If you were to buy a "Factory" unit from holley, you probably be good. It's the Fly by night operators on Ebay that you'd want to be careful with. I've heard good things about the Summit carbs as well, IO would not be afraid to try one of them.

I have not ruled out a Holley 600, just have no experience with them. But I would still consider it with the two previous options. I see some factory rebuilt holleys on ebay (refurbished returns) but I dont know where to look as far as model numbers or carbs that would fit my manifold. I swapped my stock manifold out with an ECZ9425B to work with a new carb and get away from the "dizzy" distributer. dI just want a new or refurbished carberator (electric choke) that will run good and give me good performance. There are too many model numbers on Holleys, I dont even know where to start looking.

I run an Edelbrock 1405 on my F code. Seems to work pretty well. Very consistent at the strip, but not legal for pure stock. I'd disagree with Charlie about the tuning, with the instruction manual they provide it's a piece of cake. But then so are the Holleys. Be careful buying a used Holley, many of the older ones had Quality problems.

I have no experience with the summit carb but based on what others have experienced, I would not hesitate to try it.
I find the Edelbrocks to be a pita to tune and they just are not generally as tunable. Pita doesn't mean hard.  It's just that metering rods only get you so far and when it gets to the point that you need to swap jets, there is a lot of screws and clips and little things that get lost easily to be removed and it is made less pleasant when the tuning is being done on a hot engine - I'd rather have a Holley style carb when it comes to tuning - much faster jet changes, fewer parts to loose and less time handling hot parts. I also had an issue with my 600 Edelbrock where the secondary air valve did not work correctly with my combo. That can also be worked around by grinding on a counter weight but on a Holley you just swap a spring and you're good.  Most of the time there does not seem to be a problem with that, however. Of course Edelbrock now have the AVS with the adjustable secondary air valve but it costs more.

Of the two options I'd go with Summit simply because I haven't used one yet.

Hey Charlie, Im going to pull the plug and order the Summit Carb Part # SUM-M08600VS or the Edelbrock 500 performer for my 272 (Daily driver stock engine). Im having a hard time making up my mind which way to go. Anyone else who can offer some guidance, please chime in.

Thanks Charlie. Looks  like same carb, one new and one remanufactured which is probably good as new.

Billy, I checked out Summit, but I dont see anything listed under Ford style carb. Can you paint me a picture?

1955 ford V8s were 272 and 292s with the vast majority being 272s. The 292s in 55 were the interceptors bought thru law inforcement or if you were friends with a dealership owner who would fudge the cause.

And Mercurys and in Canada Monarchs as well.
