170 cu. in. interceptor inline 6 exhaust manifold

Looking for an exhaust manifold and riser for a 170 cu.in. Interceptor (Ford) inline 6.

I do have some misc "Interceptor 100" parts. I'm pretty sure I have one extra manifold, but was planning to keep around as a spare for my 64. (plus to keep Pete happy...knowing I can take off my shiney exhaust and put it back to stock. ) I Will try and check thru my stash this week.

Hey thanks so much guys, JBear, Steve but a scrapper in NY (not of this forum) got my ire up so im just fabricating my own. In retrospect a much better option anyhow.

Thanks!!

Thanks Mark I'll give that a look!

Hi, Pete (hope that's ok) it got pretty convoluted quickly I've been in a few restos before so bumps in the road are half the fun. BTW my father (92 years old) is a retired mechanical engineer and my daughter is off to college next year for electrical engineering.

Well, like anything when your buying a project your getting a project. I partially tore down the engine and had some concerns as to the emphasis the previous owner placed on not laying the boat up properly the last time the ran it and "it never saw salt water".

So I attempted to remove the manifold several of the bolts were steel so electrolysis and rust would not let them loose. I then broke the head loose with the manifold still attached and to my horror found a huge crack running the length of the jacket, no big deal at that point, just a hidden surprise. the head had multiple cracks, again not a huge concern. A chunk of valve missing on #2 cylinder and a pushrod bent into an "s".

So I suspect, well no am sure the boat had been sunk and possibly while running, appears to have been hydro locked, then they tried to deal with it and it probably wouldn't run so they gave up. Then put it away.

When a friend of mine and I had finally managed to cut the manifold free, removed the riser and end cap we discovered most of the interior was gone. To the degree that we literally poured corroded aluminum on the ground, the riser was pretty much done as well.

He (my buddy) is a very accomplished welder, certified to weld airframes and does a lot of specialized work on cast metals. Remarkable work he repaired a head from a Kermath inline for us several years ago that was deemed unrepairable by the first people my cousin consulted. He only saw that one in my basement by chance and came back with it 2 weeks later. Looked factory fresh. Repaired an exhaust manifold we found in Bracebridge Ontario for the motor for us as well.

So long story short, just was too degraded on a material level. If it were just cracks, broken pieces that could have been replaced it all would have been good. It wasn't too far away from paint holding it together. Oh had a hole where the battery burned through it on the bottom. I think they tried to burn the boat after they swamped it

I think the block will live though fortunately if not I know where I can get a comet engine.

Retraction on my last post! old one was cast iron I was surfing and apparently had aluminum on my mind!
