63 5 speed transmission is as heavy as a world class t5 s10 unit!
SR20DE have read can weigh 230lbs in race trim but trail the qr20de
about 30lbs overall due to die cast alloy top and bottom.
More compact all round with better narrower head etc.

A12 and A15 engines have little difference according to your data
I measured bare A12 and A15 blocks and weight drops dramatically
when bored 3-4mm from stock like removing 2 feet steel pipe in weight.
