I am in the process of building a 1993 ford ranger 4x4 into a pre runner/class 2000 truck for some local races. Now onto my questions I am pulling the 4.0 out for a rebuild plus a little extra to wake it up not lookin for huge power just a little extra and I figured I might as well wile it's out and being rebuilt. Will be bored .20 or .30 over depending on what the machine shop says all new bearings ext now for my questions I will be running a comp 410 cam and I would like to run the 1.73 adjustable rockers also will I be okay with stock length push rods and valve springs or will I need to change those and if so what length and spring rate will I need to purchase.
