looking to swap a later model 235 in place of my splash 216. tips tricks? would like to keep my 3 on the tree.
For a start have a look at Tech Tips on the left side of the screen. One of the items there is engine swaps, which addresses 235s as a replacement for 216s.
Easy and a bolt in but depending on the year of the 235 there is water pump issues,55 to 62 motors have a longer water pump that is lower in the block. Shortened pumps are available and there is a adapter to mount a 54 on back pump to the 55 to 62 motor which I am using on the 57 235 in my 37,a 54 motor is a direct bolt in since it has the older water pump.
i went with the later model with the fancy oil pressure. im pretty sure it already has the smaller water pump on it. someone said it was put into a 48 plymouth way back when
