Hi, i have a '96 Galaxy Ghia with engine knocking, just done big end shells which had gone, but still bad noise. My question is whether the old Sierra DOHC 8V lump is the same ....... well i've been told it is the same, just don't know whether it has all the required holes drilled and tapped. If not, other ideas on easy(ish) engine change??? Cheers guys :D
