anyone have any numbers on the gains for a port/polish on the heads on a 3.9L,
with a stock readline?
I'm asking because Im getting my parts list together and would like to avoid
yanking the cam out and having to have the computer reprogrammed. Or can the
computer adjust so long as the cam profile isnt too radical? Im trying to avoid
downtim as the truck is a daily driver and I need to give it some ballz so I
can race it at the track without running 17's and looking stupid :)
fyi, its something like this:
2nd new/rebuilt set of heads with port/polish (gonna grab em from ebay and have
them taken to a shop near me that does headwork)
1.7 Rockers (the harland set from summitracing)
new set of "long-tube" headers (stock ones will most like not come off/break)
new 19lb/hr injectors (have them, need to install them)
new doubler-roller timing chain (have, need to install)
superchips tuner 3715 (used to have this, its in the mail)
not touching the cam because of computer issues (unless it can adjust)
specifically, this one
http://www.hughesengines.com/partDetail.asp?partID=10697&eTypeID=10, as I cant
afford the downtime.
thanks.
