If a 1936 engine has an LB marking, is it visible with the intake manifold installed? Is it always at the front of the left bank?
 
On the ones I've looked at, the LB marking is visible with the intake manifold in place - front of the left bank....
 
I have 3 lb blocks, none marked---- perhaps the oil pan can tell by shape or hammer dents out to clear front main bolts
 
I have a LB engine in my '34 PU. There are no marking (LB) stamped on the top of the engine. Another LB engine we have has the LB stamped on the top of the block. Who knows what Ford did? Mike
 
The LB blocks i have seen the stamping on was visible with the intake in place and location of the stamping was near the front but not sure what side.
 
Chris, it's a 1936 21 stud flathead with insert bearings versus babbitt. 36 was the first year that the changeover started taking place.
 
Does anyone know the correct meaning of the term LB Engine?

LB LATE BLOCK ?
LB LARGE BEARING ?
LB LARGE BLOCK?
I’ve heard different people say different meanings.

Another is "loose bearing (s)"

I also have several '36 LB engines that do not have LB stampings on intake deck.

I have heard tthat it means Large Bearing as the cap bolts are farther apart.
 
Okay I hope I get this right but hopefully Brian will chime in to correct me. New Zealand 36 LB engines out of Canada have a hole in the front of oil pan rail about 1/2 diameter at front between water pump & crank seal casting opening in front of block. Very easily distinguished
 
That sounds like the crankcase vent. The venting was added in 1935 which was the same year that the large bearing change came about in late 1935. Water pumps were in the head unless you mean the engine mount spigot for water inlet to the engine.

Main bearing bolt or stud distance apart is the best way to know for sure.
 
It's been said they were only marked with "LB" if the engine was serviced in a rebuild or such after leaving the OEM factory.
