Holley, alot of R and D by Racing Beat, very good setup (driveability, and power both very good) every part under the sun is availiable for them and will be for a very long time.



Weber, decreased driveability over stock, VERY easy to tune, parts are widely availiable



Dellorto, because!! Parts are becoming hard to find, but it's still cooler than the Weber, IMO!

I have heard that the Holleys are not as good as the sidedrafts in a road racing situation, because of the way the floatbowl is set up. You know anything about this Ryan? (or anyone else)

holley: works well, it will be available forever



weber 45dcoe: i dont know a lot about this, webers are more tunable than a holley....



dellorto: its too small for a ported 13b, and its really hard to find



weber 48ida: its kinda like the holley kit without a choke, they are making 48ida's again

Yes the Holley is not ideal for road racing, ralling, or any where the car will see high speed long duration cornring. The Holleys will flood under these conditions, but since this is a Holley we are talking about, and everything under the sun IS produced for them, you can get competion float bowls, and voila, problem fixed.



If you are setting up the car for road racing go for an IDA or an IDF downdraft, (reproduction IDA are $930 for the carb. Gene Berg Enterprises) The side draft would be the compromise between the Holley and the IDA. Side draft is more ideal for autocross. The long intake manifold associated with side draft allows for more midrange power than with the IDA or the Holley.

So far I have found more stuff for the holley. hmmmmmmm I need numbers.

go for weber!

Go with Holley.I like the fact that parts are available anywhere for the holley's and you don't sacrifice much driveability over stock like the weber does.My dellorto works awesome but try finding a Dellorto setup.They are hard to come by.If you were doing a 13b another choice for a carb would be a Mikuni 44 i hear they are really good too.

This one looks good. I was wondering if I can put a 650 Double pumper on a stock 12a. Would it run right or do I need to do more mods.
