what is the best carb setup?
if your looking for good gas mileage your pretty much out of luck... But I would recommend going with a weber 48dcoe, or the weber 48ida, if you want your car as a daily driver the dcoe or for a weekend racer the ida.
The Mikuni is also supposed to be a very streetable setup as well. Remember though for any of the setups you choose you will need to have full exhaust done, a upgraded fuel pump and a fuel pressure regulator.
Right now I have a weber 45dcoe but if I could do it all again I would hold out for a 48 ida because it could handle a huge streetport or another demanding engine... And at the same time it would have massive amounts of high rpm hp which my dcoe seems to lack in a little bit (performance seems to come from the 2500-6000 rpm range)

I actually get pretty good mileage with my 48 IDA on a big streetport when not ******* it every second. (2.5-3 days between refills!) Running 65f10 idles it will cruise along perfectly and really quiet at 2000rpm in 4th gear....between 35 and 40 mph. Then the instant gratification when you get on it. I really would'nt even bother with a holley...sidedrafts are ok, but buy 1 carb and buy a 48 IDA, you'll never go back.

I'd have to say Holley's all the way! I had the Weber set up (actually had 2 diffrent 48's) and then switched to Holley after seeing all the racers (drag) that ran carbs, using them. Not one drag car that I have seen ran a Weber, not to say that there not good but I think it has to do with ease of part availibility and adjusting. My car is street ported with a holley 600 cfm and I couldnt ask for more!

edelbrook makes a good carb i had one on a old 2nd gen that i converted to a carb. It picks up better than the holley. Im pretty sure it is beacuse it is a spread bore carb but a holley will flow more cfms at a higher rpm range but i think it was to much. THe holley i had started to lean out at around 5500 i didnt have ne problems with the edelbrook though.

Sterlings are good but you gotta wait forever to get one! Besides I think you are limited to the a stock motor or small street port with a sterling carb.. Not sure though. GO HOLLEY!

sure v8 drag racers use holley's but what do all the big time rotary drag racers use? IDA weber... PERIOD. For damn good reason too.
If you want better milage get a holley, if you want better power get a weber

I paid 600 for 1 and an intake manifold.
