you MIGHT- depending on things- want 90degree or 45 degree barbs if you are running FI ex manifolds, to more easily route the hoses away from the cast iron....make 20 & sell them here.....

Where do I get a bored machinist friend with lot spare time looking for one off little projects to do for fun? Around here machine shops dont want to talk to you for less than $100, actual project in reality requires lot more pictures of old Ben, plus you are on bottom of their priority list so expect long wait.

I usually end up cobbling up something with welder at home. May take me lot time to reinvent the wheel, but price is right and I still probably get it made and in use before a shop would get around to my project.

Here is link to progress:

The problem I am now having is determining the size of the two bolts that are closest to engine block--ANybody know what diameter they are (not the hole in gasket which is same as part I made--but the threaded part?)? The single hole away from block I have a bolt for but the ones nearest seem bigger than the hole in my stock gasket--I am wondering if they are just not long enough to reach to the threaded portion up inside the intake? I have misplaced my OEM bolts that held exhaust mani to intake mani so I have no reference.
If Abandoned Bronco is reading this--what size were yours? Thanks DOUG

PS--Would love to provide them for everyone that wants one but unfortunately they are a victimof too low demand and too high production costs. Unfortunately that works for Ferrari and Lambo but prolly not for us "big spenders" on Fordsix....... :(

P.S. 1/2" aluminum plate is high but I will check with my friend though and see what it might take to produce them in some amount of bulk--Ya never know.... DOUG

Hey, sorry I missed this earlier. Glad the suggestions helped, it looks like that plate should work out just right! The only thing I might suggest (and only time will tell) is to put some piping to get the hoses further away. Those rubber lines are going to be right above the exhaust manifold and may start to crack due to heat. Fortunately, you already have the threads, so you could just buy some piping at a plumbing store.

As for the bolts, all three were exactly the same on mine. I never kept track of which was which and never had a problem with one going in and another not, so they should all three be the same. If you still need, I can track down which size they are by running them over to a parts store. Let me know! :D

I am thinking that ideally I would like to use flexible 1/2' copper line on it--I tapped it at 1/2'NPT so I can play with it re: fittings. My "back" (near block) two bolt holes are def not same size as "front"(away from block) one. Holes are much larger--actually larger than the holes in the gasket from which I made the plate.

The only other possibility is that the hole they go into is threaded deeper in there--I will have to try to get underneath and look--difficult to feel.

But when I put the same size in the two as the one they just spun and were too small dia.

Will look into it more. Letcha all know...D

Why do you want to heat your intake? What am I missing?

off idle stumble due to too cool air--no stovepipe heat from exh manifold--lotsa condensation when cool-will prolly freeze in winter. Got efi heads--need to heat cavity under carb on intake since stck log is off.

Do you think it's possible that the threads pulled out near the end of the hole? If the holes are larger than the gasket itself, something definitely isn't right.
On the other hand, your bolts just may not be long enough. IIRC, mine were about four to six inches in length. I'll take a look at the manifold when I get home, since it's sitting in my garage.

Then why all the fuss about "Cold Air" intake units? Hood scoops and the like?

If I understand it correctly, you want the air going IN to be cold, because it's denser and you get more oxygen in the same space. Thus, more bang for your buck.

However, you don't want the carburetor to be cold, or you'll get poor fuel atomization, sluggish starts, less gas mileage, etc. The intake heater doesn't heat the air going in, it keeps the carburetor toasty so it can better mix the fuel with air (or better yet, cold air from cold air intake.)

I understand that :) But I've NEVER seen a cold car on our inline 6' sunless they were on a 300 away from the exhaust system...

Nah. I made 50 oil filter holders me & this other Triumph hoolie figued out- for post 71 Triumph bikes, uses a BMW bike filter, & fits in the oil-in-frame tank.
If you have a drill press, all you need are the neatly cut out blanks. Make a pattern to drill the bolt holes, & a bit/tap for the lumbing fixtures.
We fabbed up some jigs, and made a stack of them, & sold them to OIF Triumph pilots.
Required a LOT more workthan these water heater plates.
Still got 2, in case I come across another couple diehards.....

Pretty sure no threads pulled out--it was all good when I took it apart.

This is what I am thinking--maybe they need to be about 4-5" long--did not try that as ran out of time to really inspect but figured it is prolly something like that. I think their is a fitting or something they go through that is larger than the bolt hole and the threaded portion may be substatially deeper in there.

I think Where as the single hole can use a 1.25" long bolt because threads are just above where gasket will sit, the inner two closer to block need longer bolts to reach where threads actually begin--the end of the hole is larger than bolt and unthreaded?......thanks AB for your time and help...

AND re: heated intake--YES the carb/intake needs to be warmer for it to run right. Mine actually runs a good bit of condensation down it and hisses on exhaust when it gets below-55 or so degrees....

Airplanes have a little lever called "Carb Ice" that essentially opens a heat duct off exh to the intake/carb to heat it as they gain altitude (cooler air) to prevent this condensation from freexing and "icing" the carb...
