was there not some 2.8s fitted with EFI tho,
easest way to tell between 2.8 and 2.9
2.8 has four exhaust ports and 2.9 has 6 exhaust ports.
they were only found in the granadas
unless someone has gone through all the effort of swapping them over that is, or even having some US spec 2.8 6 port heads shipped over
