I'd like to give a third option.
A quality H/C/I setup.
The less boost you need the meet your goals, the better the reliability and longevity is going to be.
Unless the ported E7's are some kind of $2500 race port to meet a class, the are still restrictive and are likely little better than the boat anchors they are unported.
While I don't hate the E cam like some do, it's a low 5000rpm cam.
The original edelbrock intake is meh.
I just don't believe in strapping a supercharger onto an engine that has a less than mediocre top end. Pumping boost through a restrictive top end rarely goes well.
And when it doesn't work out, you now have to pull a supercharger or turbo off that top end to fix or replace the mess you have made.
Not everyone has the means or finances for a dart block (if you don't, that should cross the turbo off the list), so imo you build up the h/c/I then move on to a
vortech with the least amount of boost as possible to meet your goal.
I just don't believe in skipping a step (the hci).
Consider some AFR 165's, a custom cam, RPMII intake, 70mm TB (could go bigger, but you will have to port the opening of the intake).
Another note:
When comparing turbo's and superchargers as options, it's not really fair to say 0n3 or vortech.
More like should i get an on3 kit or a powerdyne. It's a much more reasonable comparison, since in base form, they are both going to blow up.
Hellion vs vortech would be more fair.
