ok so my next round of mods on the 98 will either be:
pi cams/pullies or
pullies and headers or
pullies and a electric water pump..
car already has a bassani header back, 4.10's pi intake, a cai and a custom sct tune..
which is the best money per hp for these 4.6's?

Had a 96 w/o PI and now a 04 w/ PI and for the cash it is the best investment, do the swap.
