Besides my K20 X and my 037 project, I am also working on my "Gran Torino" (movie, not car model) truck. I got it in January, and have since swapped out the straight 6 300 & C4 for a V8 351W & C6. Other modifications so far:
Aluminum manifold, Holley carb
Electric fan package adapted from Inifiti FX35 stock fans
Replaced all engine and sensor wiring with correct Ford color coded wiring
Replaced front rotors, pads, wheel bearings
Replaced outer tie rod ends
Hooker block hugger headers
Replaced entire exhaust system from head to tailpipe with my own design
Replaced instrument cluster and warning lights with full VDO Vision Gauges instrumentation, added Innovate WB a/f ratio sensors for each bank.
New sensors for all instrumentation including in-tank fuel sender
AutoMeter Sport Comp monster tach with shift light
The truck came with some restoration work done, the gas tank and brake lines look brand new. The wiring was a nightmare but I've replaced probably 50% of it so far. It's a work in progress but it will be the last truck I ever own - todays trucks are stupid expensive planned obsolesence appliances that require certified technicians to work on them. I don't need to be paying for that the rest of my life...
