88 stang 5.0 / 5 speed

I would say ls1 if you can drive but should be a close race

89IrocZ350TPI

So thats a good h/c combo hes got? Not sure what it dynoed. I would think a cammed ls1 would take one pretty easy but I dont know much about the old 5.0's

Orr89RocZ

They can be quick cuz they are light but yes its a decent heads cam combo. Both setups are low 12's capable possible high 11's

I take that back abit... Tfs stage 1 isnt as big as i remembered. Typical dyno 270-290whp and at 2800-3000 lbs they can run mid lower 12's in goood air.
Ls1 with 228r is a 380-400 whp car and should easily be mid high 11's in 3400-3500 lbs

Z28FAST1

That might of been a decent combo in the 90's but you'll make him look silly

GenX'Motorsport

^ In the 90's? What does that mean? Hp hasnt changed since then, 300HP then is still 300HP now. Scales are also the same 3000pds then is 3000lbs now.

Fox bodies can run, small bore with a short stroke in a light car. properly setup 5.0's will always be the street cars to beat. cammed only with a little boost and some gears and exhaust you have an 11 second car the hops from stop light to stop light.

This should actually be a good close race IMHO.
For the most part its gonna be a drivers race. The man that can drive the manual better and hook will prob take it.

Z28FAST1

^^^Living under a rock or have you missed the pony cars roling out of the dealers with 400hp STOCK! Pretty sure there are soccer mom minivans making more power than 300hp.

GenX'Motorsport

Chill out Jr.. All ive seen on this 1 section of TGO is you bashing everyones car, motor, combination ect... And even bashing traditional drag racing. And yea I know about new cars and the factory HP ratings. Ive also owned alot of different cars in my life, from vipers, to mustangs, M3, vettes and of course Thirdgens. And been turning wrenches before you were even a twinkle in youre daddys eye. You should really stop typing and start reading and researching. But then again, you prob wont own youre Thirdgen in 2Yr's from today anyway. So, you wanna "roll race" me? LMAO.. I just built a really slow bored over 454 ci and put it in a smart car. lol

zraffz

I seriously think you are lacking part of your brain. Go back and re-read what he said.

Anyway, that car will give you a good run for your money. Even if he only matches your power he has a huge weight advantage over a stock ls1 car.

two60two

Because 3000 pounds is lighter then 4500 pounds doesn't mean anything. This also has nothing to do with the topic

Also torque curve and peak power at a lower rpm don't mean anything. Gear ratio plays no part in anything either.

The car with more power isn't always the fastest.

zraffz

It is when you roll race like the Supras... lmao

I can testify what the same motor feels like with 600lbs less weight in the vehicle. Totally different animal.

GenX'Motorsport

I agree, wow. More like most of his brain, not part lol

Im sorry Jr.. I guess I should have said 850HP then is still 850HP now. But im pretty sure you missed the whole point.

two60two

My Taurus has beat a lot of thing on highway pulls. It wakes up around 80-90 which isn't far from where the quarter ends. People get all mad when I say it runs 15.7 in the quarter.

89IrocZ350TPI

Yeah thats right about what my car threw down on slowhawks mustang dyno with the clutch slipping.

UnstableAviator

I'm going with the car get has the "driver mod" for this one. From a roll, LS1 should pull the 5.0.

Savage388

I really dont think a mild 5.0 would outrun a 400 rwhp ls1. I know they are light but com on that thing makes like 270 at the wheels, thats a big difference right there. on top of that if its not the light lx then the weight difference is a bit less.

zraffz

I would have to agree. I didn't read his sig I just read LS1 vs h/c 88 5.0 lol.

89IrocZ350TPI

Yeah I dont think there are too many stock ls1's out there anymore. Most of them have more mods than me.

25thmustang

The LS1 car should win. A simple HCI fox would be a good run for a bolt on LS1. A cammed car should win, in my humble opinion.

The mustang would probably be closer to 300 rwhp, but I still put the LS1 ahead.

danziger

I think the 5.0 will be putting down more like 260-270rwhp with that combo and I hope the T5 stays together. Both cars will need a deft launch on street tires. The longer the race, the bigger the advantage for the LS1.

89IrocZ350TPI

I knew you were on here somewhere. I thought it would be a better race for a stockish ls1 since they usually throw down around 300 wheel but I wasnt sure. Thanks for the help.

25thmustang

My problem is I only really have experience with the cars we run. My stock cam, stock head car runs with stock LS1s (high 12s on 18" wheels, mid 12s on slicks) and my brothers mild HCI car runs with bolt on LS1s (higher 11s on a tire, we don't run it on the stock street tires). I haven't been into the local car scene other than the race track in years, and my racing friends all seem to have cars running like ours, HCI cars are 12.0 or better, stock head cars are 13.0 or better.

Here are a couple of videos of my brothers Explorer head/cam/Cobra intake fox. Not sure on rwhp, but probably just north of 300. Car weighs 3100 lbs or so. Best has been an 11.708 @ 115.39. Has some suspension work, stock T5 with a motorsport clutch, Long tubes, xpipe and mufflers, 4.10s, so all the support is there. I guess if someone just slapped a set of heads, a cam and an intake on, the car might be slower, but we have never been the group to do that.

Your ls1 car with t56 could use alot more gear tho but then traction would be alittle tougher to find

big hammer

loolz.

and the old 5.0 was a big bore-short stroke.

GenX'Motorsport

No. The GM 305's in thirdgens are "slow" because of the strok to bore ratio. CI's alone dont mean as much. One of the reasons Ford 302's are better motors.

Edit: 305's suck...

big hammer

im talking about the ford 5.0


and the 305 had more hp than the 302.... but it was restricted by a crappy induction system.

Podium

iTrader: (2)

A lot of weight? My Iroc weighs 3280 from the factory with no weight loss. 305s suck because of the small bore. The Ford 302 is a way better motor than the 305.

Z28FAST1

Didn't get updates and forgot about this thread....

What I meant was a "built" 260rwhp(h/c/i) Pony car was fast in the 90's but by today's standards its not that impressive when V6 cars are making more power. HP hasn't changed but HP standards have.

You have to be delusional if you think a 260rwhp @ 3200lbs Fox is going to be a drivers race for 400rwhp @ 3500lbs F-body.


^^^See above.




Not missing part of my brain, you just over looked his mods...


GENX, out of curiosity, what kind of numbers is your boosted car making? I'm debating going with a F1 procharger or KB.

Edit: 305's suck...

big hammer

the small bore on the 305 sucks because of it's head design. there are only two valves, one intake and one exhaust. so when you have a smaller bore with a single intake valve the valve must be smaller. this hinders airflow. the valve is also closer to the bore which hinders airflow.

the 2jz is not a direct comparison because it is of DOHC design. two intake valves. this help the smaller bore utilize more airflow at a higher rpm where hp is made.

the 305 is not a shitty engine. they can run forever. but the smaller bore is indeed a design flaw for a performance engine.

PHAT89TA

Ls1 for sure. When i was stock i raced a heads/cam 5.0 lx and he was dead even with me. definatly suprised me he held with me.

Street Lethal

iTrader: (16)

Edit: I promised myself I wasn't going to argue anymore with other members, so disregard everything that I said. Chevy's 305's suck, their bores are very detrimental in making any real power, and that is that. As for the question of who would win between the LS1 and Ford 5.0 w/heads and cam, race them and find out...

89IrocZ350TPI

I actually forgot about this thread. I got him pretty bad. It really wasnt close at all surprising.

Time for some ported ls6 heads and a new clutch

Is it to much to ask to pull out the camera and have someone get proof, not saying your lying but gratification goes a long way. Yall build it up like ohh noes and the thread blows it's load as soon as it starts.

How many buses did you get him by?

Can't believe people thought this was going to be close

ls1's are wicked titty.

ls1

89IrocZ350TPI

Started at a 35 mph roll in second. By the top of second I had a couple cars on him and I maxed third out at 115 and was ahead by about a bus id say. He said that his car put down 265rwh on a dyno jet. I was right around 400rwh on a mustang dyno. His car seemed to be running rich and its at 150,000 miles vs my healthy 35k ls1 so I think that made a huge difference.
