After having to sell my 74, I have chosen a 71 to replace it. The 71 isn't mine yet, but a buddy owns it and is holding it for me for a few months (yeah, I owe him!). I'm on the road 75% of the time with most of my off road coming via sand dunes. I drive to and from each rec area, no trailer for me. I like to run around 70 on the highway which, as you'll see below, should net me around 2275 RPMs.
It has a blown 302 (runs but knocks hard in the lower), 3 speed, d20 with stock axles (drums on both d30 and 9") with 3.50 gears.
To replace the factoryoptions I have a 95 351w (5.8) from an f150, a 4r70w 4x4 tranny, and a disk brake d44 front axle. I just grabbed the engine and tranny over the weekend.
My driveline thought is to run the 351w, 4r70w, np205, d44 & 9" with 4.56 gears, and 33" tires. Thoughts? What shifter options are the best for the 4r70w (floor shift, didn't fall in love with the ratchet shifter I used in a TJ build but didn't hate it either).
351w plan: rebuild .030 over with gt40 heads, headers , efi (still reviewing intake options), serp setup, and true duals with X-over pipe.
4r70w plan: have rebuilt to stock, run the USQ1 controller and HPF1 wiring harness.
NP 205 plan: replace seals and run it, twin-stick it.
This thread is my way of planning so please share thoughts or just read along. This build will take a long time as I'm planning to build a house and a 68 Bel Air (daughter just has to have it).
