I have a 250 kew motor , & wish to put triple carbs on it. I have seen many with triple SU's , or triple stromberg/carters , but am thinking triple Webers. As these are cheap & currently made . Any opinions from people on this also are the downdraft Strombergs any good ? Or really too crude compared to Webers?

Thanks, cheap is a relative word, I can buy a new weber for $289.00 $aus. I can buy second hand ones for a lot less, but if I did they would require work to undo years of people fiddling & possibly a rebuild . the bargain used ,becomes not such a bargain. New Stromberg downdrafts are advertised here in Australia as $600 each! Reconditioned often for the price of the webers. & I believe Webers would be better than Strombergs. Used Strombergs are common but all at best would need stripping to match jets etc, & all ,by now ,for decent performance would need the butterfly shafts rebushed adding more cost.

Not sure about all Weber DCOE's but mine (made in Italy) were ball bearing shafts & were sealed, great for blow through apps.
I would go with the Webers if you can.
I would get a book on Webers & do some research for the ones that would work best for you.
The more transitioning holes, (holes in the bores close to the throttle valves) the more the better, smoother, better drivability.
IIRC, my 48 MM carbs were made for a spec class of racing & only had 3 transitioning holes in the bores, had more of a on throttle off throttle feel, not so smooth, but I got used to it.

Thanks, everyone seems to think webers when tuned have the smoothest power delivery. Though some people seem to think SU's are easier to work with. I have come to conclusion people like what they know. I am still looking as there is plenty of carbs to choose from . & at times think simple carbs Stromberg or carter for simple people like me. As my Mopar is a hobby not a daily driver I think I like the idea of getting the best out of a carb. Any suggestions on intake runner length? I am trying to get power at 2500-3500 revs, this is where I mostly drive.

There is an adjustable jet available for the single-choke Stromberg used on the 202 motors in HQ Holdens. This makes them a nicely adjustable and very simple - as well as cheap - carby.
If you were talking about Weber DCOEs, how did you plan to use them? Use one choke of each?

The Webers I wish to use are single throat. downdraft carbs. Just a more refined Stromberg.

Sounds like by the time you buy the webbers you're most of the way towards the cost to buy a new EFI system...

This has crossed my mind, Thing is I can understand carb's ,But would not know where to start with EFI. Cost is also relevant, this is a looooong project so any cost will be regained with years of tinkering pleasure. There is no logic to doing up this engine, it would be more practical to go down to my wrecker & buy a current OHC inline, I just want to do it.
