Hello all. Name's Mike, I'm from Alamance cty Nc...I've always loved Hondas, have owned a few and recently, finally got my "white whale" 91 wagovan...problem is, there is no engine stamp...it just has a 6 digit number and HM....this is bothering me because I was told It's a B18c1 gsr motor and tranny...any help on this would be greatly appreciated. I look forward to reading through forums and learning even more about these awesome machines. Thanks in advance - Mike
