I called Mike a Jones and told him I am building a 408 for my 84 3/4 ton 518 o/d with a low gear set and a 3.54 outback on a 31” tire. I will be towing 10-12k. It is mechanical by choice. He told me to put it in @ 109-110

That's a real Mopar intake lobe
CM is Chrysler
70 is 1/4 of the duration 70x4=280 and .325 is the lobe lift
what did mike say for springs?
edm lifters?
break it in right
For those not familiar with Jones numbers the Seat Duration is Seat Duration @.006 net of lash lift not Advertised at .020 or some other lift number that has to be adjusted for lash
So Mikes 280 can be compared with a HFT or HR pretty closely
One thing I can't tell is does mike want you to degree based on the centerlines or on the .050 check at lifter?
Those of you questioning the LCA and ICL need to re-read the OPs build at the top of the page
Mike is great at nailing the correct cam for builders specs
