Ahh, the mystery continues.

Casting # on the block is 14015443, which translates to a 454, 87-90, 2 or 4-bolt, Mark IV, (Truck, Motorhome).

Block casting date is B039 (February 3, x9, or '89 in this instance.

And the old, crusty, intake serial # is 10052952, according to this website is for a 454, 88 Truck, Cast Iron, Oval Port, Lo-Rise, TBI or Q-jet carb.

All this adds up to the block having actually come from a '89 1-ton pickup - what the previous owner told me it had come out of.

Just another one that snuck out of the plant with the fuel pump/pushrod holes drilled.

I love unlocking the past behind a motor, don't you?
