1980 L48 with 350 auto

I am ordering my 200R4 today and have a couple of questions:

1800 or 2200 stall?? which one?

BowTie says my stock Corvette with Th350 came with a 2200 and not the 1800? I thought stock was 1800.


I just like to cruise around with a few jumps from a stop light every now and then.

Quesiton:

What is the difference performance wise and how would they feel different?

Thanks for any advice

1800 or 2200 are both fairly stock like.. You won't notice the difference.
2200 is a very mild street stall speed...

going to buy my 200r4 real soon

Is there a difference engine wise between a 2200 and 1800.

If my car now has an 1800 and I put a 2200 in will I need to adjust anything?

My car ran real good with the 350 1800 stall but I just did not like the high RPMs on the highway. So I want to keep it the same as possible.

So will I screw things up with the 2200??

I went with the 2200 to 2400 stall when I did my conversion. I did notice the difference and it was very positive. I think the torque curve on my L81 is pretty similar to your L48 as well.

Remember, too, that you should get a converter with a lock up as well. Won't make any difference doown low, but it'll help with the fuel economy when cruising.

GrandSportC3

No, you will not need to do any adjustments... You will just experience slightly better acceleration with the bigger converter..

I have a 800 HP 200R4 for sale...

Wow if your 200R4 will give me an extra 800HP I will buy it

Sorry couldn't help it.....

Darrel1

GrandSPort thanks for the reply. I think I will go with the 2200.

Your 800hp 200R4 is a bit more than I need for my little L48 pumping out a wopping 190hp.

Thanks for the offer

I did the Bowtie 2004R conversion on my 79 winter of 2005. Just email me if you need some help.

I'll be needing help in the fall...you any good at writing papers? Did you take lots of pics?

Oliver, I thought you just put that tranny IN the car a year ago....why you selling??

marshrat99

The install was pretty much straight forward and went without any hitchs. It went so quick that I didn't stop to take pics. In fact if I didn't like quality garage time so much and a few brewskies, I'd had the TH350 out and the 2004R back in the same weekend. BTO provides very detailed instructions and great conversion kits for the shifter and TV cable.

GrandSportC3

Well, the tranny was in the car for 2 years now..

The reason that I'm selling is that my new engine (+ Nitrous) will be about 950 - 1000 HP and the tranny is only rated 800 HP.. Therefore, I need a Glide..

Are you saying that a Powerglide transmission is stronger, or can be built stronger, than a 200-4R?

GrandSportC3

Absolutely.. Powerglides can be built to 3000 HP.. TH200R4's can be built to 800 HP and might hold up to 1000 HP max...
TH400's can be built to about 2000 HP and TH350's to about 1000 HP...

I did a write up on my 200-4r install for the UK Vette club which you can have if you want (pm me your email address). You'll need to do some heavy editing to remove the cynical, twisted, bitter sarcasm that passes as humour, but most stuff is in there.

BTO told me that a late C3 has an 1800 stall converter as standard. I fitted a 2200 rpm one & the only time I notice a difference is when I step on the loud pedal harder than normal.

Durango_Boy

PM sent. Thanks.

BowTie told me yesterday that the stock torque convertor was 2200 for 1980. I thought it was 1800. Can anyone confirm please?

So if I understand this correctly with a 1800 stall when cruising I will have quicker vehicle response. If I go with a 2200 then I need to push farther on the pedal to get the RPMs up for the vehicle to respond- correct??

So with a 3.08 rearend and 190 hp- it seems like I should go with the 1800?? Is my thought process right

From my experience, no! During normal driving I haven't noticed that I need to give it any more throttle to pull away, gently accelerate, etc. The times I have noticed the higher stall rating is when I was parked in soft sand facing up a hill (the revs started cimbing more than normal before the car moved) & when I stomp on the throttle from a standing start. With a higher stall speed the engine revs can climb before the engine get's "loaded" down by the weight/resistance of the car (just like slipping a manual clutch to get the revs up into the power band). I reckon a 2200 stall converter works great in mine (2.87 rear, so maybe the revs need to get up a bit more than with a lower rear ratio).
I don't know what the stock stall speed was/is. All I've got to go on is what BTO told me (1800) when I bought my 200-4r. All I know for sure is that I'm glad I took the 2200 converter. It's fine for pottering along in traffic & lets the revs climb a bit when playing (with max torque of the late C3's being somewhere close to 2000rpm, it makes sense to fit a converter that gets the revs into that region if the throttle is floored).
