I know, I know... I only get on here when I need help and am thankful you guy's are here.
I am working on a 1997 5.7 LX Alpha 1 Gen II.
The existing motor was pre-vortec and rebuilt by others, I tuliped a valve last year and had the heads rebuilt. After I got it back together I realized it was severely burning oil, assume the rings are collapsed. Decided to replace rather than rebuild and bought a new 5700 long-block from Michigan Motorz and a new intake. I Will be reusing all the original accessories to include Weber 750 and TB V ignition. I am converting to a electric fuel pump as well.
The motor and gimbal bearing have about 600 hours on them, the coupling has maybe 800 hours.
I have a couple of questions, should I reuse or replace the coupling? Is there a way to evaluate it?
The gimbal bearing feels fine and I have greased every 100 hours, should I replace just because I have the OD off (I checked the alignment before I pulled to old motor and it was spot-on).
Some pics for fun..... it was a bit frozen in
