<div dir="ltr"><div dir="ltr">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.</div><div dir="ltr"><br></div><div>Rick Neville aka "HealeyRick"</div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Mon, Jan 5, 2026 at 6:32 PM Peter Dzwig via Healeys <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>

<br>
it depends how accurate you want to be. According to Peter Browning's <br>
"The Works Big Healeys", talking about the rally cars he says:<br>
<br>
" The 1960 cars ran with triple 2-in (51mm) SU carburetters on <br>
individual inlet manifolds...[producing].. 180bhp at 5200 rpm.<br>
<br>
The use of triple 45 DCOE Weber carburetters in 1962 improved power <br>
output to around 200bhp at 5750rpm with a 10:1 compression ratio and a <br>
high-lift cam"<br>
<br>
I would get hold of a copy of Browning's book and go to the back and <br>
think about how far you want to go!!<br>
<br>
Hope that this helps.<br>
