I don't necessarily agree about not passing the smog test with a Weber. I
rebuilt my 1500 using a standard cam (the hi-lift cam made the engine too
"lumpy" at idle), dual valve springs, high compression pistons, 32/36 DGV
Weber, Mallory Unilite distributor, headers, Monza exhaust, and free flow
catalytic converter. I added a crankcase breather using the mechanical fuel
pump opening and connected it through a hose to a PCV valve that is threaded
into the Canon manifold. I get about 10.4:1 compression (172 psig) since
the head was milled. I passed the Georgia test with no problem. The test
standard was 6% CO, the engine spec was 1.5% +/- 1%, and the engine put out
2.5% at idle and 1.9% at 2500 rpm. I don't know what the horsepower is, but
I've increased it a noticable amount while keeping a smooth idle.
You probably won't pass with a DCOE (racing) Weber, but the dual downdraft
DGV gives good performance and is much easier to keep tuned than the Zenith
Stromberg.
