I have a 1978/79 Chevy v6 200 from a Malibu. Was wondering how many changes there are between that block and a newer 4.3. Its for a 1977 MG project I’m working on. I understand every project Definitely has its obstacles. More curious of engine mounts are the same or if I need to build new ones? Any feedback on knowledge between the two blocks or obstacles that I may come across would be greatly appreciated. Thanks
