no difference besides how the accessory's are configured. same heads/tune/cam/intake/rockers/pistons/ not a dang thing different. sorry had a guy argue w/ me that the ls1 in the f-body was inferior and they did not have the same 350 hp.

But isn't the F-body rated with just a bit less HP, because of their restricted exhaust system? The engines are the same though! 
If I ever sold my C5, I would be driving a 2002 f-body for sure! Like they say, it's just a steel corvette!!

no. f-body's consistently dyno a little higher stock than c5's because the solid axle allows for less hp to be sucked up by the drivetrain.

Here's a related question then, why does the '99 Corvette LS1 engine cost more than all the other LS1's? What's so different about it that rates a much higher price?

and i thought thay always purposely underated camaros numbers to make the vette look better since it was over twice the price and alot of ppl just look at wats got more power

My 2002 Z28 6-speed dynoed 319 RWHP bone stock. With only an air lid, sub-frame connectors, SLP LM and drag radials, I was consistently running 12.50's-12.60 at 1400' elevation. It had 353 RWHP after the mods. I have lost count of the stock C5's that I blew away at the track. Here are two videos of me at the track and dyno with the 2002 Z28. Awesome car, but not the quality of a Corvette. The engines are the same, btw.

Even though I now own a Corvette, it was fun to watch C5's try and catch me at the track. I have driven C5 ZO6's and they are not quicker than my Z28. They are pretty equal but if push came to shove, I think my Z would beat a stock ZO6.
Either way, 353 RWHP from a lowly Z28!!

your car w/ 353 rwhp trapped 110 now watching the video's it's obvious you can drive fine so i'm not questioning you in that aspect in any way shape or form. but 353 rwhp does not give you 110 mph in a f-body you should have trapped a little higher than that. your car ran good as is obvious from the video but those dyno numbers are a little high.

There is DIY "drill mod" to fix this, but I never did it because I was happy with the performance that I had and plus, using drag radials with no spin off the line (typically), I didn't want to shatter my 10-bolt. For those ET's, the trap speed is typical but if I could have launched hard at 5000k and got all that power to the wheels without the clutch slipping, my 60' times would have improved by probably 3-4 tenths. If I launched at anything higher than 2500 RPM, that damn clutch would slip and wouldn't help nor hurt my 60' times.

Should be, many trap well over 110, even in that DA. They have a huge gearing advantage (for a stock car) with that MN12 tranny. I see we may be getting into the whole quicker/faster debate again though so just food for thought, don't want to kick start that debate again

My original point was just that LS1 engines are the same, with the exception of the 2001 and 2002 Z28 because they came with the ZO6 manifold which was worth 15 extra HP over previous years LS1's. Either way, the LS1 is a powerful engine which responds to bolt-ons very, very well.

Not at all. When you launch an f-body 6-speed off the line, the clutch was made to slip due to added restriction, and that it does! The rear end is warranted, but the clutch is not. GM did this to protect their very fragile 10-bolts which are prone to shattering under load with little to no wheel spin. My 60' times were 2.0-2.2 because of this.

I love everything about NC except many of the old, OLD laws still on the books that don't make any sense at all. When I first moved here I worked as a corrections officer for the Sheriff's Department and man, the old school laws really screw a lot of people, BAD!!!!
