IMM Engines 408 build

most of the changes seen are based on when the intake gets closed
narrow LCA can close earlier than wide LCA depending on Intake center line installed
one crutch is to advance a wide LCA cam (or a too big cam) but this has side effects on the other events
best to get a cam with the correct valve events in the first place
the narrow lca cam may not have been the correct cam either (power falls off early, horrible gas mileage, exhaust runs hot, etc
all tradeoffs- choose wisely my friend- who said that?
