Replacing the torque convertor in my 89 during trans rebuild.

You answered your own question when you said street/highway.

I just put in a stock stall converter a few days ago. No reason for a high stall converter on the street.

Watch out for "bargain" converters. My $200 unit went bad after 150 miles. Maybe the 90 day warrantee should have tipped me off (I bought it last year -- out of warrantee). It didn't fit right anyway (too much space between the converter and flex plate, but I didn't know that was a problem at the time.

Now I've got a $325 converter with a two year warrantee. I have a lot more confidence that this one will last. I'm too old to be crawling around under a car for days pulling and reinstalling transmissions (third time -- a charm, I hope).

Keep the lockup it will help with highway gas mileage (high stall converter or stock stall)

I'm running a Precision industries vigilante 3500 stall with lockup on the street with no issues......

2200 to 2400 a good range for a torque convertor for my 89?
Engine has only zz4 cam and roller rockers ..been trying to catch up with Pete K
A guy was trying to sell me a 2600 to 3200 with lockup and for street use and said this would be fine?
(online guy winnerschoicetransmissionparts ) any body purchased from him?
Not sure what OEM was?

Keep the lockup. It's like a fifth gear. I'm running a Precision Industries too. Bulletproof unit.

I was running a 2,000rpm lockup TC when my engine was building 300chp; it launched really hard on the strip and would easily blow the tires off on the street. BTW, I was running the stock 2.59s out back.

I will search around for who has a deal on between 2000 and 2400 then.

Out of curiosity if eg I actually installed something with a higher stall than necessary say at 2600-3200
would it just kick in earlier,and work the same?
