pretty bad compared to an overhead valve engine gas or diesel. the en401 continental/Mack was pretty much a site truck engine and way underpowered. good enough for driving around but not much there if you wanna pull any weight with it. then again my grandfather had a single axle b42 and ut use to pull a lowboy with a D8 on it around Syracuse Ny for DW Winkleman. guess it all depends what you wanna do with it.

So help me out. I'm new to this as I moving up from collecting cars. I was looking at this truck online. I'm concerned about the gas engine having too little power/torque. I've read the specs. How bad is it compared to having the thermodyne?

The Gas engine trucks would have much lower gear ratios, the advantage was to use the gas engines much wider power band and wind up the engine and use the power that was available with the higher revs compaired to the diesels. 9.00 to 1 ratio rears were common with the b 42's. and that truck with a tandem would really soak up the horseppower. Most gassers would travel about 50 mph to 55 max. not all but most. now if it had a 707 mack gasser, she would run with the big boys at the time it was built. pass anything but a gas station!

15 gears...no waiting!

the en54o or en464 overhead valve gas engines with a 20 speed 72 series quad box would run with a b61 all day long if not have more ass to it and would start in the winter. the b42's on the other hand were gutless. my grandfather had a whole fleet of them for site trucks and a few single axle tractors. would never start in the winter , said you could hook a chain to em and pop the clutch and heat would be comin out of the heater before the engine would even clear up and run in the winter haha, as for an all around truck just cruisin it would be fine. not for anything else and being a tandem he is right, it will suck what little horsepower is left with the other axle. another thing is the rears, if you ever wanna change them you cant just swap out the hogs heads in the tandems, before 1960 Mack used a wide bolt pattern on the housin and youll be hard pressed to find much faster than 6.00 anythings for them, Matt
