Progress tonight was more than planned.
First off..there'* many signs that this motor is a remanufactured. Valve seals for one of them, the cleaniness of the entire motor and the paint marker. I am in high spirits with this information in hand.
Some clean pics..
Some of the paint marker stuff
Balance shaft machining isn't filled in at all
How I am treating this jem while working on valve springs
The valve seals I found...these aren't GM factory seals
Rocker difference..here'* a rocker off the last motor near the new rockers.
I did the rockers, springs, cam, oil pressure increase kit, oil pan and intake. It'* almost ready to go in....oddly enough it looks much like the last couple.
My redneck cam install tool
It'* funny...it felt wrong to take this one apart to add the better parts because of how new it was inside.
Casting difference is noticable in the intake area...on the ends the gaskets have locating holes for the end pieces. On the 97, they weren't there..the 01..they are there. That'* about the only thing I noticed.
