Speaking of long numbers on intake manifolds, I was cleaning the sludge off the back of my 1969's 302 when I found this code stamped into a brass plate, riveted/glued? to what I would consider the block, but could be the very rear of the intake. It reads "Z 2730 V 128375."
Any ideas? I looked up Ford codes for both blocks and intakes and couldn't find a code that started with a "Z" and looked like this.
That's the transmission to the left and a red/grey intake to the right. Intake is red, block is blue/grey, carb is 2BBL, water pump on passenger-side (if that helps, at all).
