1936 bearings

[Lyle]

The late model 36 engines having inserts are marked LB* Where is this stamped on the block? I do not have the engine apart.I would like to know if mine is Babbitt or inserted without taking it apart Thanks Lyle. Hot here some where in Texas.

"If" it is stamped it will be on the front of the intake manifold mounting surface. Can't remember if it is on right or left side. I have a '36 LB engine that is not stamped with an LB, so not all are stamped. Two ways that I know to tell an LB are to measure across the front outside area of the oil pan near the front main bearings. This area was widened ~1/4" for the additional width of the LB bearings. Also, it you take off the oil pan you can measure the distance between centers on the main brg journal studs. Poured bearing studs will measure ~3" and and LB will measure ~ 3-1/4" center to center on the main studs. JM

LB-

Be super careful about the marking "LB" which (if found), is on the left intake manifold deck near the water pump. Unfortunately, some engines have the LB stamping and ARE NOT a LB engine. It seems some "low lifes" have no problems stamping a non-LB engine as being a LB just to get the high buck. The only sure way to know what you are buying is to pull the pan and do some checking.

Having just done one of these engines, I thought I would share my experience with bearings. The main bearings were available, but the flanged connecting rod bearings used in the pre-'37 engines were very difficult to track down. Even though they are listed on a lot of websites and in a lot of catalogs, when it came to ordering I found that they were 'no longer available'. And this was after I had the crank ground and some other machine shop work done on the block. I waited to order the rod bearings until after I knew what undersize to order.

So before spending a lot of time and money, it might not be a bad idea to source out the connecting rod bearings first.
