I don't have any dyno's on hand but I want to say the older 4.7 put out better torque to the wheel than the new one's in stock form, just from seeing the graphs you linked to.
Maybe with a cam...? Definitely not stock.
Old 4.7L 295 lb ft peak
New 4.7L 330 lb ft peak
Same exact drivetrain(transmission and rear axle) so no way there was a difference to the wheel. Unless it was manual trans.
Not to knock the old 4.7L, it's a good truck engine, but the new 4.7L is significantly improved upon. My dad has a single cab 2005 4.7L "work truck" and it runs fine but it's pretty slow. I have my 2010 4.7L quad cab with much larger and heavier wheels/tires and it is ....let's say....quick. I wouldn't say it's fast, but it's fun and "peppy".
I wish someone would make cams for the new 4.7L, and long tubes. You'd see some 400+ hp 4.7L's if it ever happened. That's a lot of power from a 287 NA.
Anyway, this is about the v6 lol. So do you have any other plans or just going to be satisfied with it as is?
