I like to keep as many variables constant as possible.
Fuel level- half tank
Tire pressure- 19 psi is what M&H recommends but I had better results lower.
Pick a launch RPM and see how it works, start @ 2500 rpm and work up and down.
Always run in the DR/slick lane never in the street tire lane, let the big tire cars literally pave your way with rubber.
If you have a bad track surface you'll have to adjust
Like anything practice makes perfect.
Factory 3.31 and 20" tall wheels and tires are not a great combo- 3.73 would be better suited with a 28" tall tire like the M&H your running. I shifted my 5.4 @ 6800 rpm religiously I would think the 4.10 might be a little short on the gear but if you can hook it then it's all good.
Burn out-
I like to clean the tires off in the water and use the spin momentum to carry me out of the water. Then start my burn outside of the water box. With 4.10's I'd use second gear.
Launch technique-
Don't push the clutch pedal all the down at the starting line. Ease into pre stage and slightly depress the clutch until the car stops moving. Now pre staged, rev motor to launch rpm, slowly release clutch and ease to deep stage with rpm at launch point but only push the clutch in to stop forward movement, not all the way down. Launch from the point of friction.....
Great job ... good to see your back out .... but what do u know LOL ..... JEFF
Nice times!
Sadly......yes, it's the main issue now.stock clutch?

Maybe not if you swap gears, I've never had a clutch issue at the strip, several 10s passes.
Only one time on the street testing launch control the pedal wouldn't return, I had to pop it back up, several thousand miles and passes since that one time.
That said, I have a SPEC sitting in the garage.

With a gear swap and just street fun and rare strip use, who knows how long the stock one lasts.
I don't understand why anyone would regularly run at the strip with the 3.31s.
Its 100% guarantee to swap clutches, ask NJTony.
Its a mechanical advantage thing, 4000# with 700tq in a 2.66 trans/3.31 gear equals clutch killer.
