Ok in 1987 you could get the 5.7 which had 220 hp and you could get the 5.0 with a 5 speed(mine) and get the HO cam(l98 cam??) and get 215, now wouldn't that mean that the 5.0 could keep up with if not pass teh 5.7 seeing that it is a 5speed? anyway, what did the 5.7s run then and what did teh 5.0 run then? anyone?

 

Your looking at peak HP. What about the peak torque. What about the power (hp and torque) under the curve.

Your also looking at auto Vrs standard. Sticks put more power to the pavment than autos. But still, I see where your comming from Id say if you had a 3:42posi and the 220 hp auto 350 had 3:08's or 2:73's I'd think you would probably walk all over the 350.

I have an 89 auto 350 IROC 230 advertised bhp
2.77 gears. I raced an 88 IROC 5 speed 305 don't know what his bhp rating was but He didn't stand a chance from the word go. My car is stock the only mod i've done is remove the smog pump. I'm no expert but more displacement = more torque and hp is relative to torque.

Also to add a note GM ALWAYS underrates there cars to prevent insurance and dis-satisfied customers that dyno there car at 1hp less then advertised. Also nothing could be rated over the Corvette but we all know the 89 TTA did not have 250 horse and drop a 13~ or so 1/4 mile.

Honda engines ROCK, I have one on my lawn mower but I still have to push it.

 

That is the type of stuff I hear ricers say all the time.

*****: "Your IROC has 240hp stock and my Type-R/VTech (or whatever the hell it is) has 220hp. I can beat you!"

My reply: "NO YOU CAN'T!!! While hp numbers are similar, I am putting out almost 350ft/lbs of torque vs. your 175!!! You don't stand a chance!"

Horsepower NEVER, I repeat, NEVER, tells the whole story.

Nothing against 5 speed LB9's, but I have beaten a few of them with my 89 5.7. Hey maybe they just didn't know how to drive. They all run good man 5.0's & 5.7's.

West is about right.... a properly driven 83 or 84 L69 5-speed, a LB9 5-speed (especially a S-D one) and a L98 auto all in bone stock condition all run real close to 15 flat. To compare the factory's HP & torque numbers is more than a little misleading. Those 3 setups are the fastest of the 3rd gens. They are close enough that the driver, tires, other options in the cars (weight!!!), and stuff like that could tip the balance in favor of any one of them. This is true especially if the 305 is a Camaro and the 350 is a Firebird, since on average the Pontiacs tend to be a little heavier.

Not this slightly modded MAF 350. See sig.

I have beaten modded LB9 5 speed cars with 3.73 gears with my 2.77 geared IROC. 350 Torque is KING.

stock vs. stock the 5.7 car puts out better numbers. all the way through the tests i have from the third gen years the 5.7 was about 3 tenths quicker than the 5.0 5 speed. but once again this is a waste of time question that seems to be asked about once a week if not more often. it simply provokes argument and doesn't get anywhere aside from it not being a tech question. it end's up being a prefference between having a stick and having cubic inches.

 

Ooops you for got the TTA when speaking of the fastest set up.
Oh and to all those who think the auto waste so much power... figure this one out. The TTA was almost a .5 sec faster in the 1/4 mile than the proto type TTA that had a 5-speed.
Debate that one out. I will give you a hint it has to do with boost.

Past Thirdgen:
86 Trans Am w/ built 355TPI with SLP goodies and too much other stuff to List. One sweet *** car, wish I would have had a good enough Job to pay insurance on three cars so I could keep it, but for a 89 Turbo Trans Am w/ Low miles, I think I made the right choice!

 

Here here.

 

Yes this is true, but only because with an auto there is no time delay for gear changing and the shift points were changed to help keep it in boost.

Did you ever see how fast the 5 speed TTA is on the flats? Oh my ### that thing is fast!
