hi paul
no progress as the project is on the back burner whilst we sort out the twin 40s
my favoured option is to fit twin 150 strombergs to a alloy headed 1725 engine,this is the standard fastback rapier /humber sceptre fitting and works extremely well in my fastback rapier
having remved the panel the air filter sits on there is enough room to fit them
think this is commerjules solution as well
the 28/36dcd carb works extremely well on the 1725 engine as i have this setup on my 63 vogue and it will top the ton

the engine lid height and air feed is the problem and is something we are going to investigate.this carb was fitted to rootes cars of the 60s that had twin choke solex setups which were exteremely unreliablse
ive just bought a pair of twin 175 strombergs as fitted to vauxhalls to see if theses would fit so giving another possible solution
must admit the alpine set up looks very good tho
