Ive got fenton headers on a 261 with the stock intake manifold. I made a heat plate for the intake and was going to use water for heat and looking for a tidy way to run the lines I thought about the two 1/2 inch pipe thread ports on the headers. Has anyone used this to heat the intake? Would it be too hot? Any thoughts? Thanks in advance.

I had Williams headers( kind of a Fenton clone) on the 52,216. To start with I used heat from the headers as they were plumbed for that, I only ran one pipe and that is not satisfactory. You need to use two pipes allowing the heat to flow better. I ended up using Langdon's water heat and used hoses as suggested. Worked well, but warm up time is slower. Leakage around the plate was a problem but I found that a ridge in the casting in the manifold was causing the trouble. I used thicker gasket material and that solved the problem. I recall one CT member using copper or aluminum instead of hose and his engine compartment was complimented by the excellent work he did to bend and fit the tubing.

Thanks, yes I was going to use copper too. Heater hose even if its small hose seemed too big and bulky. Was just find it hard to scare up the right fittings so it didn't look too cumbersome. Do you remember where he ran the copper to?

I was also wondering about an air pocket in the intake maybe been hard for the coolant to flush out?

I KNOW they are rare, I KNOW they are scarce, I KNOW they are pricey, I don't need anyone to remind me, BUUUUUT, if anyone should run across one ------ in my opinion---------- a 6cyl Corvette exhaust manifold is the ideal one to have.

I will look today or tomorrow and see if I can find my installation instructions from Langdon. One hose hooks into the heater hose (hot) and the other into a plate located at the thermostat housing (return).The heater hose hook up was to a plastic fitting. Easy to find. The return hose situation may be a little harder if you do not have the kit, as there is a special plate that fits behind the thermostat housing.

I have Fenton headers but an Offenhauser intake running Tom Langdon's hot water heat system. I have a write up on an old website. I will try to link it so you can see how I did it.

As 2blu52 states, the lines fit into a spacer behind the thermostat and the other in the heater hose. I used copper tube, but a nicer looking build by a member here used the tubes from plumbing supply for sinks etc that are chrome plated. If I ever have to take mine apart, I will use that tubbing as it looks much classier than the copper.

I have an Offenhauser intake with the Fenton headers. I am not running any heat....reason why , prior owner ground the tabs off the intake when the intake was on the former engine. I was too cheap to buy new intake and decided I most likely could not make a U bolt or other arrangement work. Been driving for over 10 years without an issue here in the humid south. Intake does get cold, but no issues..maybe I'm lucky.

I have always looked at it this way. General motors is not known or at least had not been known to throw money around, so when they developed the intake heating system on their engines, with no options to shut it down depending on climate, humidity, and temperatures I felt that it must contribute to the drive ability if not the mechanical welfare of the engine itself So I have always tried to keep it functioning. If it works for you it works for you. Just never did for me. I operated my 52 in temps from over 100 to less than 10 degrees. It always bothered me to think that a lot of raw gasoline might be finding it's way to the crankcase with out it.

I hear you, and am not happy with circumstances, and my car is a little rich based on tail pipe black color. I've toyed with running copper tubing from each side of header and lay along bottom of intake. I would need to use stainless straps to hold tubing against bottom of intake. But that's for a much colder day, it's 90 degrees and climbing. BTW the heat index is currently 101

Fenton made a cast iron split manifold with the heat riser cast into the back half. About as easy to find as that Corvette manifold. But still out there. Also a company by the name of Hollywood Deep-Tone made a split header with the heat riser welded into place. Both worked really well.

I purchased 3 kits from Fenton in the 50s. two for Chevrolet and one for a Plymouth. All were split stock manifolds and I had to send in my old ones as cores. Cost delivered to the front door $25.00.
