honestly if your hard parts block crank and heads are still good it would be cheaper to just buy a crank and rebuild kit and have your local machine shop do the nessesary work to freshen everything up and put it together for ya. new cam and valve train and whatnot would probably run you less and get more performance than a crate would for the same price. granted the crate route is less headaches sometimes but at least you get the best motor for your pricerange from the machine shop
