Hi guys,
I have something that is bugging me for some time now.
When I rebuilt my 292 back in 2010 I installed a Isky E-4 cam. The car runs great, and even tough at the time I installed the cam out of the box, without deepening the oil groove, the engine has great oil flow to both heads.
The thing that buggs me is the idle. The car never had the same idle it had when all stock. I was told the E-4 is not enough to alter the idle (not that I wouldn't install it because of that) but my engine doesn't idles as smooth as before. Along with the cam, the engine also has double valve springs, and 1,54 rockers. When all stock she had the lower ratio rockers.
Valve lash is correct, the carburetor is good (Autolite 4100), the car has no ignition problems, and drives super well, with no hesitations, flat spots, and has lot's of power. The problem is just the idle that is more vibrant than a stock engine.
My fear is having messed something out when rebuilding the engine.
For you guys with more experience on comparing cams, is the E-4 enough to change the idle?
Other than that, I've put more than 20 K miles on the 292, and it uses no oil, has more than 30 PSI of oil pressure idling at 750 RPM hot, and has a little more than 60 PSI on highway.
What do you think??
