Now you may be able to teach me something when it comes to this, but the 4.6 modulars (including the 5.0) never really responded that well to h/c/i....atleast in comparison to the LS-series and how they respond. Has this changed since the 3Valve came out? Do you really think outside of a blower/turbo that there is a lot of power to be made?
What does a cam swap on the 05+ GT's result in?
The key with these Modular engines is CR.....they respond more with CR than any other cars that I have played with mostly because of the design of the OHC and their tight tollerences.....the heads are the weak point of the 2V in stock form.....ported they respond very well and produce a broad power and TQ curve with the right cam combo......not bad for 281 CI's......compared to the old shock 5.0 the 4.6 can rev and peak higher whick makes up for the slight loss in TQ but will add alot of top end power.......the 3v is an awsome designed head from the factory and when ported flow close to the same as the 4V's ported....but with more bottem end flow numbers.....I have seen stock ported heads for a 3v with a stage II cam push 380hp......and a few companies are claiming 400 now.......I am staying 2v for now as I just Purchased the TFS 44cc heads from Fox Lake and Ron will port the runners for me........they will flow 260cfm without touching the bowls......very impressive......the modulars produce a great average HP and thats what makes them fun to drive.......
