SU Carbs for 4.6 litre ?

Can I still drive a 4.6 liter engine with HIF6 o HIF44, or does it have to be the HS8?
I don't want to install weber or something else!
Regards Jorgen
 
Hi Jorgen,
Yes, just re-jet the carbs and all will be ok.
I started with the following setup, on a slightly tuned 4.6l:
  • Twin SU HIF6 on (almost) std manifold.
  • float level 60 thou
  • BBW .100in Jet Needle
  • yellow graded 8oz springs
  • Poppet valveless butterflies available from SUcarb.co.uk, Throttle disc kit WZX 1321
It was a little lean at higher revs, but this allows thinning the needle to suit. The engine is smooth, pulls cleanly and strong.
Gavin.
