408 stroker vs procharger 360

I went through the superchargerstore when I ordered everything, comes with everything you'll need to bolt it into place. Pulley's, Brackets, bolts, waterpump, hoses,belt/tensioner, clamps, carb hat,blowoff valve etc... Install was no problem at all, tech support it great if you do need it though.

If you go with a Keisler you can run a deeper gear, but plan on shifting like mad, the 1st and 2nd gears are lowered and put closer together. On my stock 4 speed running 3.91's I hit my 6200 rev limiter crossing the finish line at 122mph. Since then I have changed to 3.23's to make it more hwy friendly as well. 5sp overdrive would be nice on the street but I doubt you'll be able to make quite as good of times...probably still could be in the 10's though. Depending on tire height you might need overdrive to get through the 1/4 in a 5sp and anytime you go below a 1:1 final drive ratio you're loose more tq multiplication to the wheels.

All depends on what you want and how much cash you are willing to devote to this project. A turbo setup would be cool and provides some other options that a simple Procharger install won't do. But it would be more complex, require greater fabrications and tunning to make everything work properly.
Prochargers do eat up a little more power than a turbo would but with nearly 50% power increase per 7psi of intercooled boost....the power to drive the supercharger starts to become arbitrary.

Just do lots of research, talk to guys that have build monster street strokers, prochargers, and turbos and choose wisely :-)
