Im looking at a new brand cam that cam out for the 400ex called a Hot cam they have funny measurements though.The duration is 254 on both the int.&exh. and the lift is done in mm's it is 8.8 on in. & 8.6 on the exh.Does any one no what that calculates out to in inches Im trying to compare these cams to some of the other grinds out there.If any one knows how to convert this let me know what you come up with these are supposed to be drop in cams and you have no core charge and no need for hard faced rockers they are billet cams.THANKS for any reply.Oh they are only $140.00 and like I said no core charges.

Your R.P.M. range is set by duration. The more duration the higher up in the R.P.M. range your power will be.
