How can I determine what my torque converter stall should be? My 24 T coupe weighs approx 2600# and has a 265 flathead with a buick 200-4r trans. (2008 I believe) It came with the stock converter and from a dealer, unk. now. Driving this weekend I found that I had to keep heavy on the brake but keep rpm up a little to keep the engine running while coming to a stop. Have not driven many miles and always thought I had some type of carb problem making it die at the light. Any help or guidance will be greatly appreciated even if I don’t look forward to the replacement. lol The trans is fantastic by the way. Thanks in advance, Fourdy
If you can idel down your motor to very close to stock factory idel RPM,you don't need any conv. other then the stock one,but ;; Stock stall speed of cov. is set to work find with a motor that idels smooth at as built by the factory,were we get into probs is if you can not get what ever engine your using to run OK at that rpm; Often big cam with lumpy idel that is about 2x higher then stock is why the stock cov. dose not drive EZ. The weight of your car has far less to do with how it drives then rpm the motor can idel at,but weight dose have some efect/heavyer the car the less brake need,just like the less rpm the less brake needed mostly. It all adds up to ether getting your motor to idel low with a stock conv. or finding out what your min. idel is an getting a conv. with higher then that stall by something close to 300 to 500 above{ best to talk to conv. sales guys as to what to use. Bottom lines,get it to idel well at 400 or 500 RPM an it should then drive OK with only a little brake at stop*,but there is another factor an that is,if your brakes take a lot to stop the car anyway,look into fixing that.
