302 performance question
i have a 302, with a holly carb, electric fuel pump. for some reason id dosent excelerate well anymore, the motor was rebuilt 3 months ago, when it was rebuilt we put an orignal autolite carb on it "brand new" and for some reason the carb messed all up <ie> loose screws in the carb floats stuck all the way up, leaking gas, so we replaced it with the holly. anyway. when i excelerate i hear a gurgling type sound and it sounds like its comming from the motor, i was thinking maybe to much gas and i should adjust the floats. just wanted to get some imput on this before try this.. any ideas?

Re: 302 performance question
dose it do anything beside gurgle? if it was to sputter or die at all you might try adjusting your accellerator pump, i know on my 67 its been running like crap since that went out of adjustment

Re: 302 performance question
Too much Carb...
Tone it down. I'd suggest something that surprised me... a Holley 600 with vacuum secondaries. Pick up a spring kit and a trick kit... and enjoy a day of holeshots and burnouts trying to get the best set up. I found that a more aggressive carb cam, combined with a lighter spring really worked well with a moderately enhanced 302. |
