Harold,

it depends how accurate you want to be. According to Peter Browning's 
"The Works Big Healeys", talking about the rally cars he says:

" The 1960 cars ran with triple 2-in (51mm) SU carburetters on 
individual inlet manifolds...[producing].. 180bhp at 5200 rpm.

The use of triple 45 DCOE Weber carburetters in 1962 improved power 
output to around 200bhp at 5750rpm with a 10:1 compression ratio and a 
high-lift cam"

I would get hold of a copy of Browning's book and go to the back and 
think about how far you want to go!!

Hope that this helps.

Peter

I purchased my BJ7 from its original owner who had bought it new in 1963.
In 1965 he decided to take it SCCA racing and when I got the car it had
triple HD8s and a BJ8 cam. He told me he had bought the carb set-up from
"Healey of Canada". I did some research on the carb and manifolds and found
the numbers matched to ones allowed for SCCA racing and were in some Healey
literature parts lists. I found the carbs were great at wide-open throttle
(like you'd use on track) but lacking in acceleration at lower speeds. If I
were going to fit triple SUs on a road car, I'd probably stick with HD6s
rather than HD8s.
