Stall and Shift RPM Question.

1st.
Sorry for the PN on the Cam. I typed the XE268 and with the parenthesis it gave the icon. It is in fact an XE268H with the springs, rockers, and pushrods to match.

2nd.
I did not make this clear but I know now and knew then that 3000 was way to high, I used that number for illustration.

3rd.
Most important, Thanks to all for the information.
I think I need the higher stall to get the most out of my 'teen.
With that, I was concerned about the interaction between the converter with the higher stall and the A904's "Grocery Getter" low, soft shift points. With the B&M Shift Improver that is in it now, my shifts are nice and firm but under WOT, it still wants to shift out of 1st at 2800ish, just when it is starting to 'GO". I have read that the only real way to correct this is to drop the pan and either change the weights or the springs on the governor. Way above my head.

Finally, I would not go out and buy the $200 POS converter.
For some things I believe in the local Oreally's etc. for the value. But...
For other things that will require much time and energy that I do NOT want to re-do because the El-Cheapo part I bought failed, I will rely on specialist input.
With that, I am here on this forum where there is a plethora of good advice and great wisdom, (and some not) to start the needed research and learning.
Thanks to all! ').
