#21 of 914 Ungodly Power by theo2709 Nov 12, 2003 (8:29 am)
Taken from the Novemeber issue of Automotive Design and Production Magazine:   "When Chevrolet rolls out the 6th gen Corvette at the North American Inter. Auto Show in January, the Gen 4 V8 will have a reported 405 hp, the same as the current Z06. Insiders at both GM and suppliers say the Z06 will have an even 500 hp, but will not be the most powerful Corvette. That prize will belong to the limited production ZL1 which is producing 625 hp in production trim. The Gen4 has thinner bore walls, stronger bulkheads, and retains the cast-in-place iron cylinder liners. The casting process includes a mechanically induced rapid chilling of the bulkheads to promote swift directional solidification of the aluminum and a fine grain structure , both of which improve dimensional stability. A composite barrel crank core replaces the current segmented barrel design, again for tighter and more consistant bore dimensions. The cores are screwed and glued together, the aluminum is pumped in rather than poured, and all the oil galleries are drilled and machined."   Take that Viper and GT!

#22 of 914 I wonder how light the ZL1 will be. by logic1 Nov 12, 2003 (8:35 am)
That level of hp in a two seater streetable car is somewhat difficult to grasp.   What will be left for the aftermarket people?

Pushrods were developed after OHC. So that would make them more modern.
#24 of 914 C6 Shell by theo2709 Nov 12, 2003 (10:51 am)
In another bomb"shell", pics of the C6 body have popped up:   http://www.stupidfastboats.com/dsc00413.jpg http://www.stupidfastboats.com/dsc00415.jpg http://www.stupidfastboats.com/dsc00416.jpg http://www.stupidfastboats.com/dsc00419.jpg   I would just post the pics, but I don't want any copyright issues. Ford went nuts over those insider Mustang photos.   Back to the topic of the C6, I think it looks pretty good, but I don't know if it says "Corvette". We'll see in January.

actually, again ur wrong...   cars in the 50s through 70s had pushrods...OHC became popular in the mid80s and were constantly update
#26 of 914 Yes, but by logic1 Nov 12, 2003 (6:40 pm)
the first OHC was used in the 1920s. Whether or not it was used in the 50s through the 70s does not mean the technology did not exist.
#27 of 914 C6 Corvette transmission by davijon Nov 13, 2003 (12:09 pm)
Has anyone heard whether GM will start using a manumatic transmission in the new C6?
#29 of 914 by regfootball Nov 13, 2003 (11:17 pm)
looks good
#30 of 914 rctennis by b4z Nov 14, 2003 (6:49 am)
What logic1 said is correct.   I'll reiterate, OHC was developed before pushrods.   Pushrods are cheaper that's why they are so ubiquitous, and you why thought OHC was newer technology.
