Well, I belive it's a 216 engine. It's coming out of my 1942 but I believe the motor is a replacement engine built in 1948 and apparently rebuilt by Allstate Engines in year.....? The two center pistons are stuck and will not free. We've had oil in them since October when I got the truck and when I took the head off yesterday for the first time, the oil had seeped through all the pistons with exception of the middle two. The truck had no carb and I believe water found it's way into the manifold and into those two pistons.

The tag from Allstate is a bit hard to read but (I believe) it says RODS UNDEIRISIZE : 020 MAINS UNDERSIZE : 050 ? and CYLINDER SIZE : 040 or 046

So if this was already rebuilt is it even possible to rebuilt again?
