The addition of a supercharger to an engine will pump in more air resulting in more power. The Crank and Rods must be able to take the added strain and if they are forged steel they will take an increase in power but probably for a shortened period between overhaul( can you say 4.5 seconds?)
The block should be a 4 bolt main, preferably with angled outer bolts.
If all the bottom end pieces are up to the task of taking the added stress, it is just a matter of lubrication, valve train(other threads indicate to me that there is a lack of understanding on this) ,cooling , mixture and timing control.
With the current crop of EFI engines and PCM's it is pretty easy to control the combustion process to keep detonation at bay. Diablo and FAST (fuel air spark timing) systems that are easily tunable, even via cell phone!
If the temperatures are controlled-coolant and inlet air-(intercooler) ,larger injectors are installed, and a control unit for the fuel and spark properly set up for the type of driving you do , there is no reason that you can't run an engine for 40,000-60,000 miles.
We have been doing several install/tuning of various centrifugal superchargers(Procharger installs, tuning some Paxton and Vorteck) on varied milage cars running from new Mustangs to 20 year old cars with 80,000 miles.We did one on a 92 6 cylinder Mustang that was converted to V8 from Crown Vic POLICE car that had well over 100,000 miles.
The power levels are awesome and the smaller engines get good milage.
A Cobra has plenty of room for the install and intercooler and you will find that a smaller supercharged engine will make the power you want, but still have nice cruising street manners.At the lower power levels it won't have the cooling needs that the big blocks need.
I would be happy to answer any questions you might have about the mods needed for supercharging.

exactly...its a common misconception that power adders blow stuff up....wrong...they add power....improper engine setup & poor tuning will blow stuff up...on a properly setup nitrous 393" sb2, i routinely sprayed 800hp shots...motor went 200+ passes and the bearings looked brand new...blown alky motors like to eat themselves abit faster and the nitro monsters have BIG appetites...many variables can effect tune and how to tune...a bunch of small steps will go a long way...greedy tuners get a trip to the machine shop....oh i love powerheads
ring pkg for my nitrous motors was .380 down with .180 between 1st & 2nd...i also ran a hellfire top ring in .046 with a 1/16th second and standard tension
oil....blower pistons have thier sweet spot also but i'm a juicehead so i dont know
