help me prove chevy guy wrong

Who cares how fast the chevy guy thinks he's gonna be, you should just build a stang with half the mods he has and then make him cry... thats what I am doing, this guy I know is building a Iroc camaro with similar parts and like 5 years from now he might be finished, and I will still spank him thats whats sad. My best run N/A so far is real close to his best time Spraying a 100 shot AND his motor is built. Not to totally bash chevy, but it just seems that either all f-body guys can't drive OR stangs are just better built cars IMO. (theres no way I can get flamed for saying that here can I?)lol

He is probably around 450-500hp.
But he would be shifting too low (don't tell him that) and the converter is way to small (he needs a 3800 to 4200 stall converter with a T-brake).If the rest of the car is set up o.k. probably mid 11's.
Of course that would be assuming that the motor actually has what he says and he is a good driver.But you didn't say what size carb he is running.The big cam and single plendulm intake will hurt him bad thou.He woun't see peak tourqe till 4500rpm,and with a conveter that small he will launch like crap.It will boug off the line and not get moving until passed the 330ft mark.You also didn't say what gear he is runing.If he is runing 4:11's or higher he might not boug horrably off the line but it will sertanly show until he has at least a 4.88 gear.I can see how he intends to beat you,he will shift at 5100-5700rpm's and be at 4500 or so rpm's when he shifts into third.Then his all-top end will pull hard the rest of the way.If you intend on beating him,you'll need to out rpm him.If you can beat him past the 660ft mark you sould have it in the bag as long as you got more gear left.After the 660ft mark he will be like a big block and start really moving,so the first 1/8 mile is were you got to pound him.Then just out run him to the finish.
