carbs are close together but again are centered. If you use an alternator there is
ample room for everything. Van Pelt has the alt bracket too. Used this setup many
times.
Google that 8BA Offy intake.

Charlie, thanks for the input. I like the 1075 intake better due to the centered carbs, but since I have an earlier block with a different breather setup, I didn't think this was an option for me. Also, aren't the carb mounts tilted slightly on this intake to account for later canted engine mount?

On a side note, do the head mounted water pump pulleys and the block mounted water pump pulleys line up?

Yes on both questions. I see that the Speedway fan pulley is discontinued.

Yes, to your question on those pulleys lining up.
In my mind, the beauty of using a stock generator on the setup you have, as either a generator or converted to Whitney style alternator, is that all of the single belt pulleys will line up, plus the front bearing system will safely withstand the load of a pulley with fan mounted. I know there are those saying they have mounted a pulley with fan on a regular alternator, or on a powergen with success, but I also know of some of these setups that have failed, and some failed unsafely.
