second that, im pretty sure the only time they ever changed the 308 block casting (besides the 304 size decrease) was in the vt, and all they changed was they made the lifter bores longer for roller lifters.
therefore almost everything is interchangeable if im correct
I know some crankshafts use a different rear main seal, other than that, zip.
(anyone that knows other wise please let us know, i would like to know too)
so if you use a block with a early engine number the injection all bolts straight up, and you will not have to (well "should not"... talk to your engineer) do any emissions stuff for engineering as you engine was manufactured before it was mandatory....
