364 ci versus destroked to 332
I'm contemplating building a new forged shortbock for my lq4, s475. I have a powergilde, 3.73, 27" tire (planning to use 28"). My car weighs 3217 with me in it. Only 1/8 mile track, street driving. With stock 317's, could a destroked 6.0 benefit me more with powerglide in 1/8 mile run? My s475 is t6, 96mm 1.32 a/r. I have tick turbo cam and ls6 intake, e85, non intercooled. A new cam would be needed. Would have to change heads or port, and change intake to gain benefits of more rpm? At the end of the day, would destroking be worth it??

Rpm is limited by the valvetrain
The shorter stroke doesn't mean you have the ability to turn more rpm, it means you'll need to
You're spending money to give up power doing the destroked deal

I have to agree with Blown06 on this. So many factors, adding power doesn't make all the difference.
In all reality if this car is being built for the 1/8th mile, then you're going to need to be able to hook, and make some steam quick. Go with the 364 (or 370), get a good cam, and let er eat.

If I ever throw a turbo LS in my dragster it will use a 4.8 crank. I won't need the sub-3500 RPM torque advantage, and I could use the mechanical advantage of a longer 1st gear and a better rod/stroke ratio. I might actually throw in a gen-4 4.8 to kick things off and see where it goes from there.
In a heavier 1/8th mile car, the extra torque might be of an advantage.

At the end of the day, if you dont have the power, you wont pull the speeds regardless of where the rpm's are.

Longevity-wise, the short stroke engine is taking less of a mechanical beating, in juxtaposition to a longer stroke motor. The working angles are better with the higher rod ratio so every part of the rotating assembly is under less stress during every motion.
To the OP,
Destroking may help traction in a lightweight chassis, but if you aren't having traction control issues, then I would really be dubious of dropping any displacement with a big 96mm/1.32ar turbo.
