the 3800's just a descencdant of the Buick 3.8L, nothing against it. Hell, it still produces nearly as much power as an 4rd 5.0 motor, and it's figures are consistent with an older 305! That's not too shabby in my book. I've always been curious to see what someone would do with one of those 3.8L Camaros out there, seems like it'd be a decent place to start. Big question in my book is what did they cheapen down. If I were running a full 15 PSI, the old style "steel plate" pistons would have to come back. I would definitely inspect the rods, see if the good design of the 3.8L remains. Stick a 4.3L Chevy and a 3.8L rods side by side, you'll see what I'm talking about, no comparison. Enginewise I'd end up looking at the 10 second Grand Prix that was on the board a long while back.

Here are some 11 sec stock shortblock 3800s, not bad at all in my book and it speaks that the 3800's still got the potential it's older 3.8 father does. A stiffer block then the 3.8 would definitely be a plus to me honestly, something that'd take 6-700 horse without needing a girdle. Maybe do something *really* radical and throw a set of heads similar to an eccotec's on there, really spice things up. Should be able to get insane performance with the kinda flow something like that would provide. Team it up with a *built* (Sunshell, billet servo, and so on the whole meal deal) 4L60E and you've got a real winner in my book.
What the GN would look like today? I'd like to see something similar to an early 70s GS rear end wise, mount it on a C6 chassis round it out with the front end styling of say a 280-ZX front end with the characteristic hood scoop. Stick with either an earlier GN's wheels or the "T" wheels though. Something that would truly say "bad mother F**ker" if you will. Interior would be either a black or grey dash, probably grey seats power 6 logo in the wheel center (would like a sport wheel, but with air bags it ain't gonna happen) Power would be about 400 flywheel stock, or in tradition of GN/corfette relations 450 rated at 400.
Someone photoshop me a prototype and we'll mail it to GM as a "community service"
