Originally posted by Robin We don't have many 'big' pickups in SA. You'll see an occasional Dodge Ram or F250, but they are mostly special imports. So the market is dominated by the diesel double-cabs, and the engines are getting smaller! The latest Ford 2 liter biturbo, is only outperformed by the VW V6 diesel, and has great fuel economy. Jeremy Clarkson predicted it a few years ago, but I think it's now reality... big engines are a thing of the past!
You and Jeremy are probably right.
I've always liked a big, displacement naturally aspirated engine.
I remember the days when a Chevy full size pickup would have a 350 cubic inch (5.7 liter) V8 as the basic engine and a 454 cubic inch or 502 cubic inch V8 (8.1 liter) as the optional engine.
In the mid '70's I worked as a salesman /truck driver for a company, while attending university. The company truck I used for my routes was a Ford Econoline cab and chassis, with dual rear wheels and an insulated 16 foot, refrigerated box mounted on the truck frame. A wonderful truck to drive.
It had a gas 460 cubic inch (7.5 liter) Ford V8 ( 4 barrel carburettor) with a heavy duty C6 automatic transmission. It was very capable and I found with the very large V8, even with a full GVW of around 12,000 pounds plus....that big V8 had what seemed to be remarkable passing power on the highway. The 460 engine seemed to be loafing at all times.
Before that truck, I used an Econoline cab and chassis with a smaller 12 foot box and a 302 cubic inch Ford V8. The power difference was significant (much less power/torque with the 302) and as far as gas mileage went...with each truck carrying a full load...if I recall there wasn't much difference on MPG..
The fact that both trucks got similar MPG, even given that the larger E350 had a greater GVW...was due, IMO...to the fact that the 302 had to work hard (was at higher rpm) to move a heavy load, where in comparison the 460 with it's much greater power/ torque...never really seemed to be working anywhere near maximum rpm ..
Turbos on smaller engines are fine, but the idea of a large displacement, non turbo engine has always had a strong appeal for me.
Years ago I recall driving a '69 Chevy Nova with a 396 cubic inch V8...375 hp..4 speed Muncie and around a 4.10 axle ratio. That thing really moved, sounded great with low back pressure mufflers. It was always an experience driving it, even if it was just slow trip to the grocery store.
Memories ....
