Gotta be the same car in both vids since there can't be two knuckleheads who thought 4.56's would be a good idea in an 03 Cobra
I would need to find my dyno sheet but when I was stock I had 300 lb/ft of torque from 2100 RPM up to a bit past 5K. It was quite literally a torque plateau.

LT1's make peak torque by a mere 2400-rpm where as an LS1 will peak at about 4000. That's why LT's feel stronger on the low end. However LS1's make more torque overall just a higher peak rpm.

Okay, you know my setup, on 26 inch 10.5 Mickey ET Streets.
AFR 165s, ported Cobra intake, TFS 1 cam, home-made 3" CAI (4" soon to come) and K&N filter (Anderson is going on when the new MAF does), BBK 1-5/8 LTs, custom 2.5 X pipe, 2.5" dynomax ultraflows dumped. 3.73s out back.
I will run, I have been convinced. WSSick, be sure to look for the black 95 Cobra on silver Cobra R's and 15" tribars for rears that's slow as **** because it is still running on the STOCK TUNE!

Thank you for that perfect explanation.

As long as this damn rain holds off, Ill be there too. Look for the slow blue LS1 catfish looking like a newb! (1st time down the track). Maybe well get to line up enxt to each other Should get chilly tonight, maybe 60s, so should make for some good runs.

Oh no!!! Make sure you use double protection so you don't get any blood on the seat when your cherry gets popped.

Rain is putting a G'Damn damper on these plans. The radar looks like we will be hit regardless, so we are not going anymore. It would be a royal PITA to rush home (half hour away) right after work, put on the DR's, take **** out of the trunk, etc., and then have it rain and be canceled. I will be to STL though for sure some time soon, we should run some

Here is the same 03 Cobra losing to a Challenger with some mufflers.

Cobra pulled pretty good. A set a drag radials will change that story.
