Ok, can someone explain this to me? I have heard people say that a Lightning can run high 13s stock. An then you can add just a chip an maybe a diffrent pulley an then it runs high 12s. If this is so true, then why are all the Single cab silverados with a SC an tunning not making it into the 12s. Cause it seems like it takes more stuff to make a chevy run 12s then it does a Ford. At least gudging by the Fastes Truck list an what all you other guys say on here.
Why is that?
I know chevy has awsome engines, so whats the problem, tracshion maybe?
Or if i am wrong someone please help clear me up on this, thanks

 

Well not only traction but the fact that the ligthning comes with a heavy duty tranny and ours are crap and then there rearends are also alot stronger.

 

Considering most lightning owners post stock dyno numbers of around 360 hp and 450 tq at the rear wheels, I would think they should run faster than they do. We have trucks here running low thirteens with much less hp and tq. Explain that.

 

Cuz it has a blower!!

 

 

I'm running 12's with my blower.

 

13.98@ 98mph (1.98) - the mph shows that the air was horrid. florida heat kills the hp. stock Ls weigh 4700 lbs before you stick in the driver. stock 305/45/18 F1 tires help dead hook. still a leaf spring. still really just a silly f150. 358/430 at the rearwheels here factory stock. stock rearend, tranny, and convertor are great pieces. i dont ever expect to mod them.

if you think they should be faster, well, what should it run? 13.7@100 is more common among the good air drag strips (not in the FL swamp) in the cold winter/fall air.

standard pulley, chip, airfilter (not really needed) guys run 12.9-12.7 very easily on stock tires. get you into the 410+/500+ at the rearwheels.

 

The fact of the matter is that the Lightnings were built for performance and speed. The silverado is built for regular truck duty. Slap a blower on there and it is still a truck built for truck duty with a blower slapped on. I would think that the stock lightnings cam(s) are more performance oriented as well.

 

yea, try towing with an L with say, 7-8K lbs. lol. it can do it, but it aint pretty! also here is another thought. the L can run 147 mph top speed. what do the GM trucks run top end?

one more thing. lets not forget teh L is a total combination. the wide wheels, huge tires, hard hitting convertor, big tranny, big convertor, tuning, Bilistien shocks, sway bars, etc are all focused on speed. not general truck duty.

 

What's the L have for a stock converter?
