Other than adding a few BHP (Bar Horse Power, as in bragging right at the bar) I'd stick with the SUs.

If you're not confident in tuning the twins (I'm assuming HS2s) consider an HS4 or an HIF44 depending on the state of tune of the engine.

Agree with Maisal. I suggest you read Vizard’s exhaustive dissertation “Tuning The A-Series Engine.” I think you’ll decide to stick with the SUs.

To quote Vizard there are no gains with a Weber on a road car, the only small gains are when you are flat out racing.
Also if your bulkhead does not have a box you need a swan neck manifold which decreases the efficiency.
If you don't like the twins a HIF 44 would be a better bet imo.

If in doubt, flat out. Colin Mc Rae MBE 1968-2007.

make a car lighter and it's faster everywhere. Colin Chapman.

Austin MINI 1972. I have a dual SU set up on my 1275. Think about going to a weber. Any ideas/feedback would be appreciated
