Ken, I am impressed with the work that you have done.  Some folks seem to think that suffing one of these monsters in a bus is about the same effort as stuffing a Chevy in an old Ford.  Those of us who have done this know the huge effort involved and your documentation proves that . 

Now, we need a You Tube video of the monster pulling out of the shop on its own power ;D ;D

what kind of lathe is that?  It looks a lot like mine - Southbend 16" by 60" tool room lathe.

Nice job, what a lot of work!

WOW! What a nice warehouse and machine shop you have-I'm severely envious. 

If I could make a couple of suggestions-did you see if you could remove the valve cover with the engine in place? Usually buses have to go to the 2 piece aluminum valve covers.
Second-no matter how many miles on the donor truck, you should replace with new the X and Y shifter motors on top of the transmission.  They have a recommended replacement of every 300,000 miles no matter how well they are working.  Probably easier to do now then later on the side of the road. 
Otherwise-you're workmanship is top notch.  You could easily do this professionally.  Good Luck, TomC

Bk, as you can see I haven't work on the bus much, I've mostly just watched reruns of Oprah. I'm just heart broken since her show went off.

Jim, I'm sure it's going to eventually leave under it's own power. I hope it comes back under it's own power.

Brian, it's an old South bend, 16" swing the bed length is unusually long, I don't remember the length right now.

Tom, I do have a two piece valve cover on it now and at least the top will come off in the bus, I haven't tried the second piece yet. I have a new set of XY shifters in stock. Thanks for your complements.

Nice, nice shop!  What is the story on the Silverside in the background?  Looks like a repower going on or something?  Great job.

Ken  If you get this finished by this weekend.  Then we could put the 50 in HUGGY next week end and then head to Arcadia for new year.

Looking good and as always good to hear from you.

This looks strangely familiar!!!. I figured about two months to put a 60 in an eagle. I was a few days from six months before I ever heard it run!!! But it was worth the work!!

Boomer, that is a 1947 Silversides. I was hired to installed a Series 50 and V730 with the reversing gear and I have most of the hard part completed, but I think my customer has changed his mind.

Uncle Ned, since I let my mouth overload my @$# so many times in past 6 months I'm not afraid to say, I'll finish mine this weekend. You go ahead a get a Series 50 and transmission on a trailer behind Huggy, I'll ride with you to Arcadia and install it on the way and oh yeah it won't cost anything either. I'm just that good.
So now you are going ask, why would I need to ride with you if yours is going to be finished this weekend? Just maybe, I'm a liar and hard headed. And as always, it good to hear from you, just keep ribbing me.

Eric, I've been doing this kind of stuff for 30 years and I still can't estimate a job like this. It always takes longer and cost more than I think it should.

I checked out the S50/730 conversion into a Silverside that Bernie in PA did.  I have to say, that is probably the single most difficult conversion into a bus that I have yet to see.  Proof positive that you can do anything with time and money, eh?  I'll stick with putting the 6L71TA DDEC in my Silverside.  330 hp, nearly the same as the S50 and a whole lot easier and cheaper.  Again, nice work Ken.

I drove many hours to look that bus. I took many pictures and made many measurements. At this point I don't think it's a much more difficult swap than my Prevost repower. It just looks worse. Take a look at the pictures and I'll stop there.

Boomer-yes the 6-71TA DDEC will be a much easier conversion then the Series 50 and the power is about the same, BUT-there will be about a 2 mpg difference between the engines.  If you're going to drive alot of miles (like Sean at 20,000 miles per year), maybe the hassle of the Series 50 would be worth it.  Plus-anyone can work on the Series 50 compared to an ever reducing number of mechanics that know the nuances of working on the 2 stroke Detroits.
Other engines that have been used with the reverser gear on the V730 is the Cummins ISC/ISL (same block) and the Cummins M11/ISM.  The ISL in its' current form is available up to 425hp and 1250lb/ft torque-much more then the 6-71TA DDEC would put out AND get better fuel mileage.  Good Luck, TomC

Yes I know Tom, but there is a monumental labor cost to completely rebuild the back of the Silverside as well as changing diffs, suspension, cooling/CAC system, on and on, etc. etc.  I wouldn't live long enough to pay this back in the small fuel savings, even if I drove 50,000 miles a year.  Besides, I want some semblance of originality to the rig. The worn out 160 hp engine in it now gets 8.8 and I fully expect around 10 with the new engine. Check out Bernhard's website to get an idea of just how extensive that conversion was.  I would wager that the cost was in the mid 5 figure range.  Really nice job tho.  Hope the owner is enjoying it.
