New to hobbies and was just curious as to what cam to look for. I have worked on mods for years and now am going to try to build a motor for a hobby stock.

What is everyone running so that i have an idea where to go duration/lift etc.

Probably run up to 6500 rpm but not sure.
Are you guys using solid or hydraulic cams?

use a solid lifter camshaft. you can get away with a bigger cam and not kill the bottom end like a big hydraulic does. try something in the 240 to 250 degrees of duration @ .050 range with a lobe center of around 108 degrees. that seems to work best for limited engines. anything much bigger is going to put your rpm range above the range of your heads and intake. the key here is to have all of your components matched for maximum efficiency.

on another note, if you're running a chevrolet and a 400 is legal, get one. the only substitute for cubic inches is rpms and big rpms=big dollars.

Well the cam you use is dependent on the rest of the engine. Please give more details on your engine.

speedpro/elgin makes a .510/.533 lift cam that seems to make some real nice power. You might look into that one, and it is only like $60 at Midwest Motorsports.

i used a 535 lift when i was running factory stock and when i changed to super i bolted on a set of darts and still run the same motor but recently jumped to a 585 lift (both solid) 535 is a better low end cam if you want power at higher rpms the 585 will do nicely
