Yes, the 1275cc engine is essentially the biggest A-series engine (there is
also a detuned 1300cc variant, I think). The 1275 is quite redesigned from
the previous A-series engines. It is still by default a 2-intake, 3-exhaust
head (it's a short engine), but there was a BL Special Tuning 8-port, crossflow,
Aluminum head (drool). There's a picture of one with dual Webers, all running
at full bore on a dyno in David Vizards book on tuning the A-series engine.
