Way freaking taller LOL but, I bet it has a good chance to fit under a truck hood. We needed a Boss 9 scoop on a 67 Mustang, but that's a whole different animal
As far as low end, we didn't see a low end power issue, they are long runners which help torque, but as Jay said, you need a good pump shot if you foot tries to go deep into it in a hurry. A pair of blue pump cams would likely do it on a pair of 600s, worst case, go up a size on the shooter to get it there quicker. If you have a good timing curve and not overcammed, I doubt it would be that much trouble.
