Just a last thought make sure you heat the new intake. Tom recommends going with water instead of exhaust for heat, so whatever you decided make sure it is heated. I purchased Tom's set up. The Carter/Weber progressive carbs. I have it installed but not yet fired up.
I have the Fenton intake dual single bbl. with the 1 x 2 carb adapters on my 235. I just ground off the 2 mounting ears that was not used to mount to the Fenton intake. One thing I had to do was make a custom bracket so I could hang my bypass oil filter, not sure how yours is now or if you even have one, I just did not want mine on the fender well or fire wall.
