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 chance.

Not worried either hahaha

mk, sounds like a bad@ss engine. Who's? ATK?
Those numbers seem way off for a naturally aspirated big block though. Not a lot of hp for the torque.
Either way, it'll make red be able to smoke the duallies.
But, reconsider the cost. You're looking at $10k into the engine minimum and more to integrate it and get things like AC and cruise working.
Now add several thousand for a built trans and more for misc items. Upgraded cooling etc.
combine $15 k into a 30 year old pickup that isn't worth much or worth much more with the mods and 6mpg and I'll presume you are just dreaming or talking tongue in cheek.

You'd be better off dropping $25k on an old low mile diesel and wouldn't be out much more if any.

not interested in a "newer" truck and wont own another diesel, it's a bolt in engine designed specifically for these old tow beasts.....and that's all Red is for now. Built by a specific Ford engine builder off a 460.

Better do something with the tranny or you'll be driving in a cloud of ATF.

1996 K3500 Sub and fits/suits me


Still deciding...

Only part of this post that is justifiable, financially and towing ability wise.

Just like the OP, by the time you build a fire breathing 454, super built trans, gear vendors, re-gearing and whatever else is needed (cooling driveshaft mods, etc), you could apply the $5-7k that your Sub is worth, combined with the many $1000s in mods and the future fuel expenses and buy a low mile early/mid 2000s diesel pickup, bone stock, mild canned tune and out pull the Sub past every gas station.

Does sound like a cool hot rod project though and I like hot rods. Just not to be confused with economical and great tow vehicle int he same sentence unless the word "not" is included.

A stock 1000 Allison won't last with those hp and torques numbers. Put a straight drive behind with a good clutch and have fun. YeeeeeHaaaaaaaaaaaw.
Bowtie in the back window optional.

What are you even talking about?
What numbers?

[Cummins12V98]

FISH too funny on the vid, this guy has a shop that works on there trucks. He is trying to get business!

The 6 speed is very rare for a second gen and they are considered the trans to have. FACT is the 5 speed that is common has the 5th gear nut issue but I bet everyone of them out there has had theirs repaired.

Sure some of these things can go wrong on any truck that's 18-28 years old!

Bottom line they hold their value better than the others of the same era for good reason.

Why is that when a stock DM HP numbers are higher than that gas engine and torque numbers are WAY higher?

Similar situation with my Suburban


Looked at that GM 502 crate engine and decided to rebuild the 7.4L

Passing CA smog a must and no one have an acceptable answer on the 502

So my 7.4L is looking to have a 280 cam, roller rockers, 9.x compression, worked head, marched injectors, etc to be a bit under 500 ft/lbs around 2-2.5 KRPMs, etc

Built 4L80E rated 1KHP

Gearvenders with the splitter option, 0.5 OD, which will turn the 4 speed into an 8 speed

5.38 diffs, but having a tough time finding it for the front

That will give a lower 1st and higher OD

Don't know if the Xfrcase will need beefing up

1996 K3500 Sub and fits/suits me

Either LT255/85R16 or LT285/75R16 on current 10" wide alloys. Not going to lift...maybe a torsion bar crank

Still deciding...

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.

I have seen one here and he was trying to sell it with no takers. I hear about a lot of them on this site but its the same folks posting it.

Your truck would make a perfect Fummins!

The bale Dodge out pulls the 04 Duramax dually hauling the same gooseneck trailers. Bellows like a truck engine doing it (6 in a line 1800 rpm)

But the GMC is a tough hard working truck too. 17000 + engine hours and was moving some feed today.

Sold this one to a friends Son. WELL over 400k all stock 2wd 5 speed 98 12V.

Yeah OK...

From the specs:

Recommended fuel: premium

Also do it have oil cooled pistons and an oil cooler for tow mobile duty?
