5.0.....full on drag car. Help me set it up.

[Dark_5.0]

Here is my set-up

E7's Ported and polished
Explorer intake 3/8 inch phenolic spacer
65mm TB and 67mm EGR
Aeromotive FPR
underdrive pullies
electric fan
1 5/8 equal length headers
O/R X-pipe
2 chamber flow masters dumped
steeda tri-ax shifter
Ford racing clutch
3.73 gears and slicks
removed sway bar
sub frames
steeda lower control arms

My 5.0 is still speed density and still has the stock cam .

I want to keep my 5.0 all engine and run in the N/A V-8 class at the track next year.

My goal is to run mid 12's @3000ft with the stock heads.

Here is my question.

I want to change from 3.73 to 4.30 gears and run 27 inch slicks.

That would put me crossing the line at 5600-5800rpm's in 4th. What cam do I need to keep it from dying out at the end of the 1/4.

If anyone has any opinions or criticisms or alternatives on my 5.0's set-up. I would love to hear them.

Thanks,
