i have the oppertunity of buying a porsche 928,5speed manual in very good condition,but no motor.i have a fully reconditioned 560 and would like to know if putting this beautiful,reliable almost bulletproof mercedes motor, instead of a second hand porsche motor with the 7 foot timing belt and the headaches and costs involved with porsche in australia,can go into the 928?this would be a project over time but i am interested in hearing from anyone who has a view on this or has done similar.thankyou,peter
