that wasn't directed at you intentionally, sorry for the confusion. and yes, the engine in the first picture is a crown vic motor. P71's looked like mustang engines with the upper intake swapped to the drivers side, like older crown vics did with the 5.0.

true, the internals are the same throughout the 2v lineup, but his first goal should be ditching the restrictive NPI heads first if he plans on keeping the stock shortblock.
