Also depends when

The B61 introduced the 673 Thermodyne with direct injection which replaced the old END672 LaNova injection.

I believe in 1955 the 673 was a 170, but by the end of '60s and into the ''70s it was a 180. Without a turbo, there was no way to ever go beyond that except overfueling.

Cummins always had more cubes and had up to 250 hp unturbo'd so the 711 was introduced at 211 hp. 711 was said to run with a 250 Cummins when you turned the fuel, but it would shoot a foot of flame from the stack then. But the valves ran hot and they were known to drop a lot of valves.

Bore & stroke of the 711 was 5x6 vs. 4.87x6 for the 672/3/5/6 and the E7 was 4.87x6.5 I think.

Try the old macks are us web site. They have all the engines listed horsepower and torque. Engine curves you would might be able to get at the Mack museum.

Hey guys,

I want to know the torque and horsepower for the 673 and 711 diesels as well as the 707 gasser. Turbo or non turbo I would like as much info as possible including torque/horsepower curves.

Thanks

In looking at the Mack cavalcade in Australia it looks like the superliner and trident are the same truck. It looks like they can have the Mack logo in the middle of the grill or the top of the grill. Both have round tanks. The Titan has ugly square tanks but probably higher capacity. Also shown is a granite with a sleeper. They are bringing the Titan over to the US. I wonder if the Trident or Superliner will follow.

I know that the MP 10 is in the family and will be a fine engine, but I think they should offer cummins and cat. This will be a popular truck and broadening the engine base should broaden sales. People buy tucks for different reasons. Some by price, some by name brand, some by dealer, some buy warantee and service and yes many by engine manufacturer. Here in Connecticut mack has lagged due to the big power (Cummins & Cat) in the Petes and Kw's. Mack look at what works and compete. Long live Mack. Stop all this Volvo/New Mack bashing. Macks are still made in America by Americans. They are still made of steal, cast iron, aluminum. Still use lube oil and diesel fuel. Still have dedicated design and engineering people, and they still have one thing no other truck has and never will, the MACK NAME.

The 50's IH cab was used on IH, Diamond-T, Hendrickson,available & FWD. Mack B cabs were very similar to REO Military, IH KB. The LT LJ cab is similar to the H model. A model macks were similar to wc whites. While the F model cab was bigger than the R you can see that it was the similar in style

Cardi out of Rhode Island still runs many aqua blue DM 800's dumps. Not fast on the highway but steady and reliable.

Does anybody know if the CL replacement will come out when the MP10 engine is introduced? Will there be a new mack line up that looks like the Australian line up? Will mack get a COE like the Volvo twin in Australia. I guess we'll have to wait and see.

Ingersoll Rand is not dead they just sold one of there divisions. However there goes another chunk of our industrial base
