when i took apart my project motor(B18A), i noticed that each main cap was a individual piece. While i was screwing around in the junk yard i came accross a B18B lying half in a car. I decided to take it out and check it out. I noticed that the "main caps" were all tied in together kinda like a girdle.

Is this how all B18B's are?
And is this better than the A setup?

anyfeedback would be great!
