Quote: 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
I'll pass this on as well since we're in the sharing mood... Our engine we just did liked straight up best. This was on a 112lca. Brian
