1970 Roadrunner 383 .40 over w/ 4 speed. It has the orginal 3.23 gear in it, I want to change to 3.55 or 3.73 dont want to go any further since I will take it on the highway sometimes. I'm looking for more low end performance. The 3.73 calucates to be 3135 rpms @ 70mph, the 3.55 comes in at 2984 @ 70 (this is based on 28 inch tires.
What I want to know since there isnt that big of a difference is your experience with 70 roadrunner with these different gears do you favor one over the other and why.
Thanks
