Ya I know the truth lingers around for a wile..

assasinator

the s197 chasis was originally IRS and converted.

i expect a few pounds(50) lower weight for the v8 gt.
i expect the 4 cylinder turbo to be around 200 lbs lighter.

3400 lb base gt and 3100-3200 pound turbo 4. the turbo 4 will wind up being the fastest fully modded in a straight line and certainly around a road course.

450-500 rwhp on e85 is just average for a turbo 2.3 liter.

Is this dude for real?

I sure hope not.

I'm honestly surprised the 5.0 didn't do better! Needs some efficiency mods. Big wheels, etc., not doing it any favors.

This thread has turned to ****, like most on this forum, but let me put it this way for everyone that's saying the LS3 is super cheap to mod. I ran DOOR-TO-DOOR with my buddy's LS2 'Vette M6 with intake, axle-back, and tune. I posted the video on this forum. That's $500 of mods to run with what should be pretty damn close to a stock LS3 'Vette. I weigh over 35xx lbs, and he's around 31xx/32xx.

The 5.0 may not have as much torque as an LS3, but all of those cams and valves really start to shine up top. Evan's BOSS, and other 5.0's with the CJ setup, make real power all the way to about 8k. That's the benefit of this motor over an LS. It's at an inherent disadvantage with only 5 liters, but you don't need cams to get top end. What's harder, a cam swap, or taking off an intake manifold?

It's a different type of motor and each has their advantages. This video makes the C7 out to be fast. We all know that for what it is, it isn't fast. I think this 5.0 is just slow. As with LS1's, it's all about the setup.

Well said

It's actually very far from the truth

To the bolded part, me as well - hence why I posted the video. Was not trying to create an LS2/LS3/LT1 vs. 5.0 debacle.

To be honest, a stock M6 LS3 would still likely have about as much power as your buddys light bolt-on M6 LS2, if not more. The LS3 is an awesome engine.

The C7 isn't fast "for what it is"? Are you kidding me? I'm not trying to down the 5.0 or anything, but all of that appears to be excuses as to why it lost.

LOL at the c7 being "slow"

Its a shame that the rear end of these cars are so ugly. But man the inside sure is nice.

Looks are definitely personal preference - I personally liked the design change.

The interior is leaps and bounds over the C6. Absolutely loved sitting in a 2LT one and a 3LT one.

C7 ain't all that slow, but the word is that they are have cam issues in the LT1.

Irunelevens

While certainly very impressive, for the purpose of this discussion it would have been more pertinent to post a video of a stock one running 11s.

JakeyLS1

I believe the video is perfectly relevant to his response. He said would you rather change a cam or an intake. Would you rather change an intake or a tune?

but if you wish, the blue c7 is stock tune.

Bone stock LS3 C6s have been in the 11s, so no reason to assume the C7s won't do it as well.

big hammer

stock c7's have ran 11's.

Wonder what a tune only boss could pull off...just for comparisons sake of course . The C7 is no doubt a bad bitch, and I'm sure that with time to figure out the right combo, a full bolt on and tuned C7 in the 10's will be commonplace. Pretty sick IMO.

So the 5.0 weights around 3375lbs with a 3/4 tank of gas? I dont think so. The C7 Z51 is about 3300lbs dry(heavier than a base Vette). I bet the Stang is a good 250lbs heavier in the best case. A non Z51 C7 was weighted at 3217lbs dry.

I read about a 'low pressure' issue at idle with aftermarket camshafts, which is not experienced by well known LSx shop.

Irunelevens

1) I know that both LS3 C6s and C7s have run 11s stock, hence my statement.
2) I was under the impression that the C7's curb weight was around 3,400lbs, my mistake. The lightest of the 5.0s is around that weight, which is why I made that comparison.
