Thanks all for your answers !
It's a real pleasure to see that people can help me !
@Mr. Yuck : I know I can obtain 500HP without supercharger but I really want it, I looooove the beauty of the roots!
About the book, I choose this :
There are a lot of informations inside, I am reading it !
@webemopes : I have to buy all the parts so I think take all in new. For the heads I agree with you, Edelbrock Performer RPM seems ok !
You think that a 871 is better ? why ? it's for more horsepower no ?
@Streetwize : thank you for your answer ! About the crankshaft, something like that is ok ?

Indeed I will do check the block by a pro but he said to me that he need a crankshaft for some controls.
Ok for the Edelbrock RPM heads !
for the other infos, I keep all your informations in a file, I want to build the engine step by step, otherwise I will not find the way..
thank you one more time !
I find this table on Holley superchargers :
So I think that something like 8.0:1 static compression ratio with 4psi of boost (10.2:1 effective compression ratio) is good, no ?
