Ok so I need a cam for my Hotrod. Its a 49 chev pickup with a 454/th400 and 3.08 gears. I have an Edlebrock 750 carb on a Performer RPM 2 intake. The heads have had bigger exhaust valves put in them along with opening up the valve pockets. Its running around 9:1 comp. Well now I need/want to get a cam for it but I have no Idea what to look for. I called comp cams and they suggested this Lift int/exh .547/.547 Duration @50 int/exh 232/237 LSA 110 I found these 2 that are in my price range and SEEM simular Operating Range:2200-6200 RPM Duration Advertised:286° Intake / 286° Exhaust Duration @ .050'' Lift:236° Intake / 236° Exhaust Valve Lift w/1.7 Rockers:.556'' Intake / .556'' Exhaust Lobe Separation Angle:110° and Basic Operating RPM Range: 1,800-6,000 RPM Duration at 050 inch Lift: 230 int./236 exh.
