What's the appeal of an aluminum engine block?

Can I disguise my voice?

EDITED....

I was assuming Lippy was talking in my Hillbilly vernacular....which would mean that 4% isn't *anything*.

Power to weight ratios are laughable at the level of a high horsepower Cobra. With 600 hp, who here can tell if they are carrying a passenger at WOT?

Where the difference may lie is the weight distribution. I had both a stroked 351W and a 428 FE in my Cobra and, IMO, the difference wasn't noticeable. However, to be fair, I didn't get much seat time before I got bored and sold it....

If the weight difference was out there hanging off the oil cooler, I could see some value in lightening the load. However, with the engine's weight so far behind the front axle centerline, I just can't see the advantage unless you were on a road course. And even then, to really find the ragged edge of each setup, you'd probably need more than a conventional wet sump setup....
