I have a 200 in my 65, Can a 289 be droped in with different motor mounts an not changing anything else. It has no power sterring?
yes. As long as the transmission is a 6 bolt bell housing, and not a 5, but would upgrade the transmission to a V8 tranni as well.
there are several articles in the archives about doing just that...http://www.mustangmonthly.com/techarticles/mump_090203_ford_small_v8_engine_swap/viewall.htmlps... Don't throw out anything that you remove.. its all needed by other mustang and ford six owners... you will also want to nose into this articlehttp://www.mustangmonthly.com/projectbuild/mump_0007_mustang_front_suspension_upgrade/viewall.html
