EFI is the way to go with full control of the ignition, as most l28 with your combo will have a dip in power around 4000rpm and will run very rich in this spot and is very hard to tune around with carbs.
If you need help to go efi i can help with the parts and the tune, the only problem with efi is the initial cost to set up.
I like to use Haltech and you will need a full sequential computer to get it to run the way you need it to this will be around $2200.
Distributor cost with home and trigger around $600.
6 X LS1 coils around $50 each.
EFI hardware individual tapered throttle bodies size 48/45/43 cost ? best to call EFI hardware and check price.
You can use your Weber manifold to save some money.
6 X Injectors all up roughly $500.
Fuel pump high and low pressure and surge tank will be around $600.
Fuel line and clamps roughly $50
Installation of parts cost will vary depending on if you can do some yourself or have it all done for you.
Tuning will mean the car will be on the dyno most of a day so you will be charged per hr at around $100 an hr.
Any questions just give me a call.

Junk the Webers and install a set of Mikuni's !
I know of a set of Triple 44's for sale that were running on my old 240z Sc race car (turning 145 rwkw from a little L24 !)
The Mikinu's are complete with linkages, manifold and 50 mm ram tubes...................and ready to bolt on
Once dyno tuned properly you won't need to touch them again
I think the asking price is around $2500
PM me if you are interested

So go for the fuel injection. You won't regret it. Who knows you might even save some money after 10 more years of running it like that. You know the you will still have the car then.
Go for it!

Dont get me wrong , I love my carbies but if you are having probs and there is no one to tune them correct its not worth the hassle.

I had my ol 2nd hand 40mm webbers setup properly from day 1 with a conservative recipe to match my stockish engine, and theve been running perfectly.
If your running a stock to mild L28 I wouldnt recommend 45mm dcoe. It sounds like your your trying to de-tune the carbs by trying to use smaller venturis...
You can only choke-back a carb so much.
what recipe is currently in them ? how worked is your engine ?
also have you considered a type 5 hotter plug ?
haha Peter you posted 13 secs before me, Im sure youll sort them
