Finally get to pretend I am one of the cool kids - Holley kit swap
Got my core 5.7 setting in my '73 finally. Need the motor in so I can start cutting the floor and building a cross member for the T56 Magnum.
This is with the Holley mounts, headers and oil pan.
I used the recommended oil filter adapter, works well.
I even have room for the AC compressor.
This is a compressor from a 2012 1500 or 2500 Ram so it isn't the same as a car compressor. RockAuto shows they both use a 10SRE18C style compressor but not the same part number.
I do know that I can remove and replace them both with the engine in the car because I dropped the motor in with them bolted up and then had to remove them to knock the spool mount bolt in. Not saying it was fun, but doable. The oil filter adapter has 2 bolts that are pretty well hidden from view from the top, but going from the bottom made them easier to see and get at.
