There was a post earlier that asked about the diff. between Mikunies and Webber carbs (side draft) or something along that line. I have heard that Webber carbs have more tuning capablities like swapable venturies, but you lose fuel economy greatly. I have not heard much about Minkunies except that they dont worsen your mpg as much as webbers, but how tunable are they? I am planning on getting a triple carb setup to replace my DGVs that piss me off every time i look at them. Goofy pieces of crap! AHHHHHHHH!

BTW.... I have a 72' 240 and plan on getting a Motorsport 6 into 1 header, a cam kit and already have a CranCams XR3000 ignition. It will also be a daily driver.

Any info and advice would be greatly appreciated.

sorry 3 twos just isn't a good option for a daily driver.

Ignorance surfaces...

Anybody spouting that triples aren't a good alternative for daily-drivers is grossly misinformed. Skip that advice.

Mikuinis have all the tuning possibilities that Webers do, with the exception of the emulsion tubes. For Mikuinis there are only two choices, and they are dependent on whow old the carbs you have are..
The Mikuini is set up as an OEM carburettor. In japan, they came STOCK from the FACTORY on so many cars I can't list them all here. they offer true daily-driven torque and progression with long wear.
The way the carb is designed, it's set up to work over a range of applications. Kinda like the "Holley of Japan". They have the interchangable venturis, jets, and a big accel pump, which lets you drive the car lean on the idle circuit for MPG on a 240 approaching 25mpg, while allowing the dyno figures for the car to be in the 135-145hp range. This is for a BONE STOCK 240! No header, no cam, no timing adjustments. There was jetting time spent, but that's about it. The car has 115-120 HP before the switch with some strong-running SU's.
Look for some real-world dyno runs of a stock 240 (not ITS Racing Prepped, STOCK off the street) and you will see that is an improvement of exponential porportions!
The car was MUCH stronger in the midrange, and would pull all the way to 7000. This car would run almost 110mph in third gear! After we swapped to a 370 rearend, and lightened the flywheel, the car was just a blast to drive. It would average 25mpg driving in SoCal mixed, with 17 in the city. The best I ever got was 28MPG on a trip to phoenix at a very steady 60mph with the original 3.36 gears.

Oh yeah, an it was driven like that for 5 years, daily, before being sold out in Phoenix. As far as I know, the owner STILL has not played with synching the carbs, or changing anything on the setup because it works so well. Then again, real world can't compare to illusory fantasies, can it?

i totally agree

i have the dellortos on my 240 though it is stepped up a bit. and im telling you i dont know what yurmohill is talking about. i had the dreaded dual downdraft webers and they ate my gas mileage. i actually with my triple dellortos, have gotten 4 miles to the gallon better mileage, and top end performance has greatly improved. before with the dual webers my pull wouldnt go after 6000 rpms and was not significant but still there from 5000. now with this setup im pulling hard still to 6500 with no probs. i was driving it daily also. i totally agree with tony it is the way to go. to those that dont know the 240 in japan came with triple mikuni's stock!! hmmm they wont work on a stock engine, dont think so
