One of my richer friends dad just bought him a '83 mustang gt 5.0 ho. They then got a x-pipe dual exhaust system and got the engine rebuilt. My friend and his dad both say it has almost 350 hp to the wheels.

Could this be true? Or are they taking some sort of illegal substance like I think they are?

 

Wrong. the 1985 5.0 4-bbl had 175 hp @ 4200 rpm, and 245 tq @2400 rpm.
That car probibaly has 170rwhp with those mods, provided it's in a good state of tune.

Rebuilt with what?

 

Exactly. To answer your question, yes it could be true...

 

Could be a 16 second car, or an 11 second car. Go for a ride.

 

If it's not a stock type "freshining up" rebuild, all bets are off. Add some hi comp pistons, alum heads, lumpy cam, proper carb......etc.....you could easily have 350rwhp

 

 

Yes it actually made 352.8 rwhp, but 350 is easier for them to say!

 

350 RWHP is pretty hard to make out of a 302 without being quite obvious. many guys make those numbers with 331's/347's but they are kinda obviously rowdy.

Id say they are tools and its a stock junky 302...pre-5.0 HO era.

 

Yeah 350 rwhp is tough with a stock cam. Know a few guys who have done it... but they arent backyard guys who call the motor "rebuilt"!

 

Hey 25thmustang you have stock heads and cam, what kind of numbers are you putting out? just curious. I see so many mustangs with heads/cam combos that aren't even close to your times, you must be a serious driver!

 

Stock heads with larger valves and a valve job, otherwise untouched, stock cam, stock bottem end, unported Cobra intake and all the little bolt ons. Car puts down 265 rwhp now, and 272 rwhp a while back on a honed looser bottem end! A lot of guys out there cant tune, or drive these cars which is some of the reason for it!

 

he's just getting a $300 dollar rebuild job. His dad said the place called him and asked if they could port it out a bit to help clean it up a bit or something for free and that it would add 50 horsepower when they do it. I think thier full crap cause when i took a ride it seemed fast but not much faster than my lg4 dog.

 

FYI 85s had 210 hp. 83/84s are the 175hp cars.

The car in question is an 83 NOT an 85, and an 83 would make a good deal less power. Porting ANY stock heads wont come close to 50 hp. Porting and all kinds of good parts on an E7 head, could net you 50 extra hp, but my guess is this car is about 200 hp tops.

 

Definitely never know what someone's definition of "rebuild" might be...You can go fast with stock parts, but you have to have a pretty good idea what you're doing and there aren't very many people out there with that kind of knowledge. 350 rwhp definitely IS NOT happening with energy crisis era heads...ask what kind of heads he has.

 

Race him and let us know! Seen and read about a lot of 302 performance engines and to get 350 hp out of them well you should see some AFR heads, Vic Jr. intake, really big carb! An a nice Lopey hit to it.

 

here is a quick way to tell since most people suck at life anyway..

Ask him to pop the hood if the heads/exhaust and intake look like they are worth more than the rest of the car. Then, I would say your getting your *** kicked..

If not race his stupid ***

 

I would race him but he doesn't get his license till January. Also i asked him some more questions and he said the place bored the engine like .060" over, polished it, and bored the intake or something. He also got a tune up on the car. The rest of the car is stock except his dad being paranoid got new tie rods, brakes, ball joints, and crap like that along with his exhaust system. It does have posi though not sure what gears. I'm starting to think he might of confused the horsepower with torque or it's flywheel/crank horsepower.

 

Probably got port matching for the intake and cyl heads. But like others have said, that on stock heads and cam will not push a 170hp anywhere near 250rwhp, let alone 350rwhp.

 

60 over on a stock block... Polishing it? Boring the intake, this guy is a dumb$hit who has NO idea what hes talking about!

Probably 200 hp!

And DONT run him if he just got his license. Your both going to crash and die!

 

yeah man dont race him.. ahh just a bad idea.. and foxbodies never really did exceptionally well in the handling dept. So yeah.. he is bullshitting

 

Yep kids behind any kind of power don't mix! I know from personal F***UP's!

 

Well i guess will compare time slips when highschool drags come up. Anyways im sure i'll win cause im getting many more upgrades before he can even drive.

 

haha porting and getting 50hp. who in the hell would say "im going to give you 50 hp for free"? race him from a dig and embarass him

 

That's too cool! I wish we had that sort of thing when I was coming up!

 

I'd have to agree wholeheartedly.

Most strong running 302/306's have a goal of 300rwhp, and most of the ones that get it, do so by aftermarket heads, better camshaft, and good tuning.

You AIN'T getting 350RWHP from an '83 302 with a $300 "rebuild" and FREE "port" work on the "pre HO, non E7" cylinder heads...or any other heads for that matter. (heck,the 82-84 cylinder heads were originally designed for marine applications)

FWIW, like said above, GOOD portwork on decent parts can easily add 50hp, but I'd guess the guy's still easily 150 rwhp off of his GUESStimate, considering the parts he's alledgedly using...

 

i put 3 and a half cars on a 84 302 in my stock split port stang (99-04 6ers) i put about 3 cars on the stang with my stock 305, do the math

also he is not getting anywhere near 350rwhp, one of my buddies off mustang forums has what we believed as bored .030 a cam and heads and is making 270 rwhp and hes fuel injected, he is full of it

 

Lol he says he's willing to show me the dyno sheet. Yet whenever i ask to see it he always goes "i can't seem to find it, i think it's still in the car and my dad has the keys" then we'll go to school and he'll brag about his car some more and how he has a set of keys to the car.

 

What a winner, doesn't high school rule! Just start a rumor that you raced and annihlated him, if that doesn't call him out nothing will.

 

Thats exactly how high school works! An thats what you should do start talking about how you beat him then he will have no choice but to redeem his school cred!

 

We'll he can't even drive yet so starting a rumor out of the question or will make him seem cooler cause he raced without his license. Anyways i'll let you know how it turned out.

 

You can also just call him out right front of his friends...Tell him you'll be waiting for him to get his license...

 

yeah me and two of my friends which are also his friends kept trying to get him to prove it too us but he hasn't so i think he was just trying to scare us.

 

Its HS, everyone has a fast car with NO proof! Just let it be, let him think he's the man and beat him at the HS drags if they have them near you!

 

Yes, my bad I ment to type -1983-

 

People like this guy with the Mustang annoy me to no end. Particularly the ones who's parents bought their car for them. The same stuff happens at my school all the time. I guess these kinds of people are at every highschool.

And most of them seem to drive Mustangs

 

fixed it for you

 

You could get an award for being stupid

 

I like this guy

 

get time slips you can make a dyno read whatever you want

 

we got a stock shortblock 5.0 with heads/cam/intake manifold doing 10.7-10.8's.

the guy has been 13's in a bone stock LX

 

You mean this guy?

 

idk, he goes by the name of Pure Stock on our local forum and races at pittsburgh raceway or cecil

 

10s on a stock short block is tough, but has been done many times before. Hey even my friend went 9.9 on a 308 (stock crank and rods), HCI car and a little 175 shot. Car runs 10s all day long off the bottle as well!

We have an 86 GT were gonna throw untouched E7s on a stock 86 bottem end (stock cam, stock intake, stock TB, MAF etc...), and only 3.55s and it should go into the 12s when all is said and done. Be a nice daily driver/abusing car for the family when its done!

 

I should bring the Saleen by and show this kid what a honest 400RWHP acutally feels like.

My experience is that (not you) younger kids have no real life experience on what HP really is. They graduate from a 100hp front drive crap box and then step into a 200 RWHP car and to them it fells like 1k HP.

I remeber when 14 second cars felt fast to me. "Wow, that thing pulls hard". then once you step it up and run 13s 12s 11s etc a 14 second car just feels slow.

BTW I'm going to try and hit that Sonic agian a few times this year. That little cruise spot attracts some sweet **** cars.

What exactly do you mean by that?
Are you trying to say that Thirdgens aren't "muscle cars"? If so, I'm not disagreeing. Did you think I was refering to you and your Mustang? Because I wasn't, I was talking about the kid in the original post. By the way, I'd think that someone with a Mustang posting on a site for Camaros and Firebirds would expect to have their car ragged on a little bit.


And enlighten me please, how does this make me stupid?

 

I have friend and co-worker (same guy), that has a 1993 with the 302/5spd. Stock block, rotating assembly, E-303 cam, stock heads, Cobra intake, and tuning. I was there when he did most of the mods. It has made nearly 245 RWHP on the Mustang dyno (was there) and runs 9.30s in the 1/8th (I was there and have even driven it). It is tough to launch due to the 3.73s, even with massively wide tires. If it wasn't his daily driver he would go with some Mickey Thompson ET Streets. A different coworker has a 1973 Corvette running a 150 shot with the ET Streets and it hooks without any drama, unlike the Mustang.

EDIT- TYPO it was an 8.3

 

With a Cobra intake, TB, CAI and exhuats I went 13.0 @ 103 (on ET Streets). Never ran it on street tires but a 9.3 is only a mid to low 14, and Im pretty sure the car should be a lot faster than that (I only made 221/276 with my set up that went 13.0)!

 

That would be him. http://bbs.hardcore50.com/vbulletin/...ad.php?t=36959

Just giving you hell.
