So these must all use pushrod oiling now it looks like? I don't see the standard head oiling feed in the block.

I like the cam tunnel being blocked off. I wonder how much power that windage is worth?

Also, it's nice to see the HUGE water jacket holes gone from the front of the deck...



Yeah I like the cam tunnel oil return
I'm assuming the the hole at the front is the oil
supply port like a R-3 dry sump block(they referred
to it as oil pressure, where I would call it oil
supply OR oil IN)... sure looks beefy up in the lifter
