Hey Leon,i use a standard small truck starter,it bolts directly to the adapter plate but has to be spaced out just a bit, the starter nose isn't supported,i have been running it like this for years with my old w8 motor also.Give Eric a call at jw,he has the flex plates and crank adapters on the shelf now,if you need one.These little motors are very reliable,we have 560 passes on it this year,and it was just a takeout motor,we didn't change anything,just bolted our rons alky injection on.The car weighs 2600 lb with her in it,shifting at 7800,it runs 5.50 at 124mph best,Thanks
