Now that the milder 2056 is in the car, I could use some advice on carb tune.
compression is at 8.8:1, valves are 44/38, cam is Webcam 86a. Weber IDF 40's have 37mm venturis, 135 mains airjets 200 F11 emulsion tube I am told by the builder that I should step down to 34 venturis, but, have no idea where else to start. Car will go to a good tuner soon enough, just want o have a good starting point. |

I have a very similar engine combo in my '73 currently aside from the heads having stock valve sizes. At sea level I am running 40 IDFs with 32mm vents, 125 mains, F11 tubes, 50 idles, and 200 air correctors. Power band starts waking up at about 2500 and pulls strong through to 5700 or so. My engine also has AA forged rods, Web single coil valve springs, solid rocker spacers, MSD ignition, 2.0 SSi's, and a Triad muffler. The whole combo seems to work pretty well for a carbed car. Runs relatively cool, has good idle performance, and great response in the power band.
