Let me just leave this right here.
I love roots blowers, and this article is old, but LPE still offers a warranty and that seems like it might be important to you.

In case you are not familiar with roots blowers, the provide full boost at low RPM. Your torque curve is no longer a curve, but a flat line. You may give up some on max HP, but for drive-ability and smiles per gallon, top notch.

Unless you can tinker with it yourself, which you said you are not mechanically inclined, stick with the cam and tune, with headers. That will require the least input from someone holding test equipment and a wrench once it's set up.
If you're going to take the heads off though, you may as well get some machine work done to them. Porting, springs and lifters to help that cam along.

I have a completely stock 2000 C5 auto with 20,000 miles. My plan is to likely keep it for 20+ years (no--I'm not kidding). I only drive it about 30-75 miles per week, mostly over the weekend. I just bought the car over the summer, but once spring rolls around (I'm in PA--too much salt in the winter to drive it), I may drive it to work 1-2 days per week, which means I'll probably be putting 100 miles per week on it from March-November...so total mileage of about 4,500 miles per year roughly. I am looking for good gas mileage (currently around 27 mpg with stock 2.73s) and same reliability (or similar) to what it is now. So, I am debating putting a few thousand into it for performance mods. My goal is roughly 430-450 very reliable, not going to kill the engine, transmission, or differential, crank horsepower. My options are either:
A.) East Coast Supercharger kit with restrictor plate at about 5 psi, which should be 450 crank hp (or so I'm told) and Corsa Xtreme axle back exhaust
B.) Combination of long tube headers, FAST intake, Callaway Honker, upgraded throttle body, Corsa Xtreme axle back exhaust (I'm thinking all these modifications should get me to 415 hp at the crank (?)) for slightly less than the supercharger from ECS...and maybe, a mild cam for ~25 more crank hp
The thing is, I am completely undecided, and in all honesty, don't know all the advantages and disadvantages of both. I love the idea of the supercharger, but I'm told my block has a 2 bolt main vs later LS1 Corvettes with a 4 bolt main, which may kill the engine with a supercharger. Any truth to that? What is a 2 bolt main vs 4 bolt main and which does my Corvette have vs other C5 Corvettes? I'd like to keep all modifications to $7,000 or less, with a goal of low, low 12s or 11.9 if possible (not going to drag race it--just saying how fast I'd want it to go as I think C6 autos from 2005-2007 run low-mid 12s and I want it a bit faster). I'm open to any and all ideas and suggestions as I'm far from an expert on this. Any advice would be very much appreciated.

When you get ready let me quote you some parts.
