Operating Range: 1300-5600 RPM
Duration Advertised: 262° Intake / 270° Exhaust
Duration @ .050'' Lift: 218° Intake / 224° Exhaust
Valve Lift w/1.5 Rockers: .462'' Intake / .469'' Exhaust
Lobe Separation Angle: 110°

or
Comp Cam
Operating Range: 1600-5800 RPM
Duration Advertised: 268° Intake / 280° Exhaust
Duration @ .050'' Lift: 224° Intake / 230° Exhaust
Valve Lift w/1.5 Rockers: .477'' Intake / .480'' Exhaust
Lobe Separation Angle: 110°

A friend of mine that is a mechanic and professional truck puller suggested I go with the first option since i'm running an auto tranny, but I've got a 400 turbo tranny for it. What do you guys think? they're both the comp extreme energy cam. I'm not trying to build 400 horse, I just wanted to build it up a little over stock since I've got the engine on the stand.
What Cylinder Heads and Pistons are you running in this 400 . If it has Stock Cast Pistons and 882 Heads the First camshaft will be Over stock but very Streetable . If you have Stock Valve Springs they need to be Replaced and your at Max on Pressed in Rocker Studs with #1 no Chance in running #2 with out Up-Grade's to your Cylinder Head's and a Bump in C/R . Again this is if that 400 is a Stock Long block ?
