MCA, Have done many ourselves and also sold many kits to perform the heart transplant youself. Instructions come with kits. Can also provide digital pictures if needed. Alot yourself 24hrs. with two men if you have never done one.Have done a tranplant in a 10hr. day with two men who know what needs to be done.Only work with the 8.3l(505C.I.)as this engine will provide all the HP you will need,epsecially if you do some of the Hyper Mods..Have all of the engines we have installed running at 250-260HP. Used engines are easily located and if you desire new,that is also an option. E-mail me if you have further questions, Hyper Harvest II
