    Default 304 vs 345

    i know the 345 is a great engine, is the 304 as strong and durable? i'm looking for another scout and see a lot more 304's out there than the 345. i have a 345 and like it but have no experience with the 304. also what year did they go to disc brakes and the dana 44 up front? thanks, gavin

    Ok, newbie here answering questions, watch out!

    The disc and 44 setup came out in 74. Some 74's had it, some didn't. All 75's had it.

    As far as the 304, I had one in a 72. Loved it, rock solid, would not quit, plenty of low end. I have a 345 now, but have not run it. It is soon to be in a 73 so I can't comment on it yet.

    All IH engines are durable. They sacrificed top end for strength and durability. I have a 304 in my 50 year old fire truck. It weighs 18,000 lbs. I can run nearly 70 mph all day, 24/7, stopping only for gas if I have another driver. It is designed purely for durability. I towed my 67 1200B pickup truck from Arizona to Ohio last May, then to Nebraska in October. Never even got warmer than usual, and on the slight grades, I didn't even have to downshift. I ran 3500-3900 rpm the whole trip except when road conditions required me to slow down.

    The 304 has the same torque curve as a 454 chevy up to 2500 rpms. It weighs 680 lbs fully dressed. Compare that to a small block of the same displacement.

    The 304 is just fine for a scout. I've owned several. It's also fine for a travelall. I once had a 66 travelall with a 304 and pulled a 36 foot travel trailer all over the mountains of Colorado, unhitched, and raced the travelall in a rodeo arena set up like an ice racing course, when 4 wheeling over a 13,000 foot peak, hitched up, and went home. Nary a problem, and the engine was 35 years old at the time with well over 200K on it.

    Yeah, I'd say they were durable.
