What kinda power is the 460 pushing?? Track times etc etc...

What kind of times is he hitting? A Stang with 460 better have one hell of a motor since it is so heavy. If he is running 12 you won't have to work hard. If he is running 10s you will really need to do your homework. I don't have to many answers for you but all of this is info you will need to consider to know what you need to do to be faster than him.

P.S. Why don't you want nitrous? Is that not real power? Just curious.

i have not seen it run but its just a built 460 as far as i no and it never been on the drag strip the guy that owned it be for him sould have run 6's on the 8th and my problem with NOS is that bottle runs out

A built 460 isn't enough info. I would say if it is a mostly stock 460 he is only running 13 or high 12s. Have you raced him? How much did he beat you by if you did? You might just need an exhaust, intake, tune, and other small things and spank him. You also might need to SC a built 408. That is why we need to know what you are up against.

Not trying to be too big of a jerk but please type with some manners. It is very hard to read your post with no periods and so many messed up words. Not looking for perfection just better so it isn't so hard to understand what you are looking for.

A big block powered fox is nothing to take lightly. It doesn't take much to get something like that into the 9's. If it's rebuilt, those things can go to about 557ci on a stock block, and the cars themselves can get under 3000lbs pretty quickly.

For a LSx, a healthy 370ci motor with say a 200 shot would probably do the trick, but to get your e.t's down, it's really going to come down to the suspension.

408"-427" with L92 heads and cam, your choice of intake (I like the 4BBL throttle body and single plane myself) 1 7/8 headers. Suspension tuning will be a bigger factor than power.

if you want to use boost and a built motor, i hope you have some deep pockets. but heres my ideas,
low compression (6.0L iron block) 408 with a big *** turbo on there or an F1 procharger.

or the N/A route, a 454 LSX block ~13:1 CR on E85 with some very nice heads on it. getting all the power to the ground will be the real trick.

even if the motor is heavy, the fox body is light. Pretty much cancels that out. op look at the forged iron 427 shortblock from schwanke engines(sponsor)3499.00. get a set of l92 heads/ ported l76 intake, custom cam, and a 150 shot of drugs. You should be able to get 600whp for about 6k when it's all said and done.

was i the only one that read that the previous owner went 6's in the 1/8th????

id say the cheapest route is gonna be a 5.3 with an ls6 cam,and an mpt 70.....screw building a big cubed engine..lots of super fast stock engine turbo cars on this board...you need to do tons of research...gonna take a nasty *** ride to take down a big block fox ....

was this a serious post?????if so id act like it wasnt....

ive seen a cammed 460 in a fox with a relitivly docile setup run mid 7's in the 1/8th at bristol..."slow slow slow track"

sorry I just had to point it out

#1 a mild 460 BBF can hit the 500hp mark EZ with Torque to boot.
And when you stuff that between the shock towers of a Fox-body stang that can weight in at under 3000lbs with the BBF, that CAN become a tall order to try and fill.

An LSX answer to that IMO would be a big c.i.d. LSX (454). there is no replacement for displacement. you will need to get that F-fody on a diet and get the suspension hooking.

Until you really know what he's running, then it's all guess work. But, really, who gives a **** if he's talking down your car. **** him. 460 in a Fox body sounds like a race car and not a nice street car. Now, are you building a race car or a nice street car? If I were you, I wouldn't worry about some joker in a Mustang that needs a 460 to be fast. Just build you a nice, reliable motor and have fun. Trust me, there will always be someone faster, someone that thinks they're faster, and dumbass kids without a car that will still talk **** about how they are faster on their big-wheel!

Now, building a nice motor. First, what's your budget. Horsepower costs money. You got $2 grand? Then a nice LS1/2, with ported heads, decent cam, and good headers will get you in the mid-to-low 11's. Got $5 grand? Then a nice forged stroker LS2/LS3 will get you an to mid-to-low 10's. Got $10 grand? Then a big-cube forged motor (think LSX 454) should be getting to into the 9's. By now you need rear end, suspension, roll cage, etc. Still a street car?? Got more to spend?? See where I'm going with this.....

It would take a bit of money to make 500 hp out of a 460 They just did one on Horsepower TV. I will have to watch the episode and I can tell you the numbers. I think on the cheap they made high 300 hp and with the fairly high dollar build up they made about 500 hp.

Like I said from the begining everything is guess work. Till we know what this BB Stang is.

Sorry I just looked up what I could find and they made just over 600 hp on the high dollar build. A stout 408(the motor I am building for my truck) will put out around 600 hp at the crank. Anything less and it will only be easier to match his performance.

Rude. Sorry, just had to point that out.

seriously, how much are you planning on spending? are you ready to dive into something like this? the truth is you could probably take him out with a heads/cam setup on your stock motor. it all depends on how much care you put into the rest of the build. if you wanna suprise the hell outta him, just keep your build simple, cheap, light, and keep that stock motor and rub it in his face when you walk all over him.

of course, if its a 557" motor, you're gonna need a little more than the stock motor. hah.

if you got the cash build you a nice 383 stroker with a billet 400 small block crank nice billet dome pistons 2.400in intake valve 1.800in exshust vavle thats the partical details on the powerplant id build to take it down perhaps a 600/570 cam set up of course from billet steel

i know im not going to into detail but i feel lazy tonight lol
