A couple more pics that were supposed to be in the above post:
#1 shows the heavy duty block webbing around the mains, giving the motors their reputation for strength.
It also shows how the block skirts extend well below the crankshaft centerline, hence the name,
Y-block. Viewed on end especially with pan in place, they resemble a letter Y, as opposed to the
V of the SBF and SBC.
#2 Front of motor where timing cover is bolted. Stock timing covers are heavy. I will be putting my aluminum
cover on though. There is a simple pan that goes on top of the valley, with an airspace between it and
the bottom of the intake manifold.
#3 4 of the solid lifters installed. Motors never had hydraulic lifters. Flat tappet lifters, and their
matching cams, have been failing with high frequency when the SM grade motor oils are used, due to
the additive ZDDP being removed to extend catalytic converter life. Most likely will be running GM oil
additive EOS on each oil change. It has lots of ZDDP.
