Yeah, I'm aware that moisture is the problem, and I know about the hows and
whys of galvanizing. I had in mind something a bit simpler...
(altho I have anodized aluminum at home before. :-)

I can remember a couple decades ago I used some stuff that was 2 part...
You mixed can A with can B, poured this juice into the tank, and sloshed
it around for 10 minutes until it started to set up.
It seemed to work pretty good, but I can't find anything similar anymore.
Something like that was what I was hoping for...

If I can find my Grainger catalog under all this other crap, I can probably
find something good in it. I've got an account with them.
I just don't really wanna buy a whole quart of high $$ epoxy coating to
do the inside of a 2 gallon tank.. )-:
I'll probably just buy a sh!tload of fuel filters.

Yep, even bigger if You coax it and feed it plenty of O2...
Rust is amazing stuff, ain't it?! Natures glue, and natures solvent, all
Did You know it never sleeps? Err, at least I heard that somewhere...
Oh well, thanks for the input!

A C6 from a FE352/360/390 truck should drop right in... All FE's used the
same bellhousing pattern. Dunno about drive shaft lengths.
> ...are competition/performance heads available? Any suggestions?
You betcha! Edelbrock makes a nice set of aluminum FE heads for
352/360/390/427, but they are something like $1400.00(US)
But wait..! What FE heads do You have??
Some FE heads breathe plenty good!!
Early (1958-65) FE head castings have the same basic ports as 428CJ heads!!,
and dressing these heads for the larger CJ valves makes them functionally
equivalent to the 428CJ/SCJ heads.. These heads breath plenty good!
The combustion chambers are larger (4cc's?) than later heads, so You
may need to have them milled a bit to bring it back up.
I've read that .020" = about 4cc's on these heads...
66-68 heads heads start to show the "downsized" intake ports, smaller and
lowered exhaust ports, and then air injection bumps and stuff...
What casting #'s do Your heads have? Look between the 2 center spark plugs
on either side for casting #'s....
I have a set of C1AE heads from a '62 FE352 sitting in my yard, and they have
the most *amazing* beautiful big ports.. These can be made into clones of
the 428CJ/SCJ heads with a simple change in valve size.
They's goin on my FE390 one of these days.! (-:
Let me know what Your head casting #'s are. You might have good stuff already!
I have 33x12.5 radials on the stock, 1970 F250, 16.5x6 rims. After I
bought them I found out that they were not recommended for rim widths
smaller then 8" ( thanks tire store ) They seem to be working fine. ( a
little too much crown which will probably cause them to wear a little
too fast )
A wheel widening shop told me that there was a factory stock rim that
was 16.5x9.75 has anyone heard of such a wheel ( 8 lug )
