Found my replacement engine!

[mountainkowboy]

Introducing the new 502" EFI crate combo. 581 TQ @ 3,200 436.5 HP @ 4,600.

This baby is READY TO WORK !!!

We've been wrestling around with the idea of replacing Red with something younger and I just don't see the need. I can put that money into her and get basically a brand new truck that will out pull any new gasser.....lol.

Not to mention a twisted driveline or rear end scattered all over the road.

If that's the case, my Ram is screwed. The Cummins has over 600 lb ft of torque AND it has a 6.29:1 first gear. No rear end would have a chcance.

Lots of people do that conversion, "FUMMINS"

I've yet to see one in the wild. As a matter of fact it's been many...many...years since I've seen a 12v.

Maybe Texans aren’t as resourceful...lol.
Plenty of guys re-purposing otherwise worthless Fords with 12Vs around here.

And this is coming from the truck capital!

YEP, thirsty but FUN!!!

So I am figuring it is more thirsty than my 8.1 but a fair bit more power?

Bolt up to my Allison?

Oh, and mountainkowboy seems like a smart enough dude to realize this.
Given he hasn’t replied back, I’m sure he was talking tongue in cheek and is enjoying the ensuing discussion!

[Grit_dog]

Why do y’all assume he’s using a GM Crate motor?

And the “cheaper than a new truck” argument is the dumbest argument ever, in this scenario. It’s also cheaper than a new class A or a condo in Maui or the hope diamond, but the comparison between a 30 year old pickup and a new pickup, even if the old one is hot rodded up is still like comparing apples and toothpaste.
Fun project, yes.
Practical tow rig? No
Not even close to practical.
Compare it to similarly priced options and decide if it’s the best choice, not some pie in the Sky $60k NEW truck.

Besides, it’s 2020, not 1990 anymore. Big pulling power, if that’s what you want, doesn’t come from gas engines. You have to pull up to the green pump handles if you want real pulling power.

Now, a 12V swap makes more sense. Costs less, more torque and way better mileage.
Plenty of plug n play (almost) kits for that. As long as you’re a good wrench.

Actually, a good friend of mine did just that and finished it about a year ago. A 1978 F250 SuperCab with a 12V Cummins from a mid-90s Dodge. Wish I could find some pictures of it, it's a beautiful truck.

Hope its better than the last GM 572 crate motor I bought. Put it in a 56 chevy and first time I started it it blew both head gaskets. Not torqued from factory and they would not even send me a gasket set.
My problem they said.

A GM crate motor in a 1990 Ford?
