Cams

[squint]

I am wondering if there is someone here who could explain to me a little about cams.. what the numbers mean exactly.. and how it translates into torque / HP?..

i just dropped a new 350ci engine into my truck and installed flat top pistons and a 350HP Cam.. The engine guys told me it would put me right in the 350 HP range.. I might have 350HP.. It does have lots of power.. but does not seem to have much bottom end torque.. I am thinking maybe i chose a bad cam.. ?.. Perhaps i should swap it out for something else..

Thanks in advance.
