Can anyone send me pictures or direct me to pictures of the 1935 Babbet bearings and the 1936 LB bearings. I think I understand the difference but I just want to see the difference. I am looking at a 1936 engine without the LB stamped on the block. So he does not know which engine he has. All he knows is that it came out of a 1936 car. richardherren@hotmail.com

Pictures won't show any exterior differences. You'll have to pull the pan to view the main caps. Insert bearing caps were larger, having about 3 1/4" between the cap studs. Alan

I agree with Alan. You really need to take off the oil pan to see what you have. The lack of a "LB" stamp does not mean it isn't a "LB" block. Try this (it is not foolproof). Check the part number on the heads. "IF" they have a "48" prefix that should mean the engine has dome pistons and is of late '36 manufacture. This is also the time period that "LB" engines started to appear in production. A "40" prefix indicates flat-topped pistons. A "68" prefix is an after-market head number which may indicate a rebuild somewhere along the line. Caution- as I stated this is NOT foolproof but may give you a start to explore further.

That is what my plans are, to pull the pan and look. I just need to know what to look for.

Measure center to center across studs for main bearings. Poured babbitt = ~ 3.00", loose/large bearing, LB = ~ 3.25" JM
