gobs of torque down town, tons of mid and enough top end to chooch. will run on 87, has great street manners, easy collection of parts that are all reasonably priced. no bag o' tricks necessary for assembly.
Ugly cam idea, except the split duration which I tend to favor.
With the Magnum head with the 1.92 intake valve should see a LSA of 106.
Find flow test sheets with the stock Magnum head and realize where the head flows levels out and drops. When I say drop, I really mean like falls like a stone. Some high lift flow loss will happen.
Lift the valve as much as possible or reasonable. It adds a few more HP. Is it necessary? No, but it helps.
