Did any 350 TPI (L98) cars ever come with a Manual Transmission??

[Chuck]

Someone said there were no 3rd gens made with a 350 engine and 5-speed trans. True? If so, why?

[RB83L69]

Yes it is true.

None of us that I know of were there at the time the decision is made, so we don't know for sure. But 2 likely causes were warranty / reliability issues, and difficulties with emissions certification.

[Apeiron]

It's true, but just watch someone come along and deny it. Some people say that it was because GM couldn't warranty the T-5 behind the torque of the 350. More likely it was because they couldn't emissions-certify it.

[MrDude_1]

the closest guess we have is that since the T5 was rated so low for TQ, and a abusive person with a 305 could easily break it, with a 350 in front of it, esp with how torquey the TPI350 was, it would cause reliability issues

so rather then make them and have them break, they made all 350s autos

[Scania]

I tought you could get 1LE with 350 and manual.

[91zconvt]

I still think it's because it would of made the 3rd gen as fast as a vette at the time, and we all know GM would never let that happen...

[madmax]

And of course there are always those that 'thought' you could do it, even though none are known to exist in any form.

You want a 350 and a T-5? Go get a car with a T-5 and put a 350 in it.

On paper, that can GM will never let it happen... but remember the L69? 10hp less than the vette. The TTA? 10hp less than the vette.

Both were obviously faster than the vettes of the same year... much faster. The L69 murdered the Corvette in almost every category except maybe handling, but it killed it in every speed related category. The TTA could run low 13's stock. The vette never did untill the LS1 came out. Enough said.

I think GM never put the 5 speed behind the 350 because of emitions as well.

If it was a durability issue, it never would have been behind the 305 either.

I did that.

The Vette got a six speed manual but I really like Porsche's idea of a Tiptronic for those leaning towards autos but maximizing the control the manual offers.
I prefer autos for simplicity and having an arm and leg free (or not) I do tend to do things in the car...like eat or drink that shifting makes a challenge.
I always felt the 350 with auto was a safety concern but also because of insurance on F cars (my belief)
They felt the bigger block was watered down for the audience the car catered to, unlike the Vette that is more mature and upscale. Cadillac suffered in the same regard due to the stereotype of owners but I've found Cadillac sales people to be awesome...they really get to know the customer, at least in my case...even when only going for parts. I've had a pleasant experience ...for them the performance issue HAD to be addressed for a marque getting long in the tooth but once considered The World Standard

So a 1988 camaro with 350 tpi is faster than the 1988 corvette??

I'm sure that's what it was. The TPI cars didn't get a 5spd until 87, 2 years after its debut.

I broke the 5spd in my L69 car a couple of times, even a World Class once.

Have to remember, the only manual trans for the 350 in the '80's was a T10(Doug Nash enhanced) and the ZF 6spd. Those were plenty strong enough to handle the torque of the 350.

I found a car with a 350 in it and added the T5.

I got the point of your post but just wanted to remind you of the big block vettes in the mid sixties. I believe the 66 w/ the 427 ran a very low 13 sec e.t.

Oh i know, but I was just referring to the '84+ Corvettes because that was about when it became embarassingly obvious that the F-body cars were faster than the Corvette.

Just for the record... the '66-70 Big block cars (427 and 454) ran high 12's with only slicks. In stock trim they ran in the 14's, but thats because of the garbage bias-ply tires they came with.

No, we are talking pre TPI. The L69 was a 305 carbed engine. An 88 Vette would beat an 88 Camaro.

[Scania]

Ohh sorry . Thanks for the answer

[bigals87z28]

ok, if they couldnt put the t-5 behind the 350, why did they put it behind the 305 wiht the l98 cam that made MORE POWER!! the 305 with teh l98 cam made a little less power then its bigger bore brother.
T-5 in a 350 would of been nice if it was a little stronger.

And im sure that there were LT1 6spd vettes running low 13's since they run mid to high 12's witha 6spd ls1.

What about the Doug Nash 4+3?

That's why I said Doug Nash enhanced. It was a Borg Warner T10 with an overdrive unit attached.

Warranting that trans made Doug Nash go out of business. Had to sell the 4+1 to Richmond to break even. Then closed the doors.

.

Oh I thought it was it's own tranny, not a modified T10. I've never seen one out of the car.

Yeah that tranny had its share of problems. Most guys I know with Vettes that had the 4+3 have swapped it.

I'd say the approx. 15 more HP and almost 50 more ft./lbs. of TQ had something to do with it. A T-5 will NOT last behind a 350 TPI that is driven aggressively, they barely handle the better 305s and sometimes even don't.

It really depends on how you drive. My T-5 is living quite nicely behind my 350, but I don't abuse it.

I should have worded my reply better. I'm more or less agreeing with you.

[bozbot]

I have a 350/5 speed...and i didnt have to put it in :-)
The credit for that goes to the previous owner.

that still doesnt explain to me why the 305 5spd got the more agressive cam when the auto got the crap if the auto could hold more? just doesnt seem right to me. I think a 5spd in the 190hp 305 would of made it feel faster!! Then there is the whole thing that why did GM continue to make the 305 at all after they 350 came back? And why so many variations? Should of been 350 TPI, 305 TPI and the 6cyl IMO.

They did that throughout the 80's. Like in 85 you could get the Iron duke, V6, LG4, L69 and LB9.
I guess the auto version of the LB9 got the weaker cam because the 5-speed version was considered the high performance version so they gave it all the goodies.

[IROCZTWENTYGR8]

Yeah. The 5-Speed LB9 was more of an enthusiats 305 I guess you could say. The Third Gen and the Gens before it were about choices and that was 1 of the things that made them so successful.

[camarodude91]

As for the cam choose manual cars allows had a better cam than autos. As for the Vette vs Camaro the Camaro was know to be fast form 67 to 73 exepct the 427 Vettes. After smog regulations the camaro couldn't keep up until the third gens. The early vette only had an additional 10 hp because of their better flowing exhuast manifolds and GM's need for the Corvette to have the most power.

[DanS]

I swear I read somewhere that GM sold a very very limited number of the 1LE's with a 350 5spd combo. Have to see if can remember where I read it...
