I'm not really sure, but one thing I'd like to know, is why would you
want to replace teh Chryslers with the chevys?

Not saying one brand is superior to the other, but your mounting and
manifolds and trans bolt patterns are completely different,a nd I
would think that it would take a lot more work to change over the
engines instead of rebuild the 318's.

Are the 318's the old "Big Blocks"? if so, they are vertually the
same blocks as the the 383's, 413,s qand 440's, which would be easier
to overhaul and get the horsepower/torque you're looking for.

If the 318's are the later "small block" versions, they are the same a
block as the 360 and late 60's 274, and you might be strained on
getting the results you desire.

Interesting - not that I don't believe you, but as far as I knew,
MOPAR never built a big block 318.

Then again, I'm not all that up on MOPAR stuff unless it involves the
440.

Tom, Richard and everybody else. I DO STAND CORRECTED! The early 318
"A" was NOT clasified as a "Big Block" but rather a Polysphere (or
Wideblock) 318. Obviously not the same as the 318 "LA" which was
classed as a true "small block" but not the large 383-440 Big Block
either, even though it did have heavier castings and big block
"characteristics". But I'm still not sure if the 413 is in between
the 383-440's or if it was an over punched wide block 318.

Again I Humbly apologize.

You learn something everyday.

THANKS!
Tim

No reason to apologize - all those different engines of the day were
simply amazing.

There aren't very many "classic" engines, but certainly the 318 stands
alone as the best engine ever developed. I might rank the 220 slant
six as one and the 220 Silver Diamond International six as another.

Also considered - 327, 350 and the great 564 International/Ford truck
engine along with the 7.3 liter diesel.

I'd thrown in Ford's 260/289/302 as well. The 289 powered many cars,
large and small.

the 390 wasn't bad either. the 351 Cleveland was a good all around
performance engine, and tthe 351 Windsor wasnt' that hot but was a
fairly reliable workhorse.


hmmm, two completely different 351's

For numbers powered the GM 2.8/3.1 might be there.
I saw a car magazine (Car & Driver?) article about a year ago that
was titled something like "the top 10 engines of all time."
I remember the GM 3800 (maybe 3.8) and the Nissan 3.0 were 2 of them,
but can't remember much else.
I've put most of my miles on 2.8/3.1's, with 350's next.
