Wanting to run my dual carb set-up on my 235 6-cyl. in my '59 El Camino but carbs set way too high. There has to be others that have this set-up. Any advice or pics?
Have the intake cut down.That will give you some clearance.I am doing same thing on a 60BelAir with 235.Also might want to talk with Tom Langdon.He knows alot....
And side drafts, but those were one bbl carbs. Maybe find a pair of those bent over 2 bbls from an early olds V 8 or a stude.
What carbs were you going to run? If they are single barrels, you might be able to find a lower profile carb.
Having a hard time visualizing: Are the carb bases on the aftermarket manifold at the same level as on the stock manifold? Are you using the stock style carbs? What kind of air cleaner did the stock carb have on it?
This would be a good way to fix the issue, but these manifolds alone are in the stratosphere price wise. Tom Langdon has been a very big help with my 235 project. I'm sure he would have good suggestions. If you speak with him make sure to ask about the headers he sells. Fentons will need to be slightly modified to work if your going to use a Offy or simlar intake. Tom offers a header that will be trouble free. He also has the correct intake heating kit for whatever intake you decide.
Thanks for the suggestions. The carbs I have are mono barrels but I may need look into cutting that manifold down. The stock set-up from the bottom of the intake (where it bolts to the exhaust manifold) to the top of air cleaner is approx. 10". The Offy set-up measures 11" but that is without the air cleaners and that would put it tight to the hood. Is the 3/4" heat spacer under the carbs crucial to run on them? I'll know more when I take out the old and get this set-up in there.
those heat spacers don't have to be used on the offy, only on the stock intake because the carb is right atop of the area where the intake and exhaust manifold bolts together, hence the insulation or heat spacer for the carb.
A stock 58 235 Chev was the highest HP of any 235. The base of the carb measured 1/4 inch bigger than any other 235 carb. Find two of them, hehe.
Give Tom Langdon a call.#586.739.9601 He is a wealth of knowledge,who has been there done that many times.He is going to help me with my project(dual carb setup)for my 1960BelAir.Main issue is dealing with "clearances"or "the hood"
The Holley 1904 1 bbl that Ford used on 6 cyl in the 1950's-up is couple inches shorter and I believe it had the wider bolt pattern like the 235 Rochesters did, or at least some of them do. They made alot of different versions, so make sure you get a matched pair.
You must heat the intake, especially if you live anywhere that gets below 65 degrees. In warmer areas it's not necessary, but you might notice a slight stumble off idle. If you want to further solidify this statement ask either Tom Langdon or Patrick Dikes, both experts with the 6's. The reasons for the heating are clearly spelled out on their websites as well as many in line club pages. I'm currently using Patrick's set up which is a tube that transfers heat from the header into the heat chamber on the Offy, it works ok, but I have heard that Tom's water heating method is better. I just ordered the kit and will update on it's results. I see your in Col and if you plan on running it in the cold you will absolutely need to heat the intake or it will run very poorly. I would also highly recommend Tom Langdons Webber carbs, they are progresive and made to work together. I used Patricks "mild" cam and found an 848 head, went .40 on the block and have a header with 2 carbs. I'm using a stock dizzy and the motor pulls like a S.O.B.!!
Yes the Holley 1904 is short, only 4". And yes to matching them by list number. A mis-matched pair will be difficult to tune. These have a wet bowl cover and they are prone to leaking from warpage. If these look like they will work for you find the straightest carb bodies possible.
