Looking for installation tips, suggestions, diagrams, pictures (whatever) for installing a water heater to my stock intake. #WinterProject

Considering this one from Raso Ent. > http://www.rasoenterprises.com/index.ph ... r-products

*update: the concern is because I'm running MP headers that do not supply heat to the intake.

Thanks in advance,
-Chris

What are you using for your exhaust? The description says it can be used with OEM exhaust manifold but I just don't see that happening. One other thing, if your intake has EGR, you'll need to remove that and plug the hole or you'll have a water leak into the intake. Other than that, it looks like a very simple idea/install.

Good catch @Badvert65, I forgot to mention that. I'm using MP tube headers (so I think) on a '68 Barrcuda.

You could buy one of those plates on ebay for closing off the stock exhaust manifold stove, then have a buddy weld up a box under it and weld in 2 -3/8" pipe nipples... then you could bolt it under any stock or offy manifold with headers... plumb the hose as you see fit (part of the heater core circuit or off the pump and head)...

I bought one of these ebay manifold heater block-off plates, and can recommend it just as DI suggests. I'm putting it on an Offy 4-BBL manifold with dual Dutra duals so I don't lose the manifold heat option. It's a robust piece and fits perfectly. I'm going to drill and tap it for some small-ish pipe thread, and install street elbows so all plumbing faces rearward (for a clean appearance). It will be tapped into the heater hoses. I was going to send a real photo, but it is buried somewhere in my mountain-o-parts awaiting installation once the head gets back from the machine shop. The current auction number on ebay is 322259701801, which includes photos. It was cheap, shipped fast, etc.

Thanks for the info everyone, I was not familar with the blockoff plate and will probably take that route. Just a couple final questions...

1. Do I just "T" into the heater return line?
2. Are one-way valves necessary/available to ensure circulation?

Have a great week everyone,
-Chris

I would plumb the heater hose lines so that the hot line coming out of the water pump to the heater core goes through the intake heater before entering the heater core (what's more important, your warmth or the intake's warmth?). No valves needed, just put the intake heater into the line, one in, one out, 3/8 NPT fittings.

I would use silicone hose at least on the sections to and from the intake heater box, as they are close to the exhaust manifolds/headers.

Here is an example thread: http://www.slantsix.org/forum/viewtopic ... t=hot+spot

somebody can correct me on which hose to use, but you want to use the hot hose that goes into the heater core, run that through the intake heater, not the one that returns from the heater core...

Route the hose coming out of the cylinder head to the intake manifold heat box.
Then go from the intake's heat box to the heater core.
The water pump is sucking-in coolant, from the heater core so you can leave the current heater core, to water pump hose, as-is.

You will have to see how much heat you loose from your in vehicle heater system. You may end-up changing to a hotter thermostat to compensate.

Thanks Doc - that's the answer.
