OK,
I wonder what my trap would be with a with a 2.07 60ft and traction before 3rd gear. You have more grunt with the extra cubes (no replacement for displacement) and you have more power hiding in there once the AFR is leaned out. Shoot me an email. I'll start looking for the cam card.

 

i sent you a pm...only one way to find out bout the trap, get some BFG's

Edit* I got my new tune so ill shoot over to the same dyno to get comparable results...

 

Nice numbers. I dont know if your gonna hit 400rwhp by leaning it out one full point. More like ~8rwhp from my experience. I had the LE 2 heads from 2 years ago and an EX230/236 ground on a 114LSA. I made 368rwhp/336rwtq with an A/F below 10:1. I leaned it out to 12.5 and I made 383rwhp/353rwtq on stock bottom. I also ran 12.5 @ 114mph on dr's with a measley 2.07 60' with 368rwhp/336rwtq.

 

My cam is just about the same size, i really can care less about the dyno numbers, my goal is high 11's w/ 117 or better. So if i get it completely tuned out, and still cant hit it, im getting draglites and skinnies up front. And a 9" w/ 4.10's. The gears should put me right in my power band at the end of the 1/4, 6300 rpm as opposed to the 5300 im seeing right now crossing the line.

 

I edited my post above...I ran the 12.5 @ 114mph (consistent 114mph all day) when I was only making 368rwhp/336rwtq. If I went back in the 383rwhp/353rwtq trim I would have trapped 116-117mph easy. Just by leaning it out I picked up over 30rwtq from 2500-3000rpm.

 

those are some good numbers, how does the car idle? I wish I had some good movie clips of my car cause it sounded wicked. Gotta love those nice flat torque curves LT1 383s give ya! Your car should go high 11s easily just with traction as it sits. I was pulling high 1.7 60's with BFG drag radials on the stock 10 bolt but I had and auto with a high stall. With 4.10s and a little more tuning your goal should be achieved. however you guys are making me wish I had a 6 speed lol. wanna trade trannies?
