Im selling my Speed Demon 650 vacuum secondary, tuned for a mild 350, jets were changed to 66 primary and 76 secondary, power valve 10.5 and restrictors enlarged, idle air bleeds modified, comes with vacuum secondary spring kit, fuel log kit, and original box. Works great, runs 14-15:1 cruising 12.5: with power valve activated and 13:1 WOT just going with a more racing dedicated style carb.
