Rebuilding the Inline 6 Heart of a classic Ford Mustang. Refreshed, Rebuilt, and Ready to Run!

We're often brought projects that people have had in their families for years, even generations. Either vehicles they themselves purchased and just couldn't get running correctly or something they have inherited that they would like to see back on the road to keep making memories. Either way, we're always here to help!
In the case of this classic Ford Mustang and it's Inline 6 heart, it was leaking and smoking from just about everywhere it could leak and smoke from. What initially we had hoped would be a simple disassembly, cleaning, regasketing, and ship it turned sideways on us when we discovered there had been a previous questionable rebuild already done. So we had 2 options at that point, put a bandaid on it and hope it held, OR, do it how we always say.
Do it right, Do it once. So, let's get to work!

Ford straight sixes are nearly indestructible. Lifelong Ford guy have had a few of them in mavericks and pickup truck. Keep the oil changed and they will run virtually trouble free for a long, long time. Great job Rich and awesome video. It takes time to rebuild an engine. I rebuilt a Ford FE 390 for a friend of mine years ago. It definitely takes time to do it right. Well done.

It is nice to see old-school engine rebuilding vs. just slapping in a crate motor.

Nice rebuild, pity whe missed the final product and first start-up.

thanks I really enjoy your content

Austin if you’re going to put input in on Rich’s work. He’s going to put you to work. It’s great and loved the build! 💯👍👊

On another site, the rebuilder threaded two old headbolts with the tops cut off into the block to use as temporary dowels to keep the head gasket lines up while he started some of the real headbolts. Seems like a really good idea. Your thoughts?

Rebuilt one of those back in 1992 for my sister-in-law's 1964 1/2 Mustang.

[@andrewstoffel1170]

Would have been nice to see the result of all that work. 👍

I know the feeling. I've an old 1996 Dodge Dakota & Dodge stopped carrying parts after 2016. With an ever less availability each passing year in the Aftermarket. Just not enough of them on the road still to warrant making parts unlike the common well known classics 😔 What are we going to see next? Hopefully that TA you passed by.

that same seal is used on Olds engines.
there are a million straight six engine parts vendors out there.

[@meganar9096]

What was the part number for the upgraded rear main seal? All I'm finding is rope seals

[@RobbyGerken]

Not sure if you will answer this or not. But I have the same motor and I remember my dad, 30 plus years ago working on it, saying it was smoking, and that's where he left it. I opened it up and found these. Can you tell me? Is the motor worth rebuilding?Or what these are. 0:25

The vast majority of early 'Stangs' had inline sixes.

[@HenryCaulk]

Were you out of. My 66 ford mustang inline 6 needs a rebuild pretty baddly

[@ivancastro4723]

What carb did you guys go with?
