Smart move going with Langdon on the heat plate. By the time I was all said and done I had more into my home-made plate than his pre-made one would have cost.

For the heater lines I did mine like this:



I got new heater hoses, went through the fender, ran them to the brass T with hose barbs threaded into it, and ran one set out behind the engine and the other into the heater core. Works really well and everything is nice and tight. Plus it opened up a lot of room on that side of the engine bay.

...and I think the brass looks pretty cool which is always important in these endeavors.

It really tidied everything up by running the lines behind the engine. If you get the lengths right you'll clear the headers and linkage just find. Word of caution: Make sure there's no interference with the linkage no matter how you run them. Mine got hung up once when I was testing everything out. Ended up nearly wrecking the car! Got stuck at WOT and would not let go until I shut the engine off and physically moved things around. Really scary.


I had a tough time sealing my heat plate to the bottom of the intake. After trying RTV, etc, I ended up with a combination of RTV and a rubber gasket I made. Another trip to Lowes and I got this:

I then cut it to match the opening and OD of the heat plate, punched holes in it for the bolts to go through, and RTV'd it top and bottom between the heat plate and intake. It's the only way I could get it to seal. Now that it's on and not leaking I'm NEVER taking it off!

Pic of it on the intake:



Couple of things to note: Notice how I trimmed the ears? That's because the Langdon headers were interfering with the Offy intake. I split the difference and now they come close to touching but I left about 1/8" clearance between the two pieces for expansion/contraction. Also you can see the "plugs" on the bottom of the offy that I epoxy'd closed. Literally just sealed them. works really well and no leaks. Now the brass fittings: they're much larger than Langdon's. Probably didn't need to be but I didn't want to mess with reducing the hoses. Heater core still gets plenty warm for winter driving and intake seems to be working well enough for now. I might look at throttling it down a bit this summer but it's fine up to about 70 degrees ambient so far.

Finally in the first pic you'll see the Offenhauser and emblem look like a different color. It's bare metal. I painted the whole thing and took a file to the raised letters. Nice little trick and really sets it off. Looks like it could be stock but isn't.
