S spudlu120 Junior Member Mar 4, 2013 #1 I am replacing the 223 with a 390 and I am wondering about the spring spring rate. Did the 57 V8 have more spring? Thanks!

D darrell Well-known member Mar 4, 2013 #2 you will need heavier springs.the 58 had the 352 which may work.
Ford blue blood Well-known member Mar 4, 2013 #4 The 390 is not a lot heavier then the 223, put an aluminum intake on it and they should come in the same or really close.
