I have a 64 El Camino 283 engine, power glide transmission, with what I believe is the original 10 bolt 8” rear end and I believe it has a 2.56 gear ratio, GM1, #3839390N.
I’m thinking of upgrading to 3.42 or 3.54 gear ratio and upgrading to a 700 or 200-4R transmission in the near future. The plan is to make it a daily driver on street/highway and drop in an LS1 engine at a later date.
I have 17 inch wheels, 245-45-17 I believe.
I’m a noob but I plan to upgrade the gears myself. What’s a good upgrade kit?
Would this combination be ok for now with the 283?
Would the jump from 2.56 to 3.54 be hard on the 283 with power glide?
I’ve read the 200-4R is an easier install then the 700R4.
Any corrections, suggestions or advice?
