Anyone have any info on the following Crane Cams Mech roller Hemi camshafts. R 285/410-8 R 290/446-4 R 286/500-4 R 325 Im almost 100% sure the last set of numbers is lobe lift. There was a post on here several months ago that might have mentioned one of these cams. I would like to pick one that would best fit my application... 572 Hemi, heads flow 460cfm.700 lift, 13.8:1 compression, MP X-Ram.

Found the specs for the following cam also.
R286/500-4 286/292 dur at .050 Lift .785/.760
Opens Closes ADV Duration Intake 51.0 BTDC 95.0 ABDC 326.0 ° Exhaust 102.0 BBDC 50.0 ATDC 332.0 °
Looks like this one has a pretty wide LSA...like 113.5-114....

isn't that normal for a Hemi grind? to reduce the intake charge loss out the exhaust?

When we were running hemi's back in the day, we shrunk the exhaust valve to 1.85", and were going to go with smaller exhaust lobes.

The Crane R290-446-04 is the oldest cam, an early SS Cam, 290 @.050 int and exh, .446 lobes int and exh, LSA 104, 82 overlap, gross Int lift .700, Exh .678. This was generally replaced by the R292-500-06, .500 lobes, LSA 106, 80 overlap, gross lift .785/.760. The SS/DA cam was the R286-500-04,.500 lobes, LSA 104, 78 overlap, gross lift .785/.760. The R296-4778-08 was known as a 4 speed SS/A cam, .478 lobes, LSA 108, 80 overlap, gross lift .750/726.
