I have over a grand in my motor rebuild.It isnt a 383 stroker but it suits me.The block was bored,the stock crank was polished.New pistons,rings,bearings,timing chain,cam,lifters,etc etc.Stuff adds up.
Here is a link to a kit on ebay just to let you see what kind of pricing you are looking at and for what stuff.It's gonna take more then whats in the ebay auction to get you a stroker motor though...
