Whats my best carb with little work and good performance?

Holley still makes one darn good carb, its just seems to need fussing with every so often--it can last all season...it does seem more fussy on just the right jets.

Carters/Eddies are easier to set a tad rich at part throttle to work great in cooler temps yet still have the best A/F ratio at wot. The metering rod's swap sure beats changing jets on a holley--don't miss that part one bit.

Changing both secondary jets on my duals is a pain and takes longer, lucky Edelbrock was pretty close on the .077 jets they recommend for Chevy's. I tried a few sizes up and down, got .080 in it now, seems best

Funny thing is stock the 500 carb came with .095 jets or close to that. Was way down on power--I just had to try it, ha ha

If I had to pick just ONE carb for best power, holley/demons would be it. Hard to beat the power of a 750, 950 or even the 850 carbs. Yep, holley's 950 flow less cfm than the 850's...look at the specs
