Block?
also if u get a 6.0 iron block id just bore it to 408ci or larger
i myself am doing a 347 aluminum block i only want 800-900rw at the very max
also that t76 turbo might be kinda small for a 6.0 (370)or 408 iron block. the T76 is perfect for a 347 (im running a gt42-76 its a 76 mm turbo but i got mine with a T6 exhuast housing) for ur application id run something in the 85-95mm range. most guys on here running the iron block will run an 88mm turbo also some nice 95 and 96mm turbos but those might be a little extremme specially if u plan to run 9s
