235 intake on a 216

I bought my car with what appears to be a 235 or other intake with a 216 rochester B. The throttle body was modified by cutting a slot to the bolt hole to fit the stud spacing. I have never heard of this being done before and can only guess that this was done because these were the only parts the guy had and maybe a lack of cash. Is there any benefit at all running this intake over the stock 216 and would I be better off either buying a 235 throttle body (if possible) or a 216 manifold? I was also debating installing dual carbs but don't know if the 216 would benefit from that. Any thoughts would be appreciated.

The 216 can most definitely benefit from a dual carb set up.
Dyno tests in the early Fifties (by both Roger Huntington and "California Bill" Fisher) showed a 12 HP increase on otherwise stock engines. When you're starting with only 90 HP, this represents a HUGE increase. Better fuel distribution is the main reason.

If at all possible, land a manifold with broad, sweeping bends (such as Edelbrock, Tattersfield, Edmunds, et.al.). Good luck though. These have become golden in the last few years. Any two carb is good, however, and the aforementioned dyno tests were performed with a McGurk and a Nicson, both which feature right angle bends (as do the re-pop Offy and Fentons).

BTW, my maxed out 216 does great with 2 94's on an Edmunds 2x2.

 

Thanks Mo! Sounds like my next step will be acquiring a dual carb intake. Do you know the size of jets required? I have a spare carb that has a 56 main jet.

 

As long as you're running a matched set of carbs. Stock jetting will be fine.

 

without a doubt.

The small pattern is much more common.

I don like rochesters. they tend to leak are as far as i am concerned are a poor design.

I prefer the strombergs, carters and holleys.

 

thanks guys!
