Most magazines peg 0-60 times around low 4's, so much for slow around town.

Good point about using 3rd and 4th gears.

On the 0-60 though, you don't take off like you were taking off from a stop sign. You take off with as much throttle as you can without breaking traction and then start slamming gears. Not quite the same....

You don't drive downtown in a parade doing drop clutch takeoffs and speed shifting.... (or at least most of us don't)

As I said earlier, that's a phenomenal amount of horsepower from 5 liters. However, the torque is very disappointing and I would imagine that the average horsepower is very low as well. Combining that with a heavy car and a semi-low rearend gear, I think there's a lot more to be desired. That's an engine that would constantly have to be kept at screaming rpms to be competitive.

As an engine builder, this is at the exact extreme of what I would build for a street engine. I tell my customers to try to make the most horsepower in the rpm range that you will be driving. Street cars don't spend any time at 7750 rpm.

I have a 5.0 litre cammer same displacement as coyote and same hp and tq numbers, i drive all day at 7000 rpm on the street, torque is overated unless your towing, especially in a 2200 pd car. Just my 2 cents but what do i know. (3.91 rear gear, don't fear the gear.)

Have you actually had your car weighed? I am curious as 2200# sounds a little light. And has the diff ratio in your rear end been changed becuase the factory does not install 3.91 gears?

Yep, these motors love to rev!

Yes i changed the gears, you have to with no tq, and it weighs 2450. (I usully run a 4.10 rear gear but the btr rear end is small),(4.10 not o.e.m. won't fit)
