hello vejar. congrats on finding a new project. i suggest that you examine what you have there. before making plans on replacing the engine,check it for yourself , or have it tested by a qualified person to be sure it needs any work, that is unless you intend to modify it from stock. that vintage of jimmy motor is a good one, if it is in fact the original motor.whatever you decide to do , this forum is the place to find the answers to all of your questions. so when you get it ,touch bases here and let us know all about it. good luck.
