Supercharger
Is it possible to put a supercharger on a motor with 10:1 compression? Don't want to shorten the stroke or use block flillers. If supercharger is to of the equation 150 shot nitrous here I come.

NO.
...with each pound of boost, your effective compression ratio raises. For your motor with 10.5:1 with just 4 pounds of boost puts you at 13.5:1 and at 6 pounds nearly 15:1.
(You can google forced induction effective compression ratio and see a chart)
8 to 8.5:1 is common for a street roots blower. Big power, high boost they can get down to 7:1. Some guys pull it of with low boost on 9 to 9.5:1, but I'd never do it.
More boost with lower compression is better then low boost with higher compression.
