The engine was a Mack EY, 6-cylinder gasoline with a displacement of 707 cu in 11.6 L generating 159 hp 119 kW at 2100 rpm and 534 lbfft 724 Nm at 800 rpm. 2 The transmission had 5 gears forward and one reverse.

The Mack 707 is a 707 cubic inch 11.6 liter gasoline fueled motor developed and produced by Mack Trucks for use in their many models of truck, from semis to firetrucks. This file is modeled specifically after the quotBquot variant found in Mack L model firetrucks. This engine was brought to ES with help from Archangel Motor's Crate Engine Packs

The B-series was the first Mack truck produced with a diesel engine, introducing the Mack-produced Thermodyne inline-6 in 1953. 1 The B Model offered 10 different gasoline engines, from a 291 cu in 4.8 L with 107 hp 80 kW in the B20 to a 707 cu in 11.6 L with 232 hp 173 kW in the B70. A wide range of diesels were also offered.

No,the 707 was never available in the DM800.The 707 gas engine dates back to the 40's and was last used in firetrucks into the later '60's.I believe there was even a early version of the 707 used in the AP of the late '20's. The DM replaced the B80 series trucks in 1966.

Was the block the same for both engines. The 707 must have been a beast of a gasser. Its life was short lived as it came on the scene to late as diesels such as the 673 were coming on line at the time. I believe IH's biggest gasser was the 501.

Some information I have found, people confuse it with the Mack 707 and others say its just a bigger GMC 503. But, I finally found something, in writing to deny those claims, from a GM quottransmissionquot service manual for 1937-41 Yellow Coach, which gives 2 engine options, either a 707 or a 529 cubic inch.

The 707 engine is not GMC,Mack had a 707 OHV inline 6 gas engine in the 50's.Extremely heavy engine.I think the largest GMC built inline is a 502. Mopar never made a 413 inline,but the 413 B block V-8 were used in their own trucks and some Macks Truckedup, Aug 3, 2008.

There was a category that required a 700 cu in engine which made the 707 Mack a popular engine for fire apparatus. The 5quot bore 6quot stroke Mack was a very durable work horse, but I don't think it had anything to do with GMC.
