Ok maybe 300hp is a little bit of a reach with stock injectors. But 250-275hp is definately doable. This would be on a VE pumped engine???

Keep in mind, rule of thumb for torque curve on mechanical cummins is torque to hp is 2.5 to 1. Vp engines are closer to 2.0 to 1. I'm not sure how HPCR engines rank. But at 250hp you're looking at over 600ftlbs. That's on stock gear.

Luke what are the Vp and HPCR engines?
And stock gear, you mean stock long block, or actual gears...forgive me for I am the king of retards when it comes to Diesels:doah:
 
Oh sorry yep. That's on a VE engine. And by stock gear I'm just generalizing "gear" as in, injectors pump turbo tranny... Etc.

VP44 engines are the first 24valve heads. '98.5-2002 the pump is a rotary electromechanical control injection pump. Mechanical injectors. HPCR - High pressure common rail injection. CP3 high pressure fuel pump. Electronic injectors. No injection pump. '03-on.

You can absolutely get 500-600ftlbs torque out of a VE engine with pump mods. Now getting it to the ground is where you want a lockup converter or clutch. Non lockup is an absolute waste of efficiency and therefore total waste of time to swap to anything nonlockup imo.

OK Dave here is my .02

After towing down to the bash and having a stock Cummings and being followed by a 454. I would build a nice built dependable over drive equipped big block Chevy before I would do the swap in a tow only rig. Yeah the mileage is cool, but for what once or twice a year not worth it. I could build a really nice 500 hp BBC for the price of the swap.

That being said I am doing my swap. I plan on driving mine on more of a daily basics and it gets 20mpg cruzing around and no gas will ever get near that. I'm going to mod it and I already got the 5 speed and the 205 so its going to be a rockin set up but I am into it some coin.

The daily driving part is the kicker if you not, its not worth it
 
Truth there. If you don't daily type drive it, you'll never recoup the swap. But that said everything I own is diesel, Cept my BBC z28.

In my experience with engine swaps is figure your price for the swap and add another 25% for the things that didn't work quite they way you figured they would.

That being said, i've never done the cummins swap. Lots of guys have which might help you nail down the costs a little tighter.
 
Not to get too far off topic, But Kert,
How is your BB CC dually on long hauls?

I used Bart to tow to Moab, 900 miles total, very comfy, very comfy

I would say pretty awesome if ya ask me

Oops were you asking about Kerts rig or daves?
 
Actually anyone with a big block.

We.use my 86 k30 CC with a 454 for about 400 mile round trips all in one day. And it loves the gas. If I remember right we use about 50 gallons of fuel. Power is decent, brakes are ok,

I was just curious what you guys thinkin about them for the real long hauls

Kerts has got a 500 caddy :D
 
There's a couple of us with the VE pumps. Not bad and cheap to mod. They'll support up to 500hp with some coin. Like Demon said, fuel pin ($100), spring ($20) and and hour of your time and you'll be where you want to be TQ wise. That is unless your pump starts leaking, like what I'm dealing with now. Then you'll have about another $800 into it.

Check out Rompinstompinmudmonkey's thread. He tows very regularly and does heavy stuff too. He may be able to help you with A/C compressor brackets too. :whistle: I think there's enough of us on here with the swap we could get you through it easily.
 
Hey guys, thanks for all the input...as much as I want to keep this project under control cost wise, its not something I'm too good at once I get started....I mean what might start out as a snowball, might end up being an avalanche....with that said, I'm still thinking I need to check out the 454 more and see what it will take to get it reasonable as far as oil consumption goes, and maybe tweak it a bit for a little more power and mileage(:haha:) if its not a complete engine job. I could just swap engines with the Maiden...550tq that it has would be nice to pull with.

I need to school myself more on the Cummins swap, and if I feel I want to go that route, I'll look for a deal on one, and try to determine a trans route to take.
It doesn't sound like the piece in the C/L add is a big deal. I was thinking it was one of those deals that would be too good to pass up.
 
My opinion is a bit biased because of location but.

There's a reason those of us in the mountains have big turbo diesels with power adders. Honestly we need them but that's because any NA truck is going to suffer big time at 10,000+ feet.

I think going the route of a cummins will be a relatively big deal but it has been done a lot, there are kit's for cross members mounts etc out there so it's not that hard.

However, can you build a good 454+CI engine for the same amount of money as the swap, I bet you can. It's going to like the gas but then again I don't see a diesel getting more than 12 to 14 MPG towing, most likely even less. Yes even the diesel sipping cummins will drop down to that range when loaded.
So I see it as a wash really. For a trip or two west each year or two you can use the routes with the fewest mountain passes and do just fine.
 
this year going to/from BB we went up through Laramie, which was I think close to 7600, and heading east on 80, I was down to 1st gear for most of that climb, also coming out of Rifle headed north. So I know what your talking about. my 6.0 did really good other than that I thought.
Now I may only get that high once or twice in the next 5 years, so other than that I'm sure the BBC will do fine towing my 10-12K...
 
I know, its tempting as hell to jump at one, but I really need to keep researching this to see if its where I want to end up.
 
It's always a case of lead with your head or lead with the heart. I pulled the 7.4l vortec out of my '98 crewcab for the cummins, cause I could no longer deal with filling up every 3rd day. Best thing I ever did to it.

sometimes my head don't work so good when I see something I WANT...
 
Luke are all of the previous mentioned 91-98 engines turbo'd?
