At the strip I use the same launch technique I use on the street ;
off idle and nail it = 1.7 60fts
The only difference is how long I keep my foot into it.

1.7 is pretty good traction! ;46
Your ability to use torque is dependant on your tyres. Anything over idle fries mine, which is pretty cool until you can't see where you are going and then it snaps into second and sends you sideways. They hate it when I do that at K Mart!
Your stock intake runners will act as your rev limiter. You can build an L98 for HP but will be a dog over 5000 rpm - with stock runners it is better to have good torque t'out the rev range. (IMHO)

I have siamized stock base ,SLP runners, ported plenum and headers on 100,000 mile engine.
Even with these mods still does not make power over 5000 RPM just makes a lot more than stock below.
The long runner setup, even modified does not lend itself to big revs but makes a sh#t load of bottom end torque.
As stated above it depends if you can get that torque down to the road.

Are we talking about the same thing?
I am talking about traffic lights at the street... and just cruising off without making a scene... ie Revs and SMOKE... :-)
these are two different environments....
My L98 has not gone over 4000rpm except when I agreed to the dyno tuner wishes.... and he found my L98 was puting out the same HP as when it left the factory.... about 160 flywheel hp.
actually I envy you... 400 RWHP is more than enough to please anyone... male or female... AND as they say... what you can't put on the deck is a waste.
So pls share with us what you have done to get 400 RWHP out of an L98?.... and I am hoping that ya dont say ... "i got a crate engine" :-) ... cos I (and the originator of this post) have an L98 to improve without expending too many bucks for the bang....

the problem that i have racing off the lights is that with high tyre pressure,cold tyres and the usual build up of oil and crap at the lights i just fry the back tyres into a cloud of smoke, so i tend to wait till the mid of 1st gear before i start to feed the power in.

about 18 months ago i blow the old motor up at a corvette drag day so i was in the market for a new motor.i purchased a 4 bolt main block and strocked it to 383 and flowed the alloy heads that were already on it and put a solid roller cam and so on and so on.but the main difference is that i run a miniram intake which is a aftermarket manifold that replaces the long runner TPI injection that you have,and allows me to rev to 6500-7200 if needed.although the motor makes around 500hp if i can improve the computer(eg haltech) and replace the mass air flow meter with a speed density system the engine builder said it should make 560-580hp which would give me about 450 rwhp.easily enough to smoke both supercharged and big block cars.
