thats like the cam i was looking at but my "old timer" said not even to bother! im running a .510 lift "340 lobe" [email protected] dur with a 108 LSA. i know the slants like a 104-108 LSA for most any cam. and i hate comp... JMO!

also my tq curve was amazing! i had 200tq @2500 and was climbing till i let off! she really wants to keep pulling past 5K i imagine at least 6500 but i want new rods and pistons first!

I have no problem with Comp at all, although I think their power range is overestimated and their compression requirements are lower than should be. I have to run a cam with at least 112 LCA due to my fuel injection requirements. OBD1 is quite forgiving but OBD2 is a different story and OBD3 is an entirely different animal. I still have to pass emissions with this so that is another parameter I have to keep in mind.

Although both engine are essentialy I6's, our build parameters are quite different in regards to displacement, induction, rpm capability and performance requirements. I could drop in a 4.2 AMC crank and have 4.5 to 4.7 liters of displacement. My vehicle is also 4WD and needs a broad torque curve. A 108-110 LCA would be great but with FI and my emission requirements, it aint happenen', lol!

You've got a great build going on and please keep us all updated! I know that Memike will really want to know about your present build. BTW, it sounds kick ***. :) I've never heard a L6 lope like that before and puts the sound of a BMW E46 I posted on another thread to shame.
