hi,
the problem is it is a older rherer morrison motor that is fresh and leaks down at 2% or less and advertized hp is 825 and i had it dyno'ed and it was down to 756 with a much flatter curve. just a working guy here and funds to play on the dyno do not exist. a friend of mine has a quickfuel 1050 on a 555 and the sheet with his carb says 93 jets, nozzles 35, idle air bleeds .053, high speed air bleeds .037, intermediate bleeds .095. now mine: 94 jets, 42 nozzles, idle air bleeds 41, high speed bleeds 31, intermediate bleeds 100, both are hp models. idle has never been what i would call correct but not bad, no stumble when you stomp on it. on the holley site it says not to adjust air bleeds more than 6 sizes in any direction from original, which i dont know! and my high speed bleeds are at that from the quickfuel numbers. mainly looking for the lost pony's and this looks like a likely place. if it was down 25 horse probably wouldn't be looking but 75 i've got to take a look!
