Changing Cams
Yea, it might be a touch lean at idle. Having stock exhaust manifolds doesn't help either.
The 850 rpm idle is in neutral, as it barely will idle in gear.
The compression was measured with 0 deck piston with a 19cc dish, 57 cc heads and a 4.140 bore head gasket at .038 compressed thickness. The only thing that was not measured is the cc around the piston to the first ring. The stroke is 3.58 and the bore is 4.070 with a stock rod.
I thought about going to Rhoads lifters too, but just seemed like a band aid to me.
