MarkT,
The Holly/ Weber 32/36 is a fine carb on the 235 with the Chevy cast iron manifold and adaptor + linkage from Langdon. I've set up many and have one on my 235 for years. Fuel pressure is an issue, too much being the case. However I think I saw where he's exhausted his supply of the Webers and is now selling the Carter Webers. The Carter / Webers that Langdon sells are a smaller CFM and will only be adequate in pairs on the 235. The issue with most 32/36's when you get them is jetting to make them run. It's not hard, just takes some patience.
