I have a r.e.d. 250" wheel base running in the mid 7's. I just changed my rear end gears from 4.86 to 4.29. I wanted to know if this takes too much off the bottom. If my trans first gear is from 1.76 to a 1.96 ratio with out changing every thing in the trans. input shaft, drums, or maybe 1.80 ratio.
