what does he run in the 1/4 mile?

My friend has an 85 GT, he bored it out to a 306, has long tubes, off road h-pipe, flows, pulleys, trick flow wedge heads ( p&p) c-4 tranny w/ 4000 stall, suspension is for drag, 15x10 weld rims w/ slicks and 100-150 shot of the laughin stuff, he also has 4.10 gears in it. What would he probably get in the 1/4?
 
Stock cam? If so your friend will likely run out of motor before he gets to the end of the 1/4 mile. It will probably run in the mid to low 12's with the spray. But like I said, he might need to step down to 3:73 so he won't over rev the engine at the top end.
