I know long stroke ford engines have better low end torque compared to short stroke chevy engines, but it still sucks that a chevy can smoke us at least in stock form, for example the 350 has 255 horsepower compared to the 351 at like 210, but would the low end torque of the 351 help us fords get a better launch than the chevies?
Chevy 400- 2 barrel 185 HP 4 barrel-215 HP (i dont know torque figures)
Ford 400- 140 HP
When ford designed the engine, and it's power curve they designed to tow, and haul loads. Not win races. They also decided that rather than make it FAST we'll make it durable and reliable. How many late 70s early 80s chevies do you see on the road? Not very many. Now how many older fords do you see? I see them here all over and this is a pretty heavy chevy area.
Well the intended purpose of a 4 wheel drive is self explanatory, and I go four wheeling, so when mudbogging I like to get up some momentum, so therefore my "launching" questions.
the chevy engines are over rated from factory. in a 4x4 you want a lot of low end torque something the 350 can't do thats why ford used the 360 engines in the 4x4 trucks until 76.
Do you have any charts showing what RPM the 350, and 351 make peak HP and torque? Either way, Ford knows what they are doing. A truck is a truck. In comparably equipped trucks, i would put a 351 against a 350 any day. You'd think that there would be a big difference, but there isnt.
If you're comparing a 350 and a 351, I don't get where you're coming from. Chevy 350:
4" bore, 3.48" stroke. 351W: 4" bore, 3.5" stroke. Virtually identical. If you drop to 5.0's
then the chevy is the long-stroke motor. Still a 3.48" with a little 3-7/8" bore, compared to the 302's 4" bore and 3" stroke. On the 350/351 comparison, I think both use 1.94/1.5 valves. The only significant difference is the chevy's larger port volume on the heads and shorter intake runner length.
Like these guys were saying, Ford builds their trucks to be trucks not racecars. If I was into any kind of racing, I would build a Chevrolet...they are easier and cheaper to get tons of horsepower out of. But you can bet all of your worldly possesions I will tow that Chevy to the racetrack with a Ford truck. I noticed a lot of people don't understand that high performance motors don't live as long as workhorse motors. So what do you want? High performance...but short lived, get a Chevy. Okay you want something that will work hard and run for a long time buy a Ford. I am 22 yrs old and I could care less about speed. We can't go fast on the roads anyway...there are too many vehicles and cops on the road nowadays. Don't get me wrong I love ALL (Ford, General Motors, Chrysler, AMC...they were all bad a$$) the old muscle cars, but we can't have that kind of stuff anymore...NOW THAT SUCKS!
Armorer- this is kind of interesting- Ford didn't rate them at all, or at least publish the numbers in the brochure. Just listed the engine sizes, tow capacities, etc.
The 350 in my friends 76 malibu classic was only rated at 144 hp. Pretty sure that the ford inline six for that year was close to that.
thats what im talking about. Nothing in the 70's had any power anyways. after 1970, everything went downhill. Well, car wise anyways. I wouldn't think a 351 from 76 had any power either.
Polar, I didn't nessicarily mean in the brochure, just what they are known to be. Listed at places like this http://en.wikipedia.org/wiki/Ford_F-Series And after finding this site I realized that the 300 was only rated at 114hp for 1978, couldn't have been much different in '76.................................Also, if you could PM me and tell me where you found those online sales brochures that would be awesome. I would love to have one for my truck and galaxie.-----Ryan
