Default shift points with TR224

those of you running a tr224-112, what are your shift points set to? my 1-2 and 2-3 shift is 6400 and it seems to still be pulling. just curious...

Is that with your current cam, or when you had a tr224?

I'm pretty sure I would benefit from a higher shift point, but am afraid of the stock rod bolts and what not... this motor has 136k on it

i would leave the shift points alone with a stock tranny, wait until you built the tranny then raise them up...
