The reason I ask is,I was wondering what you used for an installed centerline? I tested an older version of the MP 4120657 camshaft in my 421. I played around with the camshaft timing to see what it would do. This was an older version,312-106 that has a .404 lobe lift instead of the current design. I know a lot of people say to advance these camshafts a lot more than the MP recommendation, but with mine,it lost quite a bit of power past 104 installed. Every engine will be different,but I just thought I would pass it on. Keith
Any info on the current design? I just installed the current .590 to try out and installed it on a 102. Will keep ya posted on what it likes.

I've genereally found if the port cross section is relatively small compared the the cylinder swept volume (as is usually the case with a lot of wedge strokers), putting the cam in later helps the top end power, also an under-ported motor (if it has any decent compression) generally has an abundance of torque to begin with.
Advancing the cam generally works well when you've got plenty of port, adequate cam and compression but you're wanting to "use it all up" within a certain RPM limit.
