B61TENDT711

I see, i guess in the time frame it was used it was a very neat trick. . .

But yea i don't see any body dropping a newer body on an older these days, everybody seems to run what they got as it was.

Mike

I got told many horror stories about if you lugged a thermodyne it blew head gaskets and if you hit double neutral and you couldn't get one or the other back in gear at the right time you would have to come to a complete stop and start over.

Mike

eo i have noticed those a few guy tweaked around with some floats and wide rims with custom off set's to sorta correct the issue but but all in all you can still tell. . .

Mike

Really ? . . .

The Reo gas engine in my Studebaker 2.5ton 6x6 runs great pulls like no other Gas engined big truck had ever seen, most of the gas powered trucks i've owned in the past where high revving slow moving Gutless dog's, and this beast totally changed my thinking on Gas engines and large trucks.

I'm used to driving F700 Ford's with 351 n 361 V8's or C60 n C70 GM's with 350 n 427 V8's . . .

I found the only Gasser's that performed well where the GMC Big Block V6's, the IHC 345's n 392's and this Amry surplus Studebaker with the REO-331 I6.

I haven't owned a Mack Gasser but i'm sure after running Mack turbo diesel's i wouldn't be impressed by them. . .

Mike

Really ?

I figured with the Gasser you could just pick your range and bang gears 1-2-3-4-5. . .

Thats how i was taught to drive the IHC Gas engined truck's, pick your range and shift. . .

at least missed shifts on the gas engine don't = crank case full of coolant

Mike

I bet them Gas engined Mack's are nicer to drive no splitting. . .just clutch n shift maybe even shift no clutch

Splitting the Thermodyne so you didn't split the Thermodyne stick your arms threw the steering wheel and start grabbing gear, hoping you never hit neutral on both sticks at the same

Mike

My Reo-331 isn't a flat head. . .it just seems like an awful lot of truck builders used the Reo Gas engines. . .

Mike

a truck ain't a truck till its got some dent's scratches and some rust. . .

Mike

I think today it would be more fitting to drop a B-model body onto an R-model chassie n power plant. . .

Vintage B look Modern R power and road speed. . .

Mike

The KT-Cummins diesel had 3 power settings.

450hp 525hp 600hp

1150cid I6.

Mike

Sure loved the word dyne. . .Thermodyne, Maxidyne, Econodyne and Magnadyne. . .

Did i forget any ?

Mike

Cool stuff

Mike

Wowzers. . . That is one big bulldog

Mike

The biggest Mack truck's i can Find or the Military M123/M125 10ton 6x6's and the CL350 Logging truck

Was there any other Large Mack's produced ?

Mike

IHC n FL got the market flooded with medium duty n heavy duty commercial trucks.

It don't look good for Sterling or Western Star.

But you gotta remember we now have more trucks then jobs and folks are now starting to go back to the old style of thinking were they ran a truck till its worn out not till the body style changes...

Mike

Yet again those crazy Canuck's are not waiting for Mack to put out a sleeper

That truck looks ready for Ice Road trucking 3 rear axles all full sized tires. . .

Mike

any chance of the EN331 being a Reo engine ?

My 1953 studebacker M275 Has a Reo-331 I-6 gas and the intake/exhaust manifold assembly says on it "golden comet power"

Mike

Like I said I'm not betting the farm on it truly making 315hp that is just what the shop technician told me.

I got 6.38 gears and my rev's threw the gears float between 2200rpm n 1600rpm.

Rap it up to 2100-2200rpm shift it drops back to 1550-1650rpm.

I'm never hard on the throttle tho ease on it then ease off it.

With them 6.38s n 12.00-24 tires it rolls 65mph@2000rpm.

Mike

Yea they do have a uniquely unique sound them 711 turbos do...

My 711 diesel has a turbo charger on it the guy I bought it from had it added.

This why in my sig lines I always list is as a END+T 711 as the T was added after the fact.

When it was rebuilt 12years ago they dynod it at 315hp at the fly wheel.

Which I thought was a big jump from 211hp but then again its a turbo charged non turbo diesel so I guess cranking up the fuel n adding some boost I guess its possible.

All I know is the beast tow 100K n not bat n eye.

Mike

I know the site I registered my 59' B61T there back in 01...

I never thought about looking for Mack info there...

Mike

EN707 ?!?!? my 711 is 707CID so i basically have a High compression gas engine ? . . . that some one creatively Turbo charged

Mike

I did a few dozen google n yahoo and even ask searches i can not find anything dealing with or related to Mack Gas engines. . .

I was chatting with a friend and even he don't even remember seeing a mack powered by nothing other then a Diesel engine. ..

Was there no such things as a Mack Gasser ?

Mike

I found it :

"B61T 24562 '59

Mike Droster

Madison wisconsin"

I knew i put my truck on there years ago

Mike

Mike

I getcha now
