How so? stock 12v are 160+ hp and 400+ tq stock, and for 9K, you could get triple that.

Cummins R2.8 in K5?

$9k gets you a brand new R2.8 crate engine. While it sounds good on paper, you can buy a lot of engine for $9k.
My question was based on the assumption that a used ISB engine is a good bit cheaper.
Sorry, I’m talking about the 4 cylinder 3.9 ISB I have in breadvans. Stock they are a lot more power than a 12 valve. They are 16 valve common rail, basically a 24 valve out of a dodge pickup but 4 cylinder, and I sell them with Allison 1000 trans for $4000
I sell complete running vans for $4500-5000 could probably sell a drivetrain for $4000. That is the common rail 4 cylinder, an allison 1000 and a stand alone controller
If you're selling it with the computers that's a damn good price!
I should’ve been more clear what motor I was talking about, my bad haha
Drove this down the interstate to the swap meet fully loaded at 70-75, got around 10mpg. It had a ISB 3.9 did good burnouts too.
That’s the term for cummins model engine.
“Interact system” b model engine. They have isb, isc, isx.....ect.
I’m not even 100% sure ISB is the correct one for the 3.9 common rail? That’s all I’ve ever seen them called rhough
I’ve had this opinion (from my arm chair) after watching videos of Fred Williams TJ with that swap.
I think they went to the interact system around 98

I'm in the shop
The ISB has computer controlled injection pump, injectors and timming, I think the fuel pressure is 32000 psi and injectors cost $350 -$650 each. Since the cam doesn't have a lobe for a fuel supply pump they require electric pump. They run smooth and have more than the power but cost more. I'm not sure if there is power programs for the 4 cylinder ISB ? The advantage of the older mechanical 4bt and 6BT (12 valve) is it doesn't need a battery to run so if the zombies are chasing you would have a better chance of staying ahead of them and injectors could be less than $200 each. I have a common rail (ISB) in a 03 dodge and it runs awesome! 
You can get 24 valve injectors for like $190 plus core, I don’t see the 4 cylinder ones costing more? Also they are very smooth compared to a 4bt. I don’t believe they are more expensive. Maybe to fix, but people pay way more for a good p-pump 4bt. Mostly because no one wants the wiring. But it’s all standalone and I have a complete gauge panel for them
I'd like to hear/see more of this 28-29 Model A.
too cheap

The Cummins R2.8 has been available for over a decade outside of the US market, installed in the smaller delivery box/flatbed trucks and used in stationary/offroad applications. Common in Asia. The 2.8 and the 3.3 are the modern replacements for the older 4bt's 3.3 and 3.9. Talking about the 1.5 ton and lighter classes of medium duty trucks.
Stock form they make more torque than the 6.2 diesel and the 350 gasser. Cummins offers programming for it up into the low 400ft/lbs of torque. They have tested it at over 500ft/lbs but won't offer it at those levels.

Didn't Fred Williams have this 2.8 cummins in his rig on UA last year? He had plenty of wheeling power on a well built (not light) Heep. And from what he said, he was sipping fuel compared to everyone else. Yes, there are a lot of crate motors out there that make a lot more power for the same $9k. But, none will get the same mileage.
And if you're the type that keeps vehicles for a while, no gas motor and especially any V- motor, will ever last as long as one of these inline diesels.

See, I am from this club, don't need 1000hp to get the job done.
I think if I needed an engine and had the $$$ I would put this in a k5.
I would make sure I matched the gearing to the torque curve and I would have a very economical everlasting truck.
My big rig is 455hp/1500lbs tq pulls 80k lbs up hills no problem and can go million miles and more getting an average 8mpg.
I don't need thousands of hp
Yep, I mentioned it earlier in the thread. I personally was not impressed but I could see it attractive to the overland guys looking for mpg.
