A lot of talk about engine swaps and rebuilding the 2 strokes I spent a little time talking to friends at DD dealers across the US last week and they were all about the same for a rebuild to put the 71 and 92 series engine N/A back to OEM specs for a out of frame rebuild here it is read it and weep

United Engine in OK   $2800 + per cylinder
WW WIlliams in AZ    $3000  +
Stewart and Stevenson in Tx  $3000 to $3500 +
Pacific Power  in Or $3500 +
Valley Power a whopping  $4800 +

the price on a TA engine rebuild goes up

All these prices are without needing major components like the crank ( 4900.00) with rebuilt heads, 3000.00 each for new no line boring or new main caps these old girls are getting expensive to rebuild when I started you could figure a $ 100.00 a cylinder   

A little  info you guys

Wow! Some days a fellow doesn´t earn that kind of money!

I love our Mexican labor costs. I spent a total of 45,000 pesos parts and labor (aprox. $3,330 U. S.) for completely rebuilding both heads, all new sleeves and pistons, gasket sets, etc. And I thought that was a lot of money! Most parts for the *53, *71 and *92 series Detroits are still being made and sold down here.

The brand new radiator core with installation was less than $700 U. S.

I have heard the price of 40 to 50 k to but in a four stroke and automatic. If you figure 1/2 the price is labor and you can do the work yourself it makes sense to put in a four stroke. You can get a little better fuel mileage and they are easier to cool. My labor when I am off the clock is worth nothing, or if you figure it takes you two months to change it out that is about 25 an hour based on a 50 hour week. The price is for a used motor and trans so you will have to guess how long that set will last before you have to pour more money in a rebuild of that set up

Wayne we both know a guy that spent 55 grand on 8v92 2 years later the turbo turn loose and he spent another 50 grand,one thing about the 4 strokes the electronics don't lie they are easy to track with the little hand held gizmo and if they ever been in a dealers shop it will be on record heck the 2 strokes have been around before the word record was in the dictionary Roll Eyes

Yes it is a crap shoot. I was thinking about my labor calculations and I made a mistake. When you get done with the conversion to a four stroke you will not get back the 40 or 50 k. You will be lucky to get back 1/2 of it if you were to sell the bus. So that puts the labor back to 0 our less. Oh well think of all the fun you had.

I guess there is something good to say about only having the 6 V 71 and no Turbo!...... Grin

Driving a old 6-71 is fine till you set down in a 6v92 turbo with big injectors and auto.

lots of smoke and heat but people get out of your way and don't follow to close.

Just have to carry along a lot of carolina mountain spring water to stay cool.

A out of frame rebuilding to OEM specs by the time you remove and reinstall back in the vehicle it can reach a 100 hrs plus easy 
 
You can spend 2 or 3 days fitting liners to the block on 71 series since you cannot buy different sizes any more like the 1,2,3 or 4 sizes now it's one size fits all you make them work anything over 4 then it is big bucks to bore the block something I am not a fan of.

 Most shops don't care if takes a hammer and block of wood to drive one in that's ok with them the engine will last past the warranty period 99% of the time

Just makes me reconsider the value of this old girl, (not my DW!). I will definitely keep the towing on my insurance policy because if she ever craps out, she's being towed to her final resting place and probably mine too. That's straight from the old girl's mouth (DW).

Yea but a lot of the time you wouldn't need to do a complete rebuild to OEM specs. Just fix what's broke and keep on busing... Or look for a used take out that runs good to replace your broke one. You can do that for way less than rebuilding to new specs.

Back in the mid 80's I worked in an engine machine shop.  I would grind the caps and rod beams on a small block chevy, (resize big and small end) send them to a hone to be finished.  SBC rods cost a couple of bucks each.  Rods for a 4308 Cat took the same amount of work, same machine, and cost 10 times as much.  Very disappointing to see 4k per hole on a mechanical engine.  Bend over, you drive a big rig, you WILL afford it!

I am with JC but shops don't want to do the repairs or fixes any longer just major rebuilds,there does come a time in life when 1 does need a complete rebuild they will only take a inframe so many times fwiw, there is a old saying the 2 strokes never die naturally they are murdered  

I have a 8v92 here now that was murdered not by a owner but a shop (big shop) that had no idea what they were doing Roll Eyes The shop installed 3 sets of new cam follower rollers on 3 cylinders they failed taking out the cams on both sides all because the shop did not know you cook and treat the rollers in Cindol for 30 minutes and now he is out of warranty because the bus just set for months sad he paid 27,000 bucks for the overhaul
