Help with cam choice for magnum 360 please

One thing to keep in mind is with the poor lifter to pushrod angle inherent to a SB Mopar you loose .020-.025" lift even with perfect geometry. I always heard that and last year I did a mock up with a couple different cams to see if it is correct and it is. My test used 2 different hydraulic cams with the lifter blocked so as not to loose any lift from compressing it. With roller cams the lifter to pushrod angle is even worse so you'll loose a little more. You really should measure your heads to see how much lift YOUR heads will accept as manufacturing tolerances vary. Turd might measure his at .500 lift max and yours may be .480 max or they might be .520 max. Can go either way. No matter what cam you use you should measure to determine what length pushrods you need because again manufacturing tolerances vary so much there is no way anyone can say that a certain pushrod length is the correct length. Another thing I noticed you mentioned using 1.5 rockers on your heads. The only way you can do that is to convert it over to Chevy style stud and ball rockers because all rocker arms made for Chrysler magnum heads are 1.6 or 1.7 ratio. At least all I ever saw advertised were and I went through that last year trying to find some 1.5 rockers for a set of magnum heads. They didn't exist then. I have been burned a couple times on E-bay so I'd be leary of ordering a cam from someone there. If the place is a legit business they should sell to you direct. If I were interested in the cam like you are I'd e-mail him and ask about buying it direct. Paying a business with a credit card generally gives you protection that you don't get on e-bay. E-bay claims you get protection through PayPal but don't believe it. I bought a part from a guy and payed with PayPal and the guy never sent the part and PayPal tried to collect it from him but he drained his account before they could collect so I was told tough luck.
