CAM Question

I am looking for feedback on a cam selection for my big block build for drag racing. Basic info:

• 460 iron block +.060
• D3VE iron heads, ported exhaust, 2.19 intake, 1.71 exhaust,
90 cc chamber, 1.73 rockers
• 11:1 compression apprx.
• Weiand Stealth Intake (dual plane)
• 1000 cfm carb
• C-4 Auto Trans, 4.57 Rear Gear
• Vehicle weight – 2800lb.-3000lb. Back half car

Utilizing the Comp Cams cam selection software, their recommendations for a solid lifter cam “best fit” are part # 34-343-4 (.640” v.lift, 260º dur., Int. & Ex.) or #34-652-5 (.589” v.lift, 256º dur. Int.; 615 v.lift, 266º dur. Ex)

Any experience on comments on these two cams?

Their software will ALWAYS lead to a "catalogue" camshaft which best fits your parameters however, a "custom" grind cam is probably better performing in 95% of all big block Fords.
