I still haven't gotten to drive a V8 RWD, ever. Well, other than a truck, and that's nowhere close.
The V8 FWD was an absolutely shitty car with a magnificent LS4 derived short block transverse-mount linked to a four (or maybe five) speed slushbox. The car got somewhere around 270 FWHP, which, although not that imposing - considering a G37 can get the same figure (albeit AWHP or RWHP), along with several other extremely modern V6's - came with a very wide and flat torque curve of a similar figure, and the power response on tap was huge.
It was a little... sluggish? Reluctant? It's not like most 6's and 4's that rev up fast, downshift at the drop of a hat, etc. It revs up slowly, and it rarely downshifts - it obviously has more rotating mass, which would affect it, but perhaps it was significantly overstroked (very likely), which I know improves low RPM performance at the cost of peak RPM operation. But if peak RPM operation has been curbed, then it may also indicate the motor is vulnerable to high impulse?
