99% chance of 7.0L block

[number77]

427 cu.in.
7.0L
this was casted on the cts-vr engine block

from that and a inblock knock sensor it is most likey the production block. the same intake was also used on the woodward GTO. which points to a "goat"/"judge" being on the way


edit: also note the exhaust ports. :shock:




edit: word is the the next gto will have the ls7 block, this is suppost to be it.(not to be confused with the entire ls7/z06 engine)
