Sure, Stuart, but think of what happens if I do similar things to this engine
The 1970 Eldorado 500 put out 400hp out of the factory. Compression was dropped the next year to allow the use of unleaded gas. The rated power dropped in 1972, but that was due to the change from gross to net rating (and after that, they were emasculated further almost every year
If I'd feed it a lubricating supplement, I could put in pistons off a 70, heads off a 472 from that era, and be above that. And then fuel injection, or . . .
800hp off a 500 with a quadrajet carb is not unrealistic. And this has a *real* turbojet 400 transmission, which should handle that kind of power--but what would I do with the power? Stock, this thing can slam this 5,000 lb behemoth to any speed that I'm willing to pay the gas for . . . these beasts were designed to cruise all day at 100 with the AC running . . .
I don't plan on it (but I may do the 472 heads for fuel economy).
The stock engine puts out more than enough power for anything I'd really want to do in a car that big--it will never whip around a corner on a mountain road, no matter what I do [hmm, except flying off the curve, of course :)].
And you can get the power out of a smaller engine today, but it was possible then, too--but there's really no substitute for cubic inches. You *can* tell the difference in ride just betwen a 350 and a 400. There's just nothing like the casual, effortless acceleration of a large eight. You can match the acceleration, but not the ride. (or the fuel consumption
hawk, off to play with the carburetor.
