what kind of idle should I expect with this cam that i just installed
specs:
advertised duration:292 intake/292 exhaust
Duration@ .050 in.cam lift:230intake/ 230 exhaust
Gross valve lift: .480 in intake/ .480in exhaust
Lobe seperation: 109 degrees
are any of you guys running this cam?
its a Lunati Bracket master II

 

In what engine?

I'm going to assume its a 400, and if so it will probably have a little lope to it, but not alot.

 

yeah it is a 400

 

I have the comp 292 magnum, 246@.050, .501 lift and its lopey as hell @ 1300 rpm idle

 

Alot of people have been running that cam from dozens of mfrs for the last 30 or 35 years. There are far better cams nowadays. That cam was designed back when there were no decent valve springs available and oil was much inferior. Something with steeper ramps (less "advertised" duration and more .050" duration) and a 10° or so bigger exhaust lobe will run a whole lot better. Notice the other post whose 292 advertised cam has 16° more .050" duration; i.e. it will make far more power (more .050"), and idle the same as yours (same advertised).

It is definitely too much cam for an automatic trans with a stock converter and a 350. It might be tolerable with a 400 and an auto but will still be difficult. With a stick or a very loose TC it will probably be OK.
