The P engine (and the chevy I6) actually weigh about 50% more than a SBC with iron heads.
Nissan 6: 640 pounds (Chevy inline 6 is just a few pounds lighter- about 630)
Iron head Chevy small block: 430
aluminum head Chevy: 400
regarding the springs- the perfect neutral stance for a SOA conversion is for the springs to be horizontal (zero arch) on flat ground, and for the spring rate to allow equal amounts of compression and droop travel. Any positive arch on the front springs at final ride height increases droop travel, and decreases compression travel, which results in increased likelihood of bump steer.
and this geometry should really be set with your final powertrain choice all mocked up in the vehicle
