The Crane cam seems to have a bit more advertised duration then the Comp Cams offering
Comp Cams
XE270 which is 218/224 @.050 and 270/276 114 LSA .544 .544
http://www.compcams.com/catalog/156_157.html
This is from the Crane website
Cam Specifications for the Power Max
220/ 226 @.050 and 282/288 114 LSA .529 .544
http://www.cranecams.com/master/apps/ford18.htm#1.%
20PowerMax
Looking at them it would seem the comp cams would work better and be more efficient. Any opinions??
Thanks
