What should I change this year

Last year I had the heads ported which improved my 1/4 times a solid four tenths. Now I want more of course. My setup:
LA 408 with forged stuff, ~11.2:1 on pump gas
Mopar .557 252*@50 solid cam
Worked over Eddy heads by LaRoy
Ported Air Gap
Bigs stage 5 750 double pumper
Hooker headers
Mild 727 auto shift with Cope 4500 rpm converter
4.30 gears
28x9 slicks on steel wheels all around
Calvert bars and shocks

I'd like a drop a few more tenths off my 1/4 times. The options I have considered are:
Drop the stock 14" steel front wheels for light drag wheels and front runners
New cam (lunati recommended their voodoo 30200743)
Methanol
New 727 (won't drop much if any time but I do have 8 seasons on my current one)

Thoughts? Any other suggestions?
