My '66 GT350 has an original Shelby-American Paxton installation with the Autolite 4100 jetted per their factory recommendations: drilling the secondary jets to .086 diameter (#44). Mains stay the same. I've also heard of guys 'going one size larger' all the way around..... (BTW, let me know if you get this, Cevon - my test for the new list/system.)

dyno takes the guess work out of what you have vs what you need. it will be only a rare coincidence if someone else's jet sizes work for you vs what the dyno will suggest- assuming they monitor your exhaust for air/ fuel ratio. I had a 60s era Paxton VR-4 spec'd supercharger on a 351 windsor in one of my toys. whadda kick. however, you dare not run them too lean or you fry your engine, and the bottom end better be set up for a blower ( carb too ) or good bye engine. keep it rich, and boost down, and the engine will survive. craig conley at paradise wheels in calif can answer any tech questions you might have-- but use the dyno for the jet sizes to get you the ideal air/fuel ratio. enjoy it- nothing like the sound of that blower when it spools up and pins you to the back of the seat- or just whistles at the stoplight letting others beware. bill, motown -----Original Message----- From: shelbymustang-bounces (AT) thecarsource (DOT) com [mailto:shelbymustang-bounces (AT) thecarsource (DOT) com]On Behalf Of fordfever97140 (AT) yahoo (DOT) com Sent: Monday, June 12, 2006 9:31 PM To: cmclean (AT) rbhnrc (DOT) usda.gov; shelbymustang (AT) thecarsource (DOT) com Subject: Re: [Shelbymustang] Paxton Jetting question.
