It's a mild performance cam (assuming you have a 350) that will work well with stock intake and exhaust manifolds, and prox 8.5:1 compression. Peak torque is probably around 3000 PRM, with peak hp at 4000. You will have a smooth idle and lots of low end torque. For comparison, here are the cam specs for the very mild 350 "Goodwrench" crate engine:
Camshaft lift: 0.390” Int/ 0.410” Exh Duration @ 0.050”: 195° Int/ 202° Exh Lobe center: 115 degrees The more agressive exhaust lobe compensates for "lazy" stock exhaust ports. For some really good cam info, that actually takes engine size into consideration, check out: http://www.crower.com/misc/m_cat.shtml Then go to Page 24. ------------------ MikeB 69 C-10 Fleetside, mild 383, Dart Iron Eagle 180cc heads, Crane Energizer 266 cam and 1.6 roller rockers, Edelbrock Performer manifold and 600cfm carb, HEI w/ MSD components, 1986 front spindles/disc brakes, Vintage Air in-dash, lowered 2"/3".

I have a simillar cam in my truck's 350, 204 intake/214 exhaust duration @.050 lift, and the valve lift is around .444/.443 if i remember correctly. I am happy with it, it has alot of power (about 300 horses in my engine) and great low end tourqe. From 2000-3000 rpm, in the highway cruise RPM's, it has plenty of power for the pulling hills.
