FWIW, I took Steve's advice on this radiator set-up last year and have been
VERY happy I did.
As well, when we were heading up to TU in Big Bear we got stuck in some
construction traffic coming up the hill. While idling for some time the car
remained very cool. (Noteworthy here is that my mill is bored-out at least
30 over by the fellow who reassembled the car in 1986, running a mild cam
and a too-big Holley four barrel.) Interestingly enough the gentleman we
were following had an aluminum radiator in his car. He started puking
coolant while we sat there waiting. My car never did. Temp gauge got up to
about 240 before traffic started moving again. Once at speed, dropped back
down quickly to about 190.
Steve, as usual, my compliments to the rocket scientist!
Now I did notice a bit of a problem with number 8 plug when I got
back.....very oil fouled. I am hoping it is a cheap manifold gasket that is
the problem, but have not had a chance to check it out as of yet. If it
aint the problem, I am just gonna keep changing plugs until I have a problem
similar problem with at least three more cylinders.

Frank,
Your questions:
1) 260 vs 289 block. Yes, they are the same generic type "block", but the
cores
for the water passages are very different. While both are "thin-wall", the
wall
between the bore and the water is about the same thickness, but the bore is
0.2"
less on the 260. So, a 0.030 overbore gets the piston to about the same
distance
from the water in either case. There is NO extra thick wall on the 260's
that
allow it to be bored to 4.00" (0.200 overbore). Anything else said is just
plain
dumb luck about the centering of the casting molds.
2) An 0.030 overbore is not a bad thing. Many rebuilders got to 0.060 (and
that
is NOT a good thing).
3) You will be very unhappy with a 4 row in that price range. A good
Modine, with
the high fin count and densly packed tubes should cost about $300, and is
well
worth it. Saving money here is wasted. Only other option worth considering
is a
2 row aluminum radiator, which is more expensive, thicker, and requires
custom
shrouds and does not look stock, but works very well. The 4 row Modine fits
your
stock tanks.
See my previous "cooling" postings on all the things you can do (with an
engine
that has no sefere illnesses). If you don;t have one, right back and I'll
send
you a copy.
Steve
