Yes, the engineers have figured out how to get more power (or equal power) from smaller engines compared to their big block predecessors. However, when I drive down the road today, I'm sure to see plenty of older model fords and chevys on the road with the 454's and 460's. I'll even see some dodge rams with the older 360's. They'll be hauling big trailers just like they've done from day one. 20 years from now, how many ford EcoBoost trucks will we see that are still holding up? A V6 engine that's made to do the same as a V8 engine? Burn it hotter, pump more air, put higher stress on components. It's not a recipe for long term success.
Burn hotter? higher stress? On a low rpm intercooled turbo motor with better oil and water cooling than an ancient v8 engine revving at 5k RPMs? Oky doky...
See plenty? I dont see anything much older than late 90's trucks pulling rigs up here. There's alot more to worry about than the engine as well. transmissions, diffs, axles, etc. Not to mention frame and suspension corrosion.
are push rod v8's reliable? some are, some arent. Drivetrains? ticking time bombs on a lot of the older ones.
