Usually engines are balanced in grams. Big difference between oz and grams..

Really I hope that figure of 15 oz was a typo. That seems like a ton to me but I don't build engines of that level it might be normal.

Probably grams, I don't know. Thought I heard Oz's but yea that seems like allot. Trying to remember now what 15oz vs 15g of weed look like. LOL
Half a bag of weed.

15g get me high a few days. 15oz gets me high a few months.Half a bag of weed.
Not that I indulge much anymore...But there was a time!

Torqe convertor,drive shaft,rear axle,bent wheel....probably not something in the engine unless its fuel or ign related

could also be harmonic balancer...does it vibrate in first and second?????

Got an update yesterday. Crank was out 34g on the light side. Rings were washed out and moly was worn off. Cam was degreed at 109 IC in the block (at the lifter) but at the valve was 112. Everything else was perfect, LOL
Plan is to balance the crank, Hone the block (Slightly ) for new rings, Reassemble everything and (While we didn't talk about yet) get it on the dyno before sending it back....
So far INDY's been pretty upfront and taking care of business, I commend them for that! They never denied reasonability and promised to make it right. Only thing is they are taking their time with it, probably wont see it till January. I have hope.

Could someone explain how a cam could be at 109 at the lifter but 112 at the valve? I don't see how that's possible (i am not smart though)

The way it was explained to me is, at very high spring pressures, the tolerances of the lifter to the bore (side load), Lifter to push rod, pushrod deflection, rocker shaft bearing clearances and basically all the stacked tolerances in the valvetrain act to retard the timing at the valve more than at the cam. INDY says they do an initial degreeing to get it close, then verify at the valve once fully assembled, and make any fine tuning adjustments as needed. This is provided you are running a belt drive. They add a few degrees on a chain initially knowing this will happen. This is how it was explained to me....

Sure Hope you don't trace the vibration to the rotating Assembly after all else eliminated....Shaking fenders & Interior sounds pretty far off balance.....Having to pull engine down for Rebalance would be terrible ....If all fails to correct & With nothing to loose, could some "Trial" Weights be temporary placed to various positions on Flex plate and/or Harmonic balancer to get improved or acceptable smoothness ??

It was the rotating assembly, The motor is out and sent back to INDY a month ago. It was confirmed!

Add 200 grams to your 30 and thats how far out my hemi was.. its was horrible
Wow what a **** show this has been. Should never have been an issue to start with and you’ve handled it far better than most of us would have. Hoping that the entire second time around is on their dime including dyno time to ensure it’s right this time around.

Thanks for the kind words. Yea I'm not happy about it, but I figure at this point its better to be nice as I will need to deal with them in the future. I would hope they are covering the rebuild, Dyno time, And transportation both directions, We did not discuss any of this!. I'm just assuming at this point. BUT if my assumptions don't play out I will have to change tactics.....So far they are taking full reasonability. Believe me I will let everyone know how this works out.

They had motor since 9/27. I ask for an update on 1/2, was told " no real progress yet---- except everything is corrected----and ready to go back together----we will fit it in the best we can-----thanks kenny" WTF do I do with this? Why am i being (FIT IN) IMO I should be the first in line!
This was my answer:
Kenny, I think I've been pretty fair, understanding, and mostly patient. You have had the engine for almost 14 weeks now (3.5 Months). I understand I did not buy a fully assembled engine, but I did pay you almost $30,000 without question. I think we both agree that the issues were preventable and by no means my fault. It's been over a year that I pulled the trigger on this engine thinking I was getting the best of the best. I am a patient man but my patience is starting to wear thin. Please do your best to move this along. I understand things happen and I get it, BUT I would have thought I would have been taken care of as a higher priority given the circumstances.
Was I out of line or you think this was an acceptable response?

You have been more than patient with them but it's a fine line between being firm and rude so choose your words carefully on your next discussion on who's going to pay the freight this time. I have heard they don't move things along in a timely manner for small clients. You may have to make a road trip and pick it up yourself to start a fire under their asses. I have to do that with Liberty Gears when they have my parts, I'm always behind the pro-stock teams in order of shipping so I just say "I'm coming to pick it up ready or not"
