopefully others, that we dont want any fallen Mopar brethren.

So this raised spot that every main has by the oil hole, is this from machining/drilling the oil holes/galleries on the mains, almost like a burr? If so you might not need an align hone, hitting each with a radius'd small hone and working them out by hand might suffice. Id think bad main alignment would've even should up with the looser clearances? You take away .001 to .0015" and now it's to tight? I'd get rid of the burrs (if that's what they are), polish the snot out of the crank and get your .004" bearing clearance back.

Maybe some dye on the area and rub a bearing across it to check or partial bearing with emery cloth lightly.The oil hole is drilled from the crank to the cam so why it is raised idk.
ps:the bearing is black for 3/4" on both sides of the oil hole with some along the 3/4 groove on the trailing edge.[fyi]

when drilling a hole, no matter how sharp the tooling used, there is a burr raised. it may be very minute, but it's still there. that is why deburring both sides of a hole is good practice.

Being you had a crank in this engine before and all was OK - I am guessing your clearances were a little too tight with this crank - did you check the crank for taper on that journal? - Eagle cranks can be all over the place as far as clearance from journal to journal. I would find it hard to believe that the oiling hole was drilled after the original line hone was completed - but stranger things can occur

When you set your thrust bearing did you do it before you torqued it down or after - that might explain your tight thrust

Thank you for your help on this Everyone!!!Roush did the machine work on the as cast block and as in the past with the oil hole in the cam it is high so if it was honed it did not take it out.I set the thrust after I tq'd the mains.I only did a quick check on the crank and the shop that balanced it I guess never looked.[not that I asked]I will go over it better now[a little late I know]
ps: the killer is I asked the engine shop that honed the block to align hone it and they did not want to.[long story]
