Is this a good Hydro Cam? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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
