SOME of the parts will work. 273-318 engines have different length compressor struts as the 4-bbl intake is taller making the struts shorter. When I put a crate 360 with a factory 340 intake in my 68 Dart convertible that was originally a 318 A/C car I had to modify the struts. The original parts will work but modifications are needed. As said above 70-up parts are even more different.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
