well put it this way.... i trust paul with building this engine correctly the way he see's fit.... he knows that if the block cracks he will be getting a bad rep... and both me and him know he doesnt want that. for instance look at how fussy hes been with the head. he didnt want it leaving till it was spot on due to the fact of it was his rep that would turn to shit otherwise. but i left it all upto him so it was his choice to do.
