If you would of mentioned Edelbrock 750 from post #1 , four things would of happened

1) 25% of us would of said , don't even waste your time on fuel percolating , you have bigger issues , like finding the nearest garbage can

2) 25% of us would of said , don't even waste your time on fuel percolating , you have to change the jetting , metering rods , springs , check your float levels , drill this that and everything will be ok . Then back to the original topic

3) 25% of us would of said , put a Holley on it

4) 25% of us would of said , what's been discussed so far

I like the Edelbrock 600 / 800 Performer Carbs
Also the Thunder Series AVS Carbs

And the Factory Carter AVS Carbs 750 cfm found on the 440 HP Motors
