Inline six cylinder engine

poomshanka · Post by **poomshanka** » Sat Feb 18, 2006 3:56 pm

I need to get ahold of an inline six cylinder engine for a project I'm working on. It doesn't have to be in working order, and will actually never be used for its "designed purpose". I don't even need the "accessories", just the engine block, crankshaft, etc.

I was wondering what types of cars use/used these engines. That will help target my search, probably in local junkyards.

Apologies in advance for somewhat vague descriptions, but I really don't know enough to ask targeted questions. If there are any questions to ask that might help guide your response, please feel free to do so.

Thanx!!

Older Ford trucks and vans use them as well as Jeep.

Chrysler Corp (Dodge, Plymouth, Chrysler ) cars had the slant six from 1960-1983

The Chrysler Slant Six Engine (170-198-225)

I would try to locate a Ford 4.9 Inline six. Tubaryan is right when he says they are very common. The only other one that I am very familiar with is the older Mercedes. Inline motors supposedly run smoother...

Many of the old AMC's had the 258 inline six, same as the Jeep. Very reliable engines (except for the valve cover leaking and exhaust gaskets blowing) and loads of torque. Can also be "built" to put out as much power as an V8. People are practically giving away AMC's.

Trade show display. The crankshaft will be turned by an electric motor and will move the pistons slowly. Where the fan usually attaches, I might rig up a gear and chain system to drive another device.

This thing will be cleaned up and heavily modified - possibly chrome plated and/or painted, with lighting effects. Just a rough idea right now, but I need to get a handle on the engine block sitch first.

My 1973 Pontiac Firebird had an inline 6 and a 3 speed transmission. It was a good engine.

--Toyota Supra
--Lexus GS300, SC300, IS300
--Jeep CJs that had sixes were inline until this year.
--Some Volvos like the recent S80

many diesel pickups have inline sixes.

I would like to see the old Chrysler slant six get the attention it deserves.
Outstanding engines!

Jeep's 4.0 liter was an inline six. that would probably be your easiest find.

Every manufacturer has made inline sixes. General motors used a 250 cid straight six in many applications for decades leading up to the time of computer controlled engines. Easy to find in junkyards--look in old pickup trucks. I had one in a '74 GMC pickup.

The Chrysler slant six was popular and widespread, but its slanted configuration might not work in your application. Or, it might be an advantage.

Ford had several straight sixes up through at least the middle 80's, in two sizes up to a 300 cid "Big Six". I had one in a '84 Ford pickup.

American motors made straight sixes for decades, and that is the 4.0-liter engine in Jeeps. The only Chrysler engines in jeeps were V-8's, like the venerable 318 in the Grand Cherokees starting in the 80's.

Nissan made a straight six modeled on British six-cylinder engines for the Z-cars of yesteryear. I can't, however, think of a straight six made by Toyota, except perhaps for the old Land Cruiser.

If you cut up an old Jag engine, some Jag collector will come remove your fingers.

Most of the muscle cars and hot rods leading up to the 70's were also offered with straight six engines (including the 250 which was common in cars like the '58 Chevy). But if you cut up one from a '64-1/2 Mustang, you'll lose more than your fingers to rabid Mustangaholics. Be careful which junker you choose.

All in all, a Chrysler slant six or a GM 250 will probably be the easiest finds in junkyards.

The Cressida and the Celica Supra (mid-80's vintage, anyway) used the same I6 engine. Don't know if there are others, but I'm certain about this one.

I think the Chrysler slant-6 is the most visually interesting I6. And there are lots of them around. We had a Dodge Dart with the 225, that we drove 'til the suspension, though religiously lubed every 3 months and alligned annually, wore out to the point that it became unsafe; but the engine still ran GREAT.

Joe Baker, who agrees with everything else Rick says, but adds that the 64.5 Mustang is the ONLY one Mustang devotees will defend to the death; the later 200 I6 is often cast aside in favor of a small-block V8, even though the car has to be practically melted down and rebuilt from scratch to do it.

My 89 jeep cherokee has a 4.0 liter inline 6. Very reliable engine but it's horribly fuel inefficient, kind of a love hate relationship because I love driving the vechichle and I really like the power but I hate the roughly 13-15mpg.

Here's a nice little inline 6. It might be a tight squeeze, but think of all of the low-end torque!

I wanted to thank everyone for their input on the inline six!! After a visit to the local wrecking yard this weekend, I ended up with a short block Chevrolet. I think it's maybe a 230 or 250 - something in that range.

I'll be tricking it out in the next couple months, and for anyone that's interested, it'll be in Colorado the end of this June in our booth.

Don't wanna spill too many beans, but it oughtta be worth swinging by to check out - wild, fun stuff!!

Yes, remember that the Chevy "Blue-Flame 6" was the original Corvette motor! Parts and aftermarket mods should be available almost everywhere. Good luck!
