Cool vid, thanks for sharing.

Seeing the process makes me wonder how durable the big bore LT5 engines are compared to a stock bore engine? There must be a lot of work into making the 415/427/441 inch engines. And mega amounts of money.

peace

Lee,

You are heading for a record with the longest lasting thread, if not already the winner. Many of us have been following this for the past 2 1/2 years. I can say that it definitely helped me while I was building my motor in my garage like you. Thanks for sharing all your trials and tribulations!

Craig

Bad day today...


The bearings I am using were recoated by Calico....original to the car. Went through torque/angle on all of the cradle bolts, and the crank is locked.

Did some testing.....2,3,4, bearings are locking the crank.....replaced the recoated thrust bearing with a new OEM and crank would spin as long as 2,4 were not torqued down.

Seems odd....any thoughts?

If everything mic'd ok and all bearing sizes checked out and crank checked out, it doesn't make sense??????

Has the crank ever fell over while standing on end? I've seen them bent from this. Doesn't take much to do this.

If the crank is not bent, would it make sense to use shims on specific caps? (given that the crank is straight) We do this on every six cylinder used on my 53 restos.
