I had an '88 Dodge Ram d150 with the V6 (basically a 318ci with 2
cylinders lopped off). It ran great but the body was rough, so I sold
it for $100 more than I paid for it and bought a cream puff '87 Ram D150
with a slant 6. This second truck had 80K miles and was garaged since
new, no rust, very, very clean and nice. The slant 6 was fine for the
hauling and towing I had to do, but that V6 sure was smoother. Well, I
guess it's a moot point since you can't even get an inline engine in a
Dodge full size truck anymore.
Since I am the original poster of that reply (6 mos ago), the argument was
about a V6 design, not an inline design and I am also a proud owner of an
'04 CTD. Of course that also excludes the slant six as well. On another
note, the slant six also had a nuch weaker bottom end in comparison to the
GM and Ford equivelents. (5 vs 7 main bearings) This however was not an
issue at stock power levels. As for not seeing inline engines as much as
before, I am afraid it is because of packaging restraints created by
today's compact body styles.
There was nothing weaker about the bottom end of a slant six. It long
stroke with a small bore required a different main bearing arrangement
to keep engine compact. It had less bearing but the ones it had were
very healthy and sturdy and nothing cheap in their design at all. The
old slant six is likely the most durable 6 ever built and emmsions
killed it off, not bad design. I owned a few slant 6's of the 60's era
in the early to mid 70's and they were fine smooth engines and powerfull
for their size too. Back it 74 when I was redeploying to another base in
my 66 Cornet with a slant 6 I ran it across about all of Oklahoma at 90
MPH plus in summer heat with no problems. One fine motor.

I'll agree about the "leaning tower of power" being a STRONG engine.
I consistently revved my '63 170 over 6 thousand RPM, where it
delivered 206 HP (dyno verified) to the rear wheels through a
torqueflite. This was not a weekend racer, but an everyday street
driven engine. It was still going strong at almost 200,000 miles on
the original stock bottom end when I sold it.
The '69 225 would not rev much over 5 grand, and was not nearly as
highly tuned, but I drove that Dart across Montana at 104 MPH back in
Well, the slant 6 in my Ram wasn't that unsmooth. It was alright I guess;
it ran great (esp. after replacing the plugged up cat converter). Besides
the '87 Ram D150 with a slant 6, I also have owned a '64 Dart 170 with a \6
bought from the original owner in '95 for $700 with 90k miles and ran
wonderfully and just had a faded paint job. I should have kept it and
painted it instead of selling it. Stupid, stupid mistake. I also have
owned a '72 Plymouth Volare that I bought at a charity auction for $300.
That was a wonderful car -- 70k miles, white 4 door, plain jane low option
car that was unmolested. It had no carpet, plain small hubcaps (original),
radio delete (it still had the plastic cover that Chrysler put on cars that
didn't come with a radio) but it did have the auto tranny (the only option
Driving the '72 Volare 4 door was like driving some sort of municipal or
gov't car or an unmarked detective's car or something. It ran perfectly
after a full tuneup, but the cylinder head cracked while my sister was
borrowing it. I gave a mechanic "friend" of mine $1000 to install a
rebuilt head (that he could get for $200 from an acquaintance of his) and
while it was apart, do a ring job/rod bearing job, change gaskets, flush
the tranny, etc.. But instead of doing it that way, he just tore the head
off of an old Duster in his friend's junkyard and put that in my Volare and
then he just pocketed (stole) the $1000, without doing any additional work
on the Volare (rings, bearings, etc.). The Volare ran like crap after he
worked on it and had coolant/oil mixing. I was pissed and never did get
that money back from him. I sold the Volare, in disgust. But I'd like to
pick up another '70's Dart or Volare 4 door or even an Aspen.
Ya know, it's funny that, years ago, engineers from the current owners of
Mopar (Diamler / Mercedes) don't agree that the /6 lower end is weak . . in
1960 they said the entire engine was the best engine ever designed. And it
was the most produced of all the Mopar mills
Now, having personally taken 3 slant sixes over 100,000 miles myself (160K,
350K and 285 K), I think you're full of bull about the weak lower end.
By the way, a inline six is about the same length (except for the slant six
which is about as long as a V-8) as a V-10, give or take a couple inches.
And a whole lot narrower.
Ah, he finally got it broken in. Darn near as bad as a Cummins on break-in.
I got worried, for no reason of course, about my first /6 so I overhauled it
at 166,000 miles. It had been a well maintained car owned by a vacuum
cleaner salesman and when I miked the journals there was less than 1/2 of
1/1000 of an inch wear. Bore didn't even have a ridge, so I honed them,
popped in new rings, bearings, timing set and a rebuiilt milled head
(0.090"). Then I installed a low restriction exhaust and rejetted the carb
(the big BBS single) and started kicking some 2 barrel V-8 butt.
yea we loved the truck and had not a minutes problem out of the engine. but
we needed something a little bigger and more family friendly so we sold it
and bought the 99 v10 (what a differnce in mileage).
thats about the size of it....but it was fun =)
last ride to the dealer to trade the v10 in on the 05 ctd my brother in law
rode with. floored it from rolling start @ 70 scared the sh*t out of him!
