Please help
 

I have stroked 06 TL with a 3.7 crank in it(along with spacer machined so shorter 3.7 crank fit in stock 3.2 block) it stopped running while cruising and when I tried to turn it over it sounds like an older Honda motor when you have a broken distributor and it sounds like it turns over fast and kind of whiny anyone have any idea of where to start looking for problem(already checked to see if timing belt broke) any help greatly appreciated.
