It's just like the second air cleaner, 1965-71 Hi-Po Air Cleaner, except the
sticker is as I mentioned above.

It does not say Powered by Ford and there are no date codes stamped into the
tops of them.

I did, it's still somewhat difficult.

I'll take a look tomorrow.

I measured the stroke before I read this. I didn't think of a straw. I
used a new, unsharpened #2 pencil. Held it straight into the #1 spark plug
hole, leaned it to the right slightly until it rested against and in a
little nook of the exhaust manifold and marked it with a fine point Sharpie.
The difference between TBC and TDC was a hair under 3 25/32" according to my
calipers. So, it is a 390!

Ever since I got it back in September I've just been enjoying driving it. A
few times, I dropped the kids at school or picked them up in it. You should
have seen the crowd of kids it drew. Most of them telling us, "cool car"!
My kids about cracked their faces their smiles were so big. Now that the
Michigan Fender Solvent has been applied for the first time, she's put up
for winter and I'm just looking to see what I actually have. You have been
a tremendous help too. Thanks Max!
Making it all original is not my cup of tea. I skipped the hot rod phase
when I was in high school. My two brothers had hot rods, both mustangs. I
wanted a hot rod, but I wanted to go to college worse and I knew I had to
pay my own way. I'd been looking for this car for several years, but I was
not satisfied with all that I looked at. Then, I had a battle with melanoma
about a year ago and won! After that, I said no more waiting and being so
picky. I found this car and I had to have it. I haven't been disappointed
yet. Solid car, no rust, good paint. It's not perfect, you can tell it's a
driver, and that's the way I'll keep it. No trailer queen for me.
Once I know exactly what I have, I'll figure out what I'm going to do. I
may bore and stroke what I have and add some goodies, or I may drop in an
Aluminum block 427 sideoiler. I see you said you have some 427 stuff.
Watcha got?
