See sig for mods, obviously i shouldn't have that low of an idle with that cam. I checked for vacuum leaks. One of my fellow techs mentioned something about a valve hanging open. The problem is only at idle and low RPM. Needless to say this is messing with the FP and MAP sensor, and its really bothering me.

Also, the car used to stall in drive when I came to a stop, but i "fixed" that by bumping up the idle screw temporarily.

 

Hmm...I never had a vacuum guage when I had a stock cam, but to me that sounds pretty high if thats at like a 700rpm idle. My motor has about 9-10 inches at 1,100 rpms with the 246 duration @ .050 comp cams.

 

sounds perfect to me. I get 14in with my 218/224 .496/.503 112 cam

 

I get about 11 pounds with my 305 with this cam:

Competition Cams XE-262H-10
Part Number 12-238-2
Intake Exhaust
Lift .462 .469
Duration 262 intake 270 Exhaust


at about 750 rpm.

So it sounds to me like you're doing fine.

 

Doesnt sound right. I had exactly that cam in my 305 and it had 16psi at idle. Try adjusting your timing.
