Porting the intakes will do more for you,
and the 70 takes extensive mods. I did
one for Capt. Kirk (silver2000) and he got
post removal and crossover tube work to
boot. He is gonna run an SC with it. But
to add to what these guys said, I would
use it for high RPM 3.8's, power adder
setups and strokers. Most street 3.8's
are fine with a stocker that is modded.
With a cam and porting, I would say YES.
For minor mods, (just boltons) and modest goals, maybe not.
Depends on your budget, and headers are not
a good dollar/HP ratio on near stock cars. But the LT's and a cam and porting is a great combo!
Yes, since you are getting the cam, porting, and all that.
But if you were staying NA the cam and or header requirements
would be change, you can do it pre-blower but I would say
you stand to gain minimally in teh pre-blower setup, your cam
has extra Exhaust duration (for the blower) and that plus LT's
will over-scavenge the exhaust a bit, but at this level it may be
a very minimal power (imperceptible) power loss, but perhaps
a noticeable mileage gain!
