FWIW, my E body weighed 3750+ with me in it the last time it was on the track scale. I haven't been running anything but stock-stroke pump-gas 440s, but the last two engine combinations were good for low 11s and mid 10s respectively. The 11-sec engine made around 540 HP and the 10-sec one cranked about 610 HP the way I ran it on the track, altough there was another 10-15 HP on the dyno while testing some parts not run as installed.

Switching to 3.55s and a 3K converter would have made it easier to drive at highway speeds, but would also have slowed the ET by around 1/2 sec. That's where those stroker bulds are supposed to help by making big torque that doesn't need the extra gear & coverter... but the combination still needs to be "right".
