Sounds like someone who would & should know. If your going into a fight knowing a few things your facing it helps. As with other things this thread maybe useful in the future. 550 @ the crank minimum is Hardly asking much from a 6.2 with correct parts. Just because you have the ability to make more Hp with a 6.2 vs a 5.0 doesn't means it will be faster. The entier car must be looked at.......Hp and dynos don't win races just tools to help a person with a properly set up car win. Weight and gearing are the 2 most easiest factors to do and most times overlooked for the idea of more Hp, which isn't bad in itself.
i tease
How so?
who's doin that?

No Problem Hio. My thing is I can remember when I 1st got into the Ls engine I was @ around 550 with a 383 stroker and Ported E-tech heads for a Gen 1 sbc Hyd roller. I came over just because of the heads. Now if a Ls3 with a cam can make a Honest 550 to 580 with just a cam swap. No comment. Heck a stock Ls3 vette made 518rwhp with a cam, ported heads/milled a bit and a six spd. Come on now guys. 243's with a better intake and cam and you have the same basic engine size of a 6.2 . Just read this and think of 243's ported with a good intake & TB. It would be roughly about the same the 243's may make more tq lower. Even a stock intake is used.

Well ya and I'm sure your car looks like Swiss cheese on the inside as well. A (for example) 2011 mustang has the power to weight advantage over an fbody stock for stock. Add in bolt ons, converter and gear and the coyote has a clear advantage power vs weight when compared to a fbody with bolt ons. Either the coyote owner couldn't drive, had no traction and/or like I said, your driving around in a piece of Swiss with wheels.

Sam Strano who builds and races cars for a living only ended up at 3300lbs.....Quoting his car,
"After two solid days with the guys up @ UMI, we are done. Car has new K-member and upper and lower arms installed. And with 1/3rd tank of fuel, a fire extinguisher, a harness bar, and not my lightest wheels it rang in @ 3301 on their scales. I'll rescale it to corner weigh it and align it sometime in the next few weeks.......
"There is no secret. Light battery, no rear seat or seat belts, A/C is out, radio is out. A/C will go back in at some point, screw that. And it was light on fuel. No massive rear axle, light wheels, a compact big brake kit, not overkill, etc."
So 3300lbs with a tubular front suspension and K member, no A/C or stereo or rear seats etc. etc. People who run hero times lie about their mods, lie about their weight, or what they did to get to 3200lbs or less, or do stuff that 95% of the rest of the community doesn't consider bolton. A supercharger is technically a bolt on, and doesn't require removing of the oil pan to install a crank scraper LMAO. Is that fair game now too? Don't even bother with going back and forth about it. To each their own and they can do or claim whatever they want.

People lie about weight reduction and hacking up their car all the time.

Below is EXACTLY how to do it.
yea....it's not even that difficult.
or maybe you just don't know how. It's ok...that's what the forum is for.
it's easy to get these cars to 32xxlb or less and keep your radio, ac, rear seats. Just have to pay attention to what your doing.
light battery/light clutch/jack-spare! is 100lb out. Now my carcwas 3430 stock. So those alone put it at 3330. Just doing the simple egr!/air pump!/ full exhaust should net about another 50 give or take.....that puts one at 3250ish. For guys that want drag paks on their car that can push them into the 31xx range....still having the stock k, stock bumper supports and full amenities.
now do a k member, lighten yours or buy lighter bumper supports, front sway! for the drag guys. Look for all the little gizmo **** that don't matter. Add a lighter hood that takes 20lb off the nose where you don't want it anyway. Now you have a 3100ish car maybe less. Pretty simple.....and still have all your amenities.
no reason to argue. It all adds up.

Regarding weight reduction, it seems simple but it's easy forget to remove clutter and stay vigilant about keeping it gone from inside the car before racing. Things, like water bottles, notebooks, books, jumper cables, that spare 1/2 quart of oil, tool box, first aid kit, junk in the glove box, junk in the console between the seats and the half dozen CD's scattered about. The inside clutter can end up being 10-25 pounds or more sometimes.
Oh that reminds me I need to get that box with 5 cast iron skillets out of the Z28

That's why i leave the jack/spare in mine. 
....that creates a little butt hurt for the funz also
And still come in at about 3250 with me in it....and my ac....and my cruise....and all muh seats. Only thing it's lacking is airbags cause i didn't want those tearing up my car and spitting shrapnel in muh face.
there is weight all over these cars. Errytime i work on mine the goal is to remove a little weight from something.

Yea the addition of e85 alone woulda probably put me at 460whp with a bolt on ls6.
1.9 rockers, vacuum pump and some rocket fuel woulda probably nailed down another 20whp.....what was Dspeck saying about not saying......i missed that.
