Greetings, kinda new to this forum, but I too have the same goal {albeit a little more extreme) 350Whp/2900lbs
Basically to have one of the most ridiculous N/A Z's out there. That being said I'm pretty sure it's possible...add those bolt ons people are talking about +these:
"Okada Projects - Plasma Direct Coil Packs" - Can be found on 370Tune.com
"Impul - Throttle Body Kit" - Found also on 370Tune.com
"Slightly* larger injectors - Can be found just about anywhere
Use a 93 Octane tune, and a little luck, and you'll be right around 350
Now just try and tip the scales at 29XX lbs..Cheers,
