Which would be cheaper to get into the low 13 or high 12's?
a rcsb 4.8 5spd 2wd
or a rcsb 5.3 auto 2wd
the only requirement is that it stays reliable for daily use. :guns:

5.3L auto, although the tranny will not last too long at those power levels.

you could get a 5.3 n/a to 13's and upgrade or build the tranny.
