36 ford
What does LB stand for when referring to the motor and do you have to remove the body to replace the floor from the seat area forward. Thanks, Charles

Re: 36 ford
LB has also been thought to stand for large bearing since the insert bearings are larger diameter than the poured bearings. Ford literature lacks a definition, so LB can stand for whatever you want.

Re: 36 ford
I believe the oil pan is slighty deeper at the front to clear the larger main brg.

Re: 36 ford
I always thought the oil pan was a little wider at the front on an LB. Some LB's are stamped LB on the surface of the block where the intake manifold is bolted. Some non LB's may also be stamped similarly by dishonest folks trying to make quick bucks. The best way to determine an LB engine is to remove the oil pan and measure center to center distance between main bearing studs. LB = ~ 3.250" and non LB = ~ 3.000". The absolute proof is to remove a main bearing cap and confirm that bearing is loose/removable. Some of our Australian and New Zealand friends (maybe Canadian as well) have reported having a hole in some area on front of block that signified an LB to them. I have never seen a US manufactured block that had that same hole.

Re: 36 ford
It has been written up in several books/articles that generally speaking the insert bearing LB engine, came out in mid-year '36, however, Ford had an abundance of babbit bearing blocks still in their system so they continued to use them.
I believe that I have read that the babbit bearing engines continued throughout the '36 Ford model run. As stated in the preceding threads, the sure way to find out what engine you have is to open it up.

Re: 36 ford
i agree with Charlie. If you have the original heads on your engine you can tell pretty quickly. Domed pistons first came out with the LB engines. If you have an LB engine the heads should have a 48 part number prefix, Flat top pistons would have a 40 prefix.

Re: 36 ford
I have an original never been torn down (until I removed heads), '36 Ford LB engine removed form an original '36 1/2 ton PU, w/original 3-1/16" bore, minus some slight wear, that has flat top pistons. Heads are only marked with Ford script logo. No part numbers. The truck was purchased from the original owner who kept this truck on a farm not far from Baltimore, MD. Some pictures are attached.
