My goal with this swap is a dependable power plant therefore I'll be trying to stay focused on that with minimal modifications.
Engine Mounts: Use existing DIY4X comp mounts and ORD engine crossmember
Electrical: The harness was cut so I'm leaning toward a Howell harness and PCM.
Throttle: I have an L29 throttle body from my other build so I can ditch the DBW this engine has and I'll pickup another lokar cable that attaches to my pedal setup. I read something about possibley needing throttle body spacer. Need to investigate that further.
Fuel System: Currently installed is a EP381 pump with 6an lines for the fitech so I'll just need adapters at the fuel rails.
Exhaust: Use existing big block tubualr manifolds and exhaust.
Cooling: It's all there (454 radiator and windstar fans) however I read that one of the heater hoses needs to connect to the radiator and I don't think I have that port. I use the mojave heater often so I need to figure that out.
Power Steering: Need to figure this out, I'm hoping I can use my existing sagnaw PSC pump.
I've been reading through the 8.1L resource thread and making notes about things I need to replace and address while the engine is out. I'll be ditching the EGR, oil cooler and EVAP systems. I'll pickup a new crank sensor, gasket set and a new water pump at a minimum. The oil filler neck needs to be replaced and the part is discontinued by GM (PN 12581140). Might be able to use a "straight filler neck" with the L29 throttle body? I also need to figure out an intake and filter setup.
