    Hello, was wondering if anyone could point me in the direction if a good converter I've been looking at the one my trans company recommended but it says for lt1 engines can I use this on my gen 1 small block also what stall speed should I be looking to run in a stock 260HP 350 with headers, hei, 75cc smoggers and 2.73-3.08(pontiac 10 bolt)factory rear end and a holley carb stock cam with the crate and the trans is a th400 the car is my daily driver and streetabality is my main concern but not necessarily economy if that makes sense? Thanks!

    With your setup I would recommend a convertor with a stock stall speed.

    How heavy is your car ? How big are your tires ?

    Get your head around torque converters and K-factors first, if not because it might give you a better insight into your envisaged set-up, then because it's fascinating stuff and the reason why the torque converter is a thing of beauty.

  8. Stock converter..for a T350.
    Little late now, but what was wrong with the 326 for a daily driver?

    I agree with 1930 A. If you had a turbo installed I would definitely use a stall converter so you can spool up your turbo. You don't have any serious horse power being put to the rear wheels where the stall would make a big difference. I would go with the stock converter. I had a turbo in my 4.3L Sonoma. The turbo didn't get spooled up until about a second or so after I was off the starting line. The 3,000 stall really helped in my case. BTW I was putting out about 400 hp under the hood on a 3,4oo lb truck. You will have a nice daily driver with the setup you have.
  10. I'm sure you meant to say a high stall converter.
