Pic request 1800 intake

[CajunMike]

Anyone have a decent pic of an 1800 intake that specifically shows the water choke port or could someone take a pic of one and email it to me? Front, back, and side where the port is would be optimal. I have an 1800 with no water port that I need to drill and tap.

Thanks

Not what you need, but hope it's a start. This is the single plane manifold that I got forom Jon Logan a few years ago. Getting ahold of a gasket may be helpful to you, as well.

Thanks Danno, that gives me a good idea of what is on the head side, just looks like a plain old drilled hole for the water port.

Here is what I am after. Im trying to figure where to drill and tap with my barbed connector. This is a pic of the side of the 1800 manifold. Item #1 is the thickest part where I could tap through, its about 5/8" thick. A hole here would put me near the top of the water outlet and my barbed connector would thread through about 1/3 of the way. Item #2 is the thinnest part of the intake at about 1/4" thick. Tapping here would put me in about the lower middle of the water port and my barbed connector at the threaded end is a little longer than the thickness here (so I would maybe have to shave off a thread or two to get it flush). Just looking for some input as to exactly where the port is located on factory drilled specimens. Any help is appreciated.

Hi,

I have a manifold like yours. Instead of drilling the manifold I used a water tee in the upper heater hose to supply the choke. The tee is off a 80 fi spider. The tee has two 5/8 nipples for the heater hose and one 5/16 nipple for the water choke.

If you need a tee I might be able to find one.

Thanks for the reply Ralph good to know that the heater tee will work. It was suggested to me but I wasn't convinced it would work. It's just a straight loop from the heater hose into the choke and then the hose out of the choke goes back into the head using the original water line? I'm pretty sure I can get a tee from Grainger supply here locally now that I know the size but I'll let you know if I may need one. Is it a metal barbed tee like brass or stainless or is it a high heat composite?

I may still do the tap though as I eventually want to install a water fill tee at the heater hose so if anyone else has pics or suggestions on the tap id appreciate them.

Thanks,
Mike

It works, you can run it from the metal pipe (under the ex manifold, where it runs on Spider 2000's and late 1800's) to elsewhere on the motor. I've used an FI coolant "T" which is tapped for a plenum heater. Run a hose from there to the choke and from the choke to the metal pipe. Works great and keeps you from drilling.

I'm with Brad, the FI coolant tee is also a great idea.

A side benefit on not having a nipple in the manifold is that it makes it easier to get to the #4 cyl. intake manifold bolt.
My tee is just stamped steel, I'll try to take a picture tomorrow.

Ok I'm a little fuzzy on this. I've seen the fi tee so you install this at the radiator hose connection in place of the existing tee and run a hose from there over the engine to the choke in then the choke out runs back to it's original location? Just trying to get a mental image of this.

Sorry not the tee but the fi coolant neck. I'll take pictures tonight.
