Would you change rear gear?

[Sawlog]

I just put my new motor in my 69 c10. A also put a 2000 stall in.
My plan was to change the rear 3.07 gear to 3.42 with posi next.
With the new motor and stall, I can now honestly smoke my one wheel peal from a 20 mile an hour roll all the way into 2nd gear. My old set up would fall on its face.
So.. now I'm not sure I need to change gears. It doesn't sound like I need much help on the low end like I thought I would. What do you think?
