While it sounds good in theory, and granted bigger runners would help, I
think you'll find the main restriction at this point would be the wimpy 150
Stromberg. Now a large runner manifold modified to take a single 175
Stromberg would probably be *almost* as good as a twin 1 1/4 SU setup. I
believe that the intake manifold with the larger runners is off a late MK3
and MK4 Spitfires and possibly very early 1500's but I'm not absolutely
sure. One of the best manifolds and setups I ever had was a custom one off
manifold sporting TWO 150 Strombergs. Wish I still had it. Marvelous
welded up aluminum piece. Unfortunately, it succumbed to vibration, plus
not being supported properly from underneath, cracked beyond repair and I
no longer have it -

>This discovery of there being two different sized manifolds for the single
Stromberg is something I think we should try to figure out. There's a lot
of performance increase potential in this,
