Only reason I would go with a Mikuni before a weber is because of the OMP lines built in. I am lazy and don't want to start pre-mixing. They also work well on a stock port engine.
The weber will make more power though. . .

Did you see a desent HP increase with just the carb and not the exaust?
(looks like the stock header on there)
To everone:
Wouldn't it make better power if you curved out that intake manifold a bit more. Those sharp angled bends have to be cutting your intake velocity down a good bit.

Really though the factory throttle opener canister and solenoid could be adapted to any carb, if you really wanted.
Or you could shut the A/C off when you're sitting there idling.

I found that stripping the interior out makes it approximately 400 degrees hotter in the car in the summer, basically a car becomes a toaster oven. I can't handle that kind of heat anymore. If i stripped the interior out of one of my cars, I'd adapt some A/C for sure. (I say "adapt" because the OEM type stuff has got to be horrendously expensive by now)
Steve, glad to see you got the carb mounted up!

they are different. unlike the weber and dels, mikuni's main jets are screw-in type instead of push-in.

The picture was taken right before I put the Racing Beat on. Night and day difference from stock.
