Just wondering what size primary and secondary jets, along with rods and springs people are using on a mild 350?
I'm currrently running 0.098 primaries with standard secondaries, with 073-052 rods and pink springs. (it's number 24 on the tuning graph chart)
It still seems to be a bit rich though, just interested in what others are using?
The motor is a 60 thou over, Edelbrock ED5073 heads, crane energiser 266 cam, Crane roller rockers, Edelbrock EPS inlet manifold, NGK BPR7ES plugs and timing set to 12 degrees .
It's running ok, but I'd like it to be running better...........

Edelbrock tunes their manual choke carbs for performance. That could causing the being rich.
Every engine is different and what works on some thing with similar or same specs may not improve or work on yours.
Air temperature and sea level are factors to consider too, as many others.

I think you should tune it like described in the Edelbrock manual, worked good for me.
I had a vacuum gauge and an exhaust gas meter borrowed from a friend of mine, that helped a lot for tuning.

My specs on my 8 years old Goodwrench 350 crate with stock cam and a edelbrock performer: 1901 AVS2 500cfm,
Main jet primary: .095" Main jet secondary:.095" Metering rod:.070" x .052" Step up spring : pink (7") at 1000ft elevation

Works great from idle to 4500rpm.
