That's one of Crowers level 5 cams.
I think a level 3-4 one from them like the 31243 would be better suited.
This is a dart sport with 3:55 gears used for street and strip with power brakes ?
Bruce,that cam ,is a generic low dollar copy.Spend 20 bones more,look at a Crower "Ultra Beast",grind number 31916. 269/282 advertised,223/234 @ .050,..480/.494 lift on a 1.5 stock ratio.112 lobe centers.If your actual compression around 9:0 to 1,idles slightly rougher than a 340 cam. With some bowl ported heads,goes crazy. Simply a better cam ,seen four of these cams run,2 on my own part. Sorry about the post length....
