C4 weight
I have been unable to find an approximate weight for our C4s. I varies based on engine/transmission/options/etc.., but
Any approximates weights for the entire car with the different years?? (L98/LT1/LT4)

Click the year, then specs. Most of the weight listed, some years have missing data though.
'88 3330
'93 3317 coupe

Here you go. Go to this link, click on the year, you get the curb weight: http://www.idavette.net/facts.htm
In general, it's about 3,300 lbs.

Just my observation/opinion on this...
But it's really not motor weight. The all-aluminum block being offset by the heavy heads, the LT5 and L98 weighed about the same.
However, curb weights are generally established for base cars. So in the case of an L98, that would be with no power seats, no 4 bose amps, no oil cooler, TPS, J55, and whatever other stuff was optional.
The ZR-1 "base" weight is basically a fully loaded car. I would bet that these included options probably add 50-100 lbs to the car.
Then there was the rear wheels, the little extra fiberglass bodywork, the extra quarts of oil and the cooler, etc.
I would imagine a fully-loaded L98 car wouldn't weigh that much less than a ZR-1.

The LT5 was about 120lbs heavier than the LT1, when both were dressed for the manual transmission.
I also have some numbers comparing the LT5 to the L98... the block was 89 pounds lighter, but the extra weight came from: 10 extra pounds from the cams, 17lbs more from the connecting rods, 31 pounds more in the heads, 20 pounds more in the exhaust manifolds, a 25 pound crank saddle, and 26 pounds more in injector housings and cylinder liners.

AQ9 (power seats) 11.9lbs
B16 (leather) 3.5lbs
CC3 (acrylic roof) -6.8lbs
Manual trans -8.8lbs
Z07 22.9lbs
UU8 (Bose premium) 8.8lbs
Even with all those options (not counting the acrylic roof, which removes weight) the coupe only weighs an additional 47.1 pounds. If you subtract the 8.8lbs for the manual trans you have only added 38.3lbs to a manual trans car for all those options.

Is that right? The electric motors, air pump, wiring, switches, and whatnot only adds 6 lbs to each seat?
I'm also surprised by the speaker difference, having removed those things to repair them. It's hard to imagine each individual amp and associated circuitry only adds 2lbs to each speaker.
I seem to recall from Corvette from the Inside the LT5 only weighing about 20 lbs more than the L98. I'll have to flip through it again. Where did you get your numbers from? You didn't account for the wheel and tire differences, though, nor the J55 calipers and rotors vs stock. Nor the tire pressure sensors and whatever receiver stuff there is in the car to monitor them.
The acrylic roof was not standard on either the ZR-1 nor L98 base model.

RE: Lbs/HP. - Divide your vehicle weight by HP. The result is the # of lbs you'd have to drop to have the same effect on acceleration as adding 1 HP. If you're stock, and your car weighs 3307 lbs. with 300chp, then 3307/300 = 11lbs/hp. Dropping those 40lbs for the spare and carrier will have about the same effect in straight-line acceleration as adding 3 1/2 chp. (40/11 or 3.64chp)
