Jon, as this is a Ulsteroid special I would personally go with Henrys suggestion, there are alloy inlet manifolds on the market that are right for the job. The ALR for a semi downdraft SU would be perfect, turn it upside down, Fit a 1 1/4" SU, get a spacer turned up to lower the float chamber about an 1'', fit a blue spring and number 5 or 6 needle (dependant on engine tune) you will be very happy with performance.
