Options for Replacing Slant 6 in 65 Dart

well if your looking for a nice streeter id go with a 318 with a 904. they give alot of oomph and have very nice street manners. well mine does for now (LOL). but if your lookin for a nice street strip small block you could get a 360 with a 904. those are nice. and then theres the last option a 440 with a 727 theres ur real power lol
