So my boss just bought a gt 500 and the second I got to work he came out saying his car would hands down smoke anything I own and he would bet anything on that. As of right now my camaro is down because it broke two of the cast pistons right at the ring lands. I was running a hydr cam but now im going to a solid set up. So just wondering if you guys think his car will blow mine away or if I can take him. Elevation is 4400.
My mods are
400 bored .030
Srp forged flat tops 11.1 to 1 comp
camel hump heads with the bigger valves that I have ported to flow real nice
Roller 1.6 rockers
A pro products high rise manifold that I have machined the plenum and knife edged the runners. It is port matched to the heads.
830 holley dp feeding the beast
Isky Z-35 solid cam says it should run 3000-7500
Headmen long tube headers. (heads are ported to match them)
Msd HEI streetfire(yes i know its cheap) with a updated module and a strong ground so it stays running in the higher rpms.

Hopefully I didnt forget anything. I would hope this is putting 500 at the crank but I wouldnt cry if it was less.
When the car was running with the different cam it made power 2800 to 6800 and I was running the stock tires with the stock 3.23 gears. Was impossible to get it to hook up from a dead start. It has the 4 speed in it. When I plan on racing the stang I should have around a 255 60 tire and 4.10s in the rear. Also thinking of shooting 100-125 shot of nos. Any Ideas on what might happen? And an idea of what my car might run down the track say she stays hooked up and I get some good shifts down.

Theres not thoughts on this at all??

If you think you're putting out 500 at the crank and you can actually hook I don't see you losing.

I dont envision home ported camel hump heads supporting that kind of power. Not to mention 255/60's will not hold with 4.10s.

Not to be a **** I would take your '82 anyday sounds like a bitchen' car. But I doubt you are making 500 at the crank maybe mid 400's and I think your boss may beat you unless he can't drive.

you should invest in some wider rubber and then spray it, you won't lose on spray. Without the spray you are as good as dead imo.

buy a set of afr heads and you could change that thing into a writhing animal.

go ahead, race your boss and then beat him. then you can start looking for a new job. ;-)

I saw someone race a brand new gt500 at the track. It ran mid to upper 12's with sticky tires on the back. i will go check out the video to see exactly how fast they really are.

Those mustangs can't really get that great of a launch with the soild rear axel with wheel hop and no traction out back but once they are moving they fly so race from a dig and hope for the best

.... what does your car run in the 1/4?

There was a guy where i'm from with a 400 sb with 550 rwhp block only and a 150 shot and 4th gen rear end. We were at a car show and a gt500 rolled up and he said it wasnt even worth his time but that is with a 150 shot and the guy races turboed busa's so it would probably be a decent race. Those cars weigh so much it takes them forever to get going. let us know how it goes

I remember watching a Top Gear episode were they did numerous tests on the 09 GT 500... Even then, they (ford) stated the GT500 put down 500hp to the wheels... Well Top Gear put it on a dyno\lie detector and found it to have 447hp to the wheels... From what i've heard, since then, all they have changed is the intake; which ford states adds 40 more hp... Either way, I think it would be a good race... So do it up and let us know the outcome!!!

I had somewhere around 475-500hp on my 383 and I killed on at the track. They trap about 115mph I believe, some say as high as 118 but i havent seen it at the track. Your car should have that power depending on how well its tuned up. Your combo should have mid higher 400 hp in it, so that should be enough if the GT500 is stock

spinning isnt winning get some rubber cause he wont hook. if u can hook u should be able to take him from a dig and if he starts to creep up on u then hit the juice and leave his a**!

Those stangs are no joke....gonna be a tough race to win without juice I think. Especially with a 4 speed, don't race from a roll!!!!Theres a local guy running 11.7's with a mild bolt on one by me, and thats not hooking great either. They are fast cars....best of luck to you. Yours sounds like a monster too, so maybe you can take him if you hook.

yeah dont roll race. u got a way better chance from dig especially since he probably wont hook

Orr89RocZ

iTrader: (20)

neither car is going to hook from a dig on the street... if you have drag radials you will have a better chance to the GT's street tires if he's still running factory street tires.

Roll wouldnt be that bad but probably be a close race. Hard to say what your power is like based on ported old school heads. We have no idea what your heads flow and being an old casting design, its probably not going to make as much power as todays modern head designs with improved combustion chambers. Also not sure of your cam specs. Havent looked up the cam but its probably a decent cam duration wise to pull those rated rpms.

yeah but he plans on havin 4.10's on a 4 speed wit new tires so it probably better from a dig cause the gt 500 gears idt is as high as 4.10 but dont get me lieing to u now cause idk for sure and maybe if he keeps his 3.23 he can 70 roll him lol jk but i would def dig race wit the 4.10

4.10's on the street with new tires dont matter when we has over 450hp on motor...its going to spin hard in first. you will have to walk it out the whole until you get into second. Taller gears may actually help you out more.

At the track with prep and good tires, more gear will help that setup since it wants to rev up alittle. From a roll race, 6000 rpm in your 1 to 1 gear (4th), your doing 121mph with 28" tire which i think thats what 255/60's are. Starting from a 50 roll, thats second gear at 4000 ish rpm...gooooood spot for that car I would think. Peak torque is probably in the 4500 rpm range. Slam gas, shift when you need to and pull on him in 3rd. Take it to 6500 rpm at 100 mph and call it a day. 50-100 mph is a good roll race and should easily determine the winner.

well from a roll the gt 500 will probably pull on him wit its 6 speed and 3.55 gear. his best chance of winning is probably for the gt to blow the tires off from a dig
