If you couldn't have the 258...
« on: September 29, 2009, 05:44:17 PM »
If you couldn't have the 258 what other engine would you rather have in your Eagle?

A Diesel? An EFI...DFI?

Assuming you mean the AMC-designed inline six never existed in any form, and the AMC/Jeep 2.5L four which came from the six could never have been . . but Eagles still existed, somehow . . it would have to be the AMC V8  8)

 . . or a Mopar small block V8, since it has a decent aftermarket, or even a Mopar slant six or the Ford inline six(if it could be made to fit!). If I could get it, an Aussie Chrysler hemi(yes HEMI) inline six from the 70's Valiants(impressive power to weight, some aftermarket parts), or a modern Aussie Ford inline six, which is an all aluminum dual overhead cam 4.0 liter and is in Ford Australia's Falcon up to this day(MPI, some turbo'd, insane power for the light weight - I'd love to build a '65 Stang with one of these engines in it). Why oh why don't/didn't we get these engines here in the US?!

For a Kammback, maybe even a turbo VW inline four(but what trans?), or a (gasp) turbo'd Saturn 1.9L(which can be mated to an Aisin AX-5 or AX-15 using Jeep 2.5L or Dodge Dakota 2.5L four bellhousings, respectively . . oh, but that four banger would never have existed without the AMC-six, darn)

Diesel? Maybe a CRD from a Jeep Liberty could be crammed under the hood(width issues?) I don't think a Cummins 4BT would fit unless the Eagle was solid-axle'd up front and pretty tall.

Briggs n Stratton, anyone?

Ok, I guess I left out the GM 4.3 V6, or (ugh, sigh) the ubiquitous, all too common, but overall ruler of the aftermarket engine swap: GM small block V8, the modern all-aluminum version, even better. Vortec 4200 I-six? I haven't been up close with one.

I agree. Another good choice would be the GM 292 straight-six. It was a truck motor and had the low-RPM torque curve of a 258.

D'oh, I completely fergot about the GM "dump truck" six. Good engine, wonder if it could be made to fit, it was a big tall engine.

How bout a good ol' Chrysler/Plymouth/Dodge/Desoto flathead six? It is my favorite old engine, but it has no place in a modern vehicle like the Eagle. Hah . . modern.

I'd have to go with a modern Mopar 4.7L (287 c.i.) V-8 found in many newer Cherokees, Durangos, and Dakotas or a 5.9L (360 c.i.) Straight Six Cummins Turbo Diesel. An AMC 304 or 360 would be awesome too.  :)

I'd have to say the cummins. I'd probably go with the 6.1 though, just to say I did >:D

but seriously, I'm actually thinking, one day, have a mildly built 4BT(4 cylinder cummins) in the eagle. thanks to Eagleneer360 who came up with the Idea though.

I think I'd have to go with the 4.1L Grand National engine or the 3.8 Turbocharged engine. Another GM engine I'd go with like txjeeptx included is the 4.3L but instead the turbo'd version that came in the Typhoon and Syclone.

Cummins = 4 Cylinder ISF 2.8L - 160hp @ 2600 rpm & 442 ft-lbs @ 1300 - Dry Weight = 470 pounds

Just for the heck of it, if I had money, time and more knowledge... Subaru 2.6L (stroker) GroupA/Raptor Supercharged H4 coupled with the 4 EAT (Electronically controlled Automatic Transmission) which I know sounds stupid but the 4EAT is a very strong and simple tranny... made in 1993 hasn't changed since. Can hold up to 450 ft-lbs of torque  ;D

Well I'm assuming that the AMC V8 would still be an option so I'd have to say the BIGGEST motor that could be made based off the Indy Cylinder Head IC-401 aluminum block.  Injected and turbo-ed of course.  That would make me smile every time I was in it.  8)

Cummins new smaller 4cylinder engines - which the US will probably never see.

This is so cool, what a great engine to repower an Eagle or an XJ.
Dang it, stupid govt regs keeping diesels and bad-to-the-bone gas I-sixes out of the country. It is a Chinese Cummins, though.

If it were to be a vehicle that would get abused on a regular basis, I honestly would have to say Northstar V8, they are one impressively tough engine, chevy, ford, or chrysler smallblocks can't hold a torch to these things in stock form.  The 4.0L is hard to beat, availability, almost a direct fit, easy to work on, cheap to obtain. If there was a way to build the front axle to handle it, a Buick 455 >:D would be loads of fun in a little SX4, of course the body may need some more structural support too, lol.

I really like the GM 4.2 I6 and for a V8 I like the GM LS engine (4.8, 5.3, 5.7, 6.0). All the LS engines are the same block and accessories. If you have a 5.3 and you want a 5.7 you just change the rotating assembly, and so on. Thats what I love about modular engines. I have actually thought about installing the GM 4.2 I6 in my wife's 88 Jeep YJ.
