Then I found this info from Popular Hot rod magazine when they tested both cars. I have seen numbers all over the board for all cars, depending on the magazine that did the testing.
Camaro SS396 396ci/375hp n/a 14.5 sec @ 100.6 mph PopularHot Rod
Camaro Z/28 302ci/290hp n/a 14.7 sec @ 95.9 mph PopularHot Rod
Not sure how valid any of this is as I've also seen one magazine report the 87 IROC-Z with a 350 run 15.3 @ 98, while the 305 ran 14.9 @ 95 and then another magazine will show the 350 at 15.7 @ 96, with one more magazine showing the car at 14.4!!!  |
I think those times (PHR) were more realistic with a good driver behind the wheel. Likewise with the IROCs, mid-14s.
I think for the most part, when both were run at the same time, SSs were a tick or two faster. LT1 SSs were a little faster; LS1s, though, were about the same unless you opt'd for the SLP catback - but then, it wasn't strictly an OEM car, since it has aftermarket parts on it. That's debatable I guess though.
Using the LS3 as the higher revv'ing more powerful example just makes it an LS7. With the durability testing requirements that I can remember reading about, it takes the forged crank and titanium rods for that LS7 to maintain that level of reliability that they are looking for under the testing they do. By making an LS3 rev' higher and make more power, you're talking about pretty much building an LS7, and that's going bye-bye.
I'm interested in seeing what replaces the LS7. Is that going to be an LSA or Gen V? I think this will give us a better idea of what is going into a Z28 down the road. I think it'll probably be a Gen V because they want a Z06 to be light, but I don't think that'll be the way Z28 goes. Maybe they'll just get rid of the Z06 altogether... Anyways, I think if GM keeps the Z06, there's a good chance they'll get that into Camaro somewhere to help spread out the R&D money for that engine.
I still have my own personal favorite for Z28, but to each his own
