Wow thats really obvious that was not done by GM... Defently have the shop make sure everything is good with it and have it balanced. Unless you want parts to be breaking on the bottom of your engine from improper balance....

 

If you want another option, I have two (2) totally stock LT1 cranks sitting in my garage right now. For $50 you can have your pick of one of them.

 

Raroz28, I replyed to your PM with additional info. Let me know what you want to do, okay.

 

Thanks a lot Ken, I appreciate it

 

You're welcome!

 

Got a crank from Ken today and it looks just like my stocker. Quick polish and it should be good to go.

And I installed a new pilot bushing as soon as I got home so I didn't forget

Pleasure to meet you Ken, wish I had my Z28 up there with you earlier! Hopefully we will meet again at a get together or maybe the dream cruise next year.

Thanks!

 

You are very welcome, and it was a pleasure to meet you also. Best of luck with the re-build too!

 

It's going smoothly so far, just gotta get some extra cash to get it into the machine shop.

I called Hastings about those rings and they are not file fit, which would explain why they're all within spec already.

 

Yep, just as we discussed last evening, file fit rings would NEVER be that "loose" to start with ........ another engine building "mystery" solved!

Also, don't forget to "de-carbon" those piston tops with spray GUMOUT, and de-burr the piston skirts, as we discussed also!

 

Yeah I actually took care of the pistons with a fine file yesterday. It came out very smooth and without burrs. Only one of them was nicked up, the rest were OK.
