hey guys, I have the option to pick up two motors for a smoking deal. one appears to be a newer 5.3 but missing a intake. Heres what I know.

Complete motor with harness/ no computer:
This was on the block 0127409006433680
heads 862
back of block 12567393
front block j051
coil L31J26/2019

2nd motor/ this is missing intake, no wiring, it was hit in front. a/c bracket broke, water pump pulley damaged. and theres a bolt broke off near oil dip stick on side of block, looks like 1/2 bolt (what is this? other block doesn't have it)
He says its a GEN IV 1297
block 12588778
head 7081W6300777
heads 243
