I have a 96 Formula Z 583 that is in rough shape but seems to run alright. I picked up a 98 MXZ with no engine for $150 that looks real good and want to swap it over. I know the Form Z is an F series and the mxz is an S series frame but not sure what it will mean for an engine swap. Is it worth swap or do i spend a little more and fix the formula z???
