NOoooooooo dont go there, the firing order is all wrong, induction pulses, dead spots, complex linkages blah blah blah
Buy some triples and save your self the hassle, better still buy some throttle bodies and go faster than all the rest of the flock.
If though your still interested check out http://zhome.com/ZCMnL/tech/TripleSUs.htm

Qunvat,
Nice 2+2, by the way. But if you are wanting more power, start by getting rid of those pancake filters on your SU's. Far too thin for filtering and there is no venturi on the carb. You have some decent spark plug leads, so what about getting your carbs breathing properly. Anybody else agree? Just a thought....

You need a minimum of 25mm clearance between carb intake and outer plate of the air filter for anywhere near decent airflow into the carb. 30mm minimum preferred, even more for elevated BHP. If you run ram pipes, then the measurement is taken from the outer lip of the ram pipe bell.
e.g. in a 63mm K & N filter you could run a 30mm ram pipe successfully, in an 83mm K & N you could run a 50mm ram pipe.
On twin 1.75" SU type carbs, a pair of 63mm deep K & N will be good for 190-200bhp and a pair of 83mm deep will cover your requirements up to 265-275bhp!
The Brown & Geeson (for our older readers) wire gauze thin units seen in the picture are almost certainly reducing the horsepower potential of even a stock engine...
