Re: [AMC-list] caspers rod is toast

Crap, I think I accidentally clicked SEND on a partial post. Anyways...

I don't think the aluminum six was ever available in the pre-64
Americans, and the oil filter won't fit, and I'm not sure a remote
filter would fix that. But it would be a good match if you could pull
it off, 100 lbs off the front of the car would really boost
performance.

Personally however -- I would treat an aluminum engine build like
actual Rocket Science. Unless you know it's running history I'd have a
GOOD shop inspect the block, those cast-in cylinders have got to be
really weird. They're siamesed too, right? So thermal cycling means
they are never round. This can't help sealing that tiny area at the
head deck surface. And would you trust a regular shop to get the top
of that block flat? Don't drop it on one of those sanding machines!

It's been 50 years since anyone's done anything with that motor -- I'm
talking partway out of my a** here because I've never so much as
touched one, but if the iron motor was a thing of mystery -- and it
was -- the aluminum one will be 10 times worse. NO WAY I (at least)
could build that thing by July and not be scared witless every time I
drove it.

But I bet a lot of the problems with that motor in it's day would be
easier now -- you would run the right coolant, you would do
maintenance 110%, seals and lubricants are so much better today.

(I did look at one of those oil pumps as a candidate for my motor, and
it would be easy to modify one to remote the oil filter without one of
those screw-on adapters. Basically, tap three? holes, two for hose
fittings, one to plug. But it's tight down there, I have 1" of
clearance between the brass 90 degree elbow for the outlet and the
suspension.)
