I've seen many stock 4L60Es go 10s of thousands of miles with ~3500 stall TCs.

4L60E is a pretty good stock OD trans, IMO.

 

There are trade-offs in everything you do. Personally in the last year I sold all my old mopars (72 Challenger, 72 Cuda, 69 Charger) in order to free up some additional investment money & buy a more practical car (99 WS6). It is all about what you can afford, put time into & enjoy based on your current situation. About the pure stocks, they are not good representation on what a stock car back in the day could do. They are however a good representation of what a pile of stock parts, a machine shop (as long as your not going for extra cubes, rules do not allow this), some ingenuity & alot of good tuning on the fly is capable of. Here is a quick video of bob k's 70 Hemi Cuda vs. (I cant remember the guys name's) ZL1 camaro

There good transmissions no doubt about it, but they cant handle near the same amount of torque the 350s can....but just think of this, why do most Ls1 drag cars have turbo 350 or 400s in them?? haha

but i wouldnt mind having another gear in my tranny to spare some gas mileage lol

 

I saw those races, amazing the potential 40 year old technology can do with very little changes to it.

 

I agree that the TH350/400 is better suited to high HP drag racing appications than a 4L60E. But the OD is nice for a street car. And at stock/bolt-on level, the 4L60E is pretty good. They can be built to handle some pretty serious power if you so desire. Places like www.finishlinetrans.com build a great 4L60E.

 

No factory Street Mopar ever made 489 HP at the Wheels HEMI included.
No stock Tune ? Carbs can be upjetted and distributors can be recurved. And Factory tunes are far from optimal on any Car.

 

Yea with those Pure stock cars, theyre certain rule about rebuilding the engine, there allowed higher ramp cams, but no over boring, stock carbs that can be jetted higher and distributors that you can recurve, but even with those little changes there able to break into the low 11s, i havent seen any ls1 camaros break into low 11s with just a cam swap and nothing more on stock tires.

and all in all old school costs less to make more power...its just there drivablility is really crappy lol

 

That's not really a stock motor then.

That's like taking an LS1, putting in a bigger cam, bigger injectors, and doing a custom PCM tune.

Not "stock" at all, IMO.

 

LMAO at this thread...To this day, the fastest pure stocker that Hot Rod Magazine tested (in 1970), was a 428CJ Mach 1. It ran 13.56 show room stock. I just saw (2 weeks ago) on the Speed Channel, a test of 6 of the fastest muscle cars made (yes, even a Hemi), and only 2 broke into the 13's, and none could stop! Only the full-on-race ZL1 cars and Hemi's of the same ilk, can run anything resembling 11's...and that's un-corked, slicks, and with suspension mods.

 

I never said Oldschool cars were slow I can appreciate all these Cars but don't throw BS numbers that were not possible back in the day
L88 Vettes are few and far between they probably made 600 HP but running low 11's On a Bias ply seems hard to believe Biasply slick thats another thing though Again a factory Street Mopar that hits 10's NOT possible. Race Hemi Maybe but Race Hemi and street Hemi is 2 different set ups

 

Last I seen Pure stock drag cars had to have the factory Camshaft and had to pass a Manifold vaccumn test aswell.

 

Those arent BS numbers HotRod mad held the event and 1 corvette went 11s in "somewhat" of a stock trim, it had dual holley 650s which were available on L88 vettes, and yes your correct it wasnt on bias, it went low 13s high 12s spinning mid track with bias tires, Mikeys were used to make the 11 second run

 

"Somewhat" is a broad term. There are LS1 4th gens running 11s in "somewhat" stock trim as well.

 

Thats true but theres no point in having power if you cant get it to the ground, The quickest F.A.S.T. car right now is a '68 L88 Vette, first FAST car in the 10's.....He went a 1.68 60ft on Bias Plys...... i dont know how you do that...

 

The previous owner of my car did his mods with the assumption the 4L60E would hold up. After dyno tuning the torque management out it started to slip and a few nitrous passes later catastrophic failure! So you can defnitely get one to fail with abuse, which is one of the reasons they have torque management. But nothing a built 4L60E won't fix!

 

The 69 ZL-1 Vette actually clicked off a 10.89 bone stock except for M & H dragmaster slicks.

 

Yes sir but like every car, add slicks knock off 1 second high 12s is what there capapble of with those crappy bias ply tires.

 

I bet you are a closet Honda owner arent you?

 

I agree, I don't know about the challenger weighing 3500lbs more like 3900!

Correct me if Im wrong but the 440ci stock HP would 375 and the 440 6- pack is 395

 

I'll just illustrate my reply. lol

1971 Chevrolet C10 327/manual
1996 Chevrolet Silverado Lift/Superswampers
1999 Pontiac Grand Prix GT--the wife's
2001 Camaro Z28 M6

Doesn't get much more American than that.
