Mjhoward is at work and he wants to look at it so Im going to check all pistons and see how bad they are.

Im just going to go ahead and get the crank cut down more than enough to clear it so I know for damn sure there aint going to be any more of these problems and get heavy metal added in and rebalanced and be done with it Im tired of doing this ****. One last time

Good luck tomorrow and cheer up man. It will be worth it in the end.
So, if you don't mind me asking, what was the price tag on this for the parts?
I heard 418 were tough becasue of the clearence issues. I like to dare to be different too but knowing that I built the motor is "different" enough for me. Your build has definately helped me learn some about the assemble and in my future plans
Good luck man.

When they get finished with it, you can just pick it up and install it.. that's the way it should be.

There were a few break downs in communication with this. First I was working and Cody dropped the stuff off. The machine shop claims Cody asked him to check the rod clearence to the block, Cody said otherwise but nevertheless there was a communication error. This shop, knowing I was involved probably assumed that I was taking care of all that as I had in the past. I have been working butt loads of OT so I wasn't able to check it out since Cody was in such a hurry. It would have envolved the block being bored and honed, picking the block up from the shop, dummying it up, and then carrying it back to get the balancing and clearencing done. Another 1-1.5 weeks. I wasn't that concerned about it because I thought all the rotating assembly came through Eagle and they had clearenced it. The custom milling on the counterweights would make most people believe the same. Come to find out the pistons never went through Eagle's hands. This is why I will never get envolved in something like this again unless I do all the parts ordering and homework. Cody simply didn't know any better to ask the questions that needed to be asked when ordering. Not his fault at all. We carried the short block back and the shop saw where it was hitting. It didn't look like it needed much and I agreed. He milled as much as he could off the pistons without shortening the skirts which are already about too short anyhow(the pistons only weigh 392 grams). Now they pretty much clear but just barely(less than .008") which isn't enough. .050 would be minimum in my opionion. The shop fixed the other for free and rebalanced. Now the best solution is to take turn the throws and rebalance with heavy metal. We could easily take just a tad off the skirts here in my shop on my milling machine and have the short block back together tonight. That would be so minimal it would not affect balance. Cody doesn't want to do that so it is his call and his money. The heavy metal balance will probably run him $200 more just for the crank.
I hope this clarrifies a little more exactly what the down falls have been and why. There isn't really anyone you can point the finger at. Like I said before, you can't build a one-off engine like this under time pressure. If there is a lesson to be learned from this for everyone on here, that is it.
