Cam for 400
I'm doing a little work to my 400 small block. I'm going to put an edelbrock performer intake on it. I'm debating on what cam to use. I'm thinking one of these two:
Comp Cam
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.
In our neighborhood, 2 blocks down the hill was a gas station that (to me) all the cool car guys hung out there. 32 coupes, 33 & 34 Fords as well, a sweet 56 Ford Beach wagon that was setup gasser...
How did you get hooked on cars?
