Bolt on Supercharger for 1968 327 Chevelle

I am looking to add power (low end torque) to my 1968 Chevelle. It has a 327. I'm thinking about a supercharger. Any suggestions or recommendations?

it doesnt really matter what size small block chevy you have any one from all sizes from 327-383 have the same block size just have a diff size crankshaft(the smaller the enigne the more throw you have) which means you can rev it up 2 higher rpms for example a 383 storker max rpm would be about 7-8k(getting all your power from 1-5k) and on a 327 having a smaller crank would have more throw means you rpm rang would b from like 8k+ getting the hp anywhere from 1k-6500

but in answer to your question you could buy a roots type supercharger kit wit everything needed from weind or a similar type comp goin through like summit paw etc for around 2800 and get everything needed minus carbs which you can go to a junkyard and grab a 2 quadrajets off some old chevys small block as long as all four barrels work will work as weel as a edelbrock or holley 650 cfm carb

and it should bolt right on wit just having 2 do some belt work as the supercharger will take a big ass serptine belt type thing(you can tell what i mean buy just seeing a pic)

Thanks for the advice. I appreciate it.
