The guy that created allmotorhonda.com is updating his website! For those of you that have Crower Cams knows that the Crower website cam specs are wrong compared to the spec sheet that comes with the cams. I have already gave him the specs for the 62404-2! So we need specs for all aftermarket cams for B18A/B and B20's:

Crower B18A/B, B20
62401, 62402, 62403, 62405, and 62405A(ireally would like to see the spec on the 405 cams)

Also post up specs to Crane Cams(all grinds), Colt cams, Exospeed, JG Engine Dynamics, and any others I missed!

Post your specs here or post them to this thread:
