Hah, I have a couple 5.0 motors lying around...

Here's a cool article though... http://www.carcraft.com/techarticles...dup/index.html

Not to worried though, leaving my 305 bone stock expect for headers and exhaust, as well as cold-air intake. Basic stuff and all money on body and suspension. It's fast enough for me and when it's time for a rebuild a 350 fits in perfect.

Thats an interesting article, however I would think that 95% of people that built something similiar would never see that kind of power. I have built many motors, and making 405 HP out of a stock 302 with a stock cam and only AFR heads seems pretty far fetched to me. That is saying that that motor made the power that a corvette Z06 LS6 engine makes with the best head technology to date, and sequential fuel injection with one hell of a PCM. Just seems out there to me.

I also noticed that a mustang owner commented below the article saying what BS it was and how his built 351 made only 330 RWHP LOL. Guess the ford guys were a little upset with the results too haha.

It just bolts on and doesn't require any special mods really, so why would it not be a bolt on lol?
Mine made 235 WHP and 318 WTQ through an auto and 3.23's with just the superram, injectors, TB, muffler, ignition, and tune. Everything else was still stock and it was running too rich on the runs, in the mid to low 11's A/F. I suspect I'm in the 250-260 WHP range now at least which is well over 300 hp and probably knocking on the door of 400 tq. at the motor.
I only managed a 14.2 at 96 back when I dyno'd at 235, but my launches were crap.
Most of the stock cobras dyno'd mainly in the 210-220 range with 230 being the very best of them, so chances are considering how much less torque they have and a few less HP than you were making on a 14 flat run, mid 14's are correct for them most commonly.

Your stock cam has got to be holding you back big time! That thing would probably make 300+ RWHP with a better cam. Ever get back to the track with the rich issue fixed?

And even though the intake manifold "bolts on," cylinder heads bolt on too and those are def not classified as a bolt on, lol. I personally consider bolt ons to be any part added to the exterior of the motor without changing the motors stock appearance or setup.... Headers, exhaust, throttle body, air intake, etc.

budfreak1

iTrader: (7)

No, haven't gotten back to the track or dyno since I added the rest of my mods and got it retuned.
I have a brand new ZZ4 cam sitting here I'll be throwing in with ported/polished ZZ4 heads and 1.6 rollers in the near future and a airbox to feed it all with ram air. Also going to 3.42 gears and a 2400 stall.

So I own the Iroc-z and my brother owns that 5.0. We are one year apart so we are always racing and without a doubt my car always pulls off on him. He has AFR heads, Cam and lifters, all that junk and i am just running a 90 + HP hypertech chip. nothing else.

whitedevilTA

iTrader: (8)

LOL...is your brother starting in 5th gear when he races you?

Bullydawg

iTrader: (7)

I doubt it... There is no way his AFR headed 5.0 gets beat by your stock Iroc. I own both... Granted my Formula isn't close to being stock... My best friend has an 89 GT 5.0 5 Speed, and I have a 90 5.0 Auto...

My 5.0 auto feels faster than my other buddies 87 Trans Am 5.0 5 speed.

I was in my buddies 5.0 when he beat an 87-90 Iroc and an 87-89 RS... I don't know if the Iroc was a 5.7 or 5.0, but my buddy beat them pretty bad.

On the other hand, my Formula destroyed my buddies bolt on 5.0 and his stock 89 5.0 GT 5 speed, along with all the other 5.0's I have ran into where I live.

Ive lost to a h/c/i 5.0 forged pistons crank from a dig and a roll. Im lt1 so i doubt a 305 5spd would even keep up with one.

So you beat him off the line and then he passes you, Thats expected. But im guessing a geo metro would beat your brother off the line if he has no traction.

z28man350

heres something you gotta think about too id rather be running a 305 or 350 simply because they' re both more reliable at the track im not saying a 302 isnt realiable but after running at high rpms all day i would feelconfident in my 350.

I have a 5.0 HO in my 88 TBird, with a 5 speed. It's a Mustang drivetrain with a few minor bolt ons. I can tell you that car feels faster then other stock Thirdgens I have driven, aside from my TTA. I haven't driven any 350 powered Thirdgens though. It is a heck of alot cheaper to make power with it too. Simple bolt ons net some nice gains. I had a beautiful red Iroc Z convertible pull up on me and wanted to race, and he was plenty surprised that he got beat by a piece of junk. I know it's no comparison as the convertibles came with the lower horsepower 305, but it was still memorable.

Feeling and being faster are two different things...this cars are slugs lol.

82tarecaro

iTrader: (4)

It's not stock. I swapped in a HO motor, along with a 5 speed, and a 3:55 rear. It has 2.5 inch exhaust, flowmasters, aftermarket headers, Cobra intake, etc., etc. It was a slug before that.

I think I have owned enough cars to know when something can get out of its own way LOL! It's definitely alot of fun to drive.

Bullydawg

iTrader: (7)

Any head work done to your Thunderbird? Because if not, I foresee it being a 14 second car. In which case, I don't think is too fast.

But in the comparison with thirdgens, you would have to run into a 350 car to have a close race. So I can see it being fast in that manner.

82tarecaro

iTrader: (4)

Yeah - it's not an LS killer, but I would think I could give a stock 350 Thirdgen a run for it's money. It's my daily driver beater. I use it to get to work around the mean streets of NYC. I am constantly changing front end parts because of the terrible roads over here. The rims are bent, and the car is a dented mess. But the 5.0 is one of the most reliable motors I have ever owned. It's probably a 14 second car like you said. But I am only comparing it to most stock thirdgens. It's definitely faster. But you are right. A set of heads would really wake it up. If it makes it ten more years till I retire, I am going to build it the way it deserves to be built. I figure it earned that.

whitedevilTA

A 5.0 will respond no better to mods than a 350 TPI...it's just that the ford 5.0's have way more interest and much more of an aftermarket than a TPI motor does so any ford guy can open a magazine and do a bunch of bolt ons and notice a gain. We can't even buy an aftermarket cold air intake so a lot of the mods we do are owners that know thier stuff and can fabricate. Bolt a holley stealth ram to an otherwise stock 350 TPI and you have a mustang 5.0 killer. Both great motors, but TPI engines are very looked down upon for no reason. They can make decent power if you know what your doing.

well i have not in to the motor at all weather someone else did before i got the car who knows all i have done to it is 3 inch flowmaster muffler system a chip from tbi chip stage 1 msd cap rotor coil 4 inch open element air cleaner with top lid a 4th gen rearend swap to 3.43 posi disk.

ya your prolly right the back of the mtor does show 5.0 on it i got a lt1 cam i wanna put in it to soon if i can get 300hp out of the crank i would be fine with that and 330 crank tq i would be fine with that to just give me enough hp to kill gt mustang thats are a lil big modded not cams spuerchargers and stuff like that

Lets keep this on topic. Make your own thread about how bad *** your 305 TBI car is.

Anyone have any Stock for Stock races against mustangs? I personally have never lost to a mustang yet.

whitedevilTA

iTrader: (8)

No really stock...but I wooped up on a bolt on new edge GT with my old motor. It was a cammed/bolt on 305 TPI with a 5 speed. Made 235 RWHP. This guy pulled up next to me while cruising and was pacing me. When he saw me look over, I heard the downshift, so I followed suite and he jumped on me. Reeled him back in and then put about a car length on him before we shut down. Dude wouldn't even get back beside me after that lol. It was the first new edge I had ever raced with my cammed combo and I was a pretty happy camper!

5.0 chevy > 5.0 ford

Stat wises supposedlythe IROCS 350 anyway edged out the 5.0s back in the 80s. I owned a few GTs back in the late 80s. Laid waste to many an IROC, Vettes were tougher as they usually had a better gear and lighter. Fun nonetheless but looking back they were all pigs.

Drove a mint 86 5.0 I was going to buy months ago and couldnt believe how slow it felt even with 3.73 gears. When youre young about anything feels fast. lol Now a 12 sec car feels slow.

If I could get off the line ok it was done but very very close. Most times the TPI cars could get the jump...their win.

Didnt matter most back then were just happy to see a production car with over 200hp and going up almost every yr. HP died in 70/71 so a 14 sec car was something to get excited about.

I did drive one IROC I was impressed with, an almost new 89 that was a Hawaii car, 5 spd with the 350. That car would spin in 2nd no matter what you did.
Strong runner!

Kevin Lee 487

Not to call you out or anything, but 350 Camaros didn't come with 5 speeds.

cuisinartvette

Youre right they didnt.
I did look at one that was a Hawaii car to buy that did have the 350/5spd combo, non 49 state car. It would waste the tires clear into 3rd gear. Beautiful car.

Unfortunately it was an insurance job and drove funny. Nicest IROC Ive seen to this day.

It must have been the only one made.

I didnt look at the RPOs in those days didnt even know what one was.
It was definitely the 350 that was easy enough to verify. Car was only 2 yrs old at the time.
