How fast with DD 302 h/c/i

Hey all, I was looking at the Trick Flow head, cam, intake kit in Summit that advertises 350HP 370 torque with 9.5:1 copmpression. With 3.73's, street legal drag radials on different rims, and a little practice how fast can a fox 5.0 run in 1/4 mile? This is a daily driver so I cant go with trick springs, shocks, no interior, etc. I have sport springs and shocks, rear control arms, and subframes. I can go to a 1/4 mile track where its run what ya brung all night for $20. It just needs to be inspected to verify its "street legal." Im trying to convince my little bro to keep his 85 GT and we can make it a 12 second car yet still be his reliable commuter car, instead of getting a SN95.

Thanx this is what Im wanting to here. I was looking at the Trick Flow kit mainly because its a "kit" for about $2,250. If I can find a head, cam, intake kit with roller rockers that will cost similar and make a little more power I'll definately consider it. I just cant go radical with it.
