In a towrig, this is all I'm interested in; period.

Thanks! You are correct on the horsepower figures, however what I am planning (and what others have done) are first, using an intercooler and second using 127 mm injectors (50-65 mm are stock). I remember reading about people bumping the timing one tooth on the inline models and it resulted in too high of air temperature. It's definitely something to look into though.
As far as the trans, I've already got the RTO-9513. I may or may not do the brownie box. It's defintiely an option. I guess it all depends on if I need the gear or not.
it's a good thing you're not building my tow rig then...CDA 455 said:
horsepower is a measure of work, torque only gets the wheels moving. if you have crappy horsepower, even if a million ft-lbs of torque, you'll be getting nowhere fast.

really seems like a lot of extra work swapping to this other engine, how about just tossing in a duramax, etc and a tune along with intake and exhaust and making 1000ft/lb of torque ?
Actually, horsepower is torque per some unit of time. They're directly related. Infact, if you look at any dyno sheet of any engine from a lawnmower to a formula one V10, horsepower and torque are exatly the same number at 5252 rpm. You can't have one without the other.colbystephens said:
Okay, now I'm going to stop spamming my build thread with theory talk.
Oh wow, this is a lot to digest.
So you basically want to make a a medium duty truck out of a 1 ton pickup, correct?
Well, I won't knock you for going with a 4-71 at all, because that is what you want. But, for what the 4-71 is capable of, or a lack of it, I'd be using a different engine myself.
I'll have to sing the same song with the trans, I don't think I want to row through that many gears, have that huge of a trans, and all of it's weight. But, if you do use it remember to not pre-select.
The axle setup sounds pretty good, go with the 19.5" alcoas that are on the F450-550 trucks!

true. i was simply making a point.ARAMP1 said:Actually, horsepower is torque per some unit of time. They're directly related.

one horsepower is 550 ft-lbs per second.

I wondered about the injectors. You know you could add propane to this before the turbo under high load conditions for a hp boost.
Whats it's going to take to find the missing engine parts? Well besides cubic money

Yeah, I've thought about water, propane, or nitrous. As far as scrounging for all the parts and pieces, it's just going to take time. A whole lot of me looking. I've got this idea in my head of how I want to put the engine together. For instance, I don't want to use the standard truck rods and pistons, I want to use the cross type connecting rods. I still don't know if I'm going to use a bypass blower or the standard blower and just duct the turbo into the airbox through one of the engine ports. I figure I can put the engine and transmission together for around $5k.

Any updates with pics?
hopefully!
Unfortunately, I'm still in the process of building the engine. I just got back from a few months of vacation in the desert and have been pretty busy since then.
subscribed, sounds like a very interesting build
WOW! It's Been Two Years Since I Started This!!!
Well, after two years, which includes two deployments to the middle east and multiple TDYs/exercises, I'm ready to update this a bit.
As of right now, my engine is built. Just to recap, I started with an aluminum Detroit 4-71 block.
I've been collecting a bunch of parts. From the big stuff like the crank, rods, head, turbo, etc. To smaller stuff like the exhaust flange, oil cooler, etc.
New crankshaft (found it on e-bay for $100)
New four valve cylinder head. Jake brakes will be added.
Pistons are the heavier duty two piece with the domes ceramic coated and the skirts teflon coated.
Here's a picture of the turbo. Think it's big enough?
Anyway, here's a picture of the engine fully assembled.
Painted the engine Detroit Alpine Green and added a nice shiney polished aluminum valve cover.
Jake Brakes are in!!! My neighbors are going to HATE me!
Polished valve cover doesn't fit with the Jakes.Going to have to make a spacer.
Well, I cut the top off of another cast aluminum valve cover and TIGed the bottom to the shiney one. That should do. And, it'll stick up a bit over the water manifold and should be the first thing you see when you pop the hood.
Jet hot coated exhaust manifold and turbo housing (exhaust side).
I'm planning for a five inch downpipe and then it'll open up to seven inches under the cab and to the back. I'm thinking about doing the stack straight up through the hood, but my wife is against it. She says (and I quote) "The truck looks redneck enough already without the stack through the hood".
I'm still thinking about doing it anyway.
Front shot of the turbo.
Here's a shot of some intake detail.
Well, that's where I stand with everything. The big block is coming out next week and I'll be mocking up the motor mounts. There's a lot of little stuff to do like figure out the clutch linkage, throttle linkage, coolant lines, accessories, intercooler, etc. I've got three weeks of use or lose leave on the books starting monday, but it might get cut short so we'll see what I get done.

Stupid question... What is a Jake Brake?
