420 to the crank?
I got the new Mopar Muscle Magazine...they took a stock Hemi, dynoed at 249hp 263tq (rear wheels)...they put the Comp XFI 260 cam with Comp valve springs (same as GM's LS-1), TCI Torque Converter, CNC Ported Heads, ASP Underdrive Pulleys and Dynatech headers. They also tuned the ECU. They didn't say if they put a CAI in, but I guessing they had too. In the end when they dynoed...it came out to 318hp 333tq to the rear wheels. If your real serious, I would get the magazine and read the article. It's really cool. The only down thing is $$$...They didn't mention any prices, but like everyone says: "Speed cost money, How fast you wanna spend"

318/.72 = 441 HP... even assuming 21 "fake" HP due to driveline improvements that is still 420 HP with the exact mods I recomended....

Interesting (but, rather sad)... that the final Mo-power was about what a healthy, stock LS-1 does--AFTER all the changes to the hemi.
With just the headers and a decent professional dyno-tune the LS-1 will do on average an additional 30 hp and a few more than 30 #ft at the rear wheels. Seems to me that Mopar must be pretty conservative in their factory camming and tune. All the more reason we need the 6.1 from big "Mo."
All the best.

Ls-1s run on premium not midgrade....
Ls-1s are generally attached to more efficient drivelines (30-40 HP loss through a T-56 over 90 through the mopar tranny)
GM lied like hell about the output of most of their LS motors. F-bodies have been known to put to the wheels what they were rated for at the crank.
