here's some specs at .004
278/282 198/199 410/412 111LCA Melling 23103 Timing 16-82 61-46 59 ovlp stock cam look where the intake closes I know I know not my ovlp numbers
278/282 197/199 410/411 111LC 2896283 Wolverine CS 4115 and the amount of lift you get with that duration, really long ramps
I threw it into the list so you can see where it fits along with the DC 260
All these cams may be too big (except the Jones) all are at .004 for those doing DCR calcs In duration order
A spread of 20 degrees advertised in the 214-224 range
note how the white box cams come in 276, 280 and 288 flavors for 214-224 cams (copycats)
