i bought a edelbrock carb on my first engine build since the factory carb died. it lasted a couple of hours till i had to pull the top off to realize it had to leaking floats from the factory. then swapped 8 times trying to get a good one thru oreillys till i got my money back, then bought a 680 cfm hotrod series quickfuel carb and never had any issues since. only thing good about edelbrock is there intakes. they should quit making carbs. quickfuel the only company with actual good out of the box carbs.
