Need some jetting advice
Need some advice on jetting for my car. It's a 2.7 with cis cams running about 9.5-1 compression with 40mm webbers and stock ignition. Normal driving will be at sea level with the occasional 4000 ft run to get over the grapevine.
Whatya guys recommend??? |

Hi:
60 idles ARE indeed way too fat,...  Use 32-34mm venturies with 55 idles, 140-150 mains, F26 emulsion tubes and 180 air correctors. Make sure your fuel pressure is 3.5 psi and your float levels are PERFECT. You also need a very good fuel filter setup since Weber's are quite sensitive to dirt & water.
