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.
 
I have seen low 13s on street tires with the trickflow kit. No guarentee that your car can do that because there is a bunch of things involved with 1/4 miles but a good guesstimate.

350hp and 370tq are definately engine dyno numbers. You will see 280-310hp at the wheels depending on condition of the motor, supporting mods, and state of tune. 12's have been attained by many on this board with around that power level with a good set of rear control arms, sticky tires, and good driving.
 
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.
