All right guys,

We got a .410 lift rule for cams. Everything I've read means that it runs out about 4,500-5,000 rpm. Anyway, what's a good one to get.

I'm actually running a 283 .030 over and this will be my first year out. Right now, it's just got a stock cam and an old 2bbl and I'm putting a 4bbl carb and intake on it.

I'm in the desert right now and I'm trying to get all the parts together to get the engine put back in and running soon as I get back in Feb.

Thanks for the help

Howards Cams make a number of cams for lift rule engines. Check 'em out at www.howardscams.com or you can call 'em at 920-233-5228. They have several in their catalog, with one showing an RPM range of 3500 to 6800, so you can get one that won't run out at 4500-5000 RPM!! They will grind anything that you want. If you call them, the techs are very helpful. Tell them what your setup is, and they will make a recommendation on what cam to run.

I got one from them that is a .450" lift rule cam for $99.95 with a new set of lifters. They give the RPM range as 2200 to 6500, can't wait to try it!!

I think the best way to get around a cam lift rule is to have one custom ground. We got one custom ground from cam craft cams. It worked exactly like they said it would.

I believe Elgin also makes lift rule cams. You are going to want to know the compression of your engine, RPM's desired, what heads you have, and what exhaust you are running when you call a cam place - seems like they all have good tech support. Just be realistic when talking to them - if your engine is going to go ka-boom at 6200 rpms then get something that makes power a little lower. Good luck!
