Love these little cars!  Group: Members Posts: 2,443 Joined: 11-June 05 From: Port Townsend, WA Member No.: 4,253 Region Association: None  |
I've been playing around with metering rods, springs, and jets for my Edelbrock 600 on my conversion SBC teener, using primarily a vacuum gauge and AEM wideband. I'm currently getting these type of readings
Idle-around 14.5 Cruise Mode--light throttle: 13.7 Power Mode--Heavy Acceleration: 12.3 I'm curious what kind of ratios you carb guys run? The car runs great, but I just wondering if I need to lean the power mode out. The motor likes these numbers and the plugs look good. Also curious, anyone with FI have some numbers available from their wideband? Thanks, Mark Attached image(s)

You can lean it out a little bit for your primary jets and richen your secondary jets to get cruise closer to 14.5.
I think my idle is dialed in around 17. Anywhere in the 12's is fine for a carb'd SBC at WOT. |
