the motor im using is a 0 mile 69 351 shortblock i have, came with a set of jacked up cheap aluminum heads that were used and need welding and much more... got quoted 1k to fix them. not worth it. if the were not a chinese knockoff cheap head maybe but they are junk. all i currently have is a shortblock. hence needing the front dress etc from an explorer. if i get anywhere close to 350 i will be happy. in a few years if i still have the car i will probably want to put a coyote motor in it anyway so another reason not to put too much money into the 351 that would end up on a pallet in the back of the warehouse.
