In the UK they came out of the factory with HS2 SU Carbs with AN needles. Removing the springs and filling the dashpots with brake fluid gave a faster throttle response.
Later we started fitting Nicky Carbs, they had a glass pannel in the float chamber. Webber Carbs were very prone to freezing so on alchohol I think they would be a none starter. I have never seen throttle body injection on any A Series engine but I think you can get a retro fit multi-point.
The strongest A Series Engine was the 1071 Cooper engine, it had solid little ends and offset big ends, but before I get told off for going off topic I will shut up and again wish good luck with the project.

I found that to get the advance curve correct with the higher compression ratio I had to fit a Mk2 Cooper distributor body (the one without the vacuum advance) to get the right spring rates and bob-weights.
Dyno'ed at 75 BHP at the flywheel but now we're getting even further OT!!
