Default Re: Started taking apart the bottom half

I forgot to take pics of the crankshaft when it was out and the lower and upper portions of the bare block, but the main jounals looked and felt okay to me. My plan is to take all these components to a machine shop that does some racing engines here to have it looked at by a professional just to make sure I am on the right track as where to go from here and have them check all the specs with recommendations too.

Craig, just posting this link that I ran across when I was looking for header coatings. Figured maybe some one from up north may have some hard knowledge on these guys as they seem to advertise "coatings" similar to what you are exploring?

http://afterburnercoatings.com/

I know I saw a few more links here in our tech section in various motor tear down threads....I think Lee's old thread from his motor tear down had a few links?

Thanks Tom. I am leaning towards Polydyn only because Marc H mentioned he has never replaced main bearings in any of his builds and uses Polydyn. I really trust Marc, but if mine cannot be coated for some reason I appreciate your offer to sell me a set. Wait until you hear about the dream I had........LT5 dream.

Take and clean the mains up with 00 steel wool or soft used green 3m scour pads. You dont want to remove or sand, just clean them up.

I sent my new and used set of mains to Calico Coatings. http://www.calicocoatings.com/

They do a great job too. You can not tell the new from the old set.

Thanks Kevin. I really appreciate the info. What is the best way to store the crank once I remove it from the block. I'm not sure if it is supposed to stand on end or okay to lay down on the side? When I get them back and need to check the clearance with plastigage with that torque to yield and the final if okay will be 3 times torquing the main bolts for a 1 time use bolt. How bad it that?

The Milloin dallor question's.

On the crank, I have heard both side's of the story. I stand them on end out of the block. If they are going to be out for long term ( + years ) I make the 2x6 V cut blocks of wood crate. I use a heavy (cheap wheel bearing grease) give it a good wipe down.

Main Bolts, I think At 60% your clearances will not change. Double check that first.
