I decided to remove the MFI from the motor. This will allow me to make progress on modifying and rebuilding the throttle bodies, stacks and pump while continuing the sheet metal work. I found yet another mouse nest - this one is on top of the oil cooler.

The build details of my 2.5 long stroke are starting to come together. With the MFI removed from the motor, I am making decisions for the necessary MFI mods to work with the motor.
I am starting with the pump. I have spoken to Mark Jung (MFI Werks) and have agreed to ship out my pump for the following to accommodate using S or mod S cams and boring my head ports out to 36mm:
- Complete rebuild of the pump and clean and pressure test injectors
- Small fuel flow adjustments for acceleration from idle and cruise and still keep the freeway cruise @ a lean mixture
- Mid and upper fuel flow increased by 25%.
- Minor adjustments to the thermostat for cold starts till warm up.
Mark is a busy guy - I won't see my pump again for 4 or 5 months - but I am not in a rush! Here are pics of the rather dirty condition my pump is in now - let's see what it looks like when I get it back!

Question: did you delete your AC? If so any tips on removing lines, condenser, etc?
Thanks

Spent a few hours drilling out spot welds and cutting some seem welds. Good fun - not really. I am done drilling spot welds! Anyway, I was able to get much of the parcel shelf out but stopped until I can get some more input from Andy. This has been the trickiest part of the sheet metal removal for me so far.

Shipping my oil cooler to Pacific Oil Cooler today. They will ultrasonic clean, pressure test (repair as needed), bead blast and protect with iridite chromate finish. My cooler has 47 years of baked on gunk that includes melted plastic bits from a mouse nest. Let's see what it looks like when it comes back!
