What compresion should i have if i want to put a super charger on 351?

RiCeFrYeR · 05-17-2005, 11:12 AM

I have came to the conclusion that i am going with a 351. And i am going to try to get it to about 380 and then put a super charger on it. I am thinking that this should bring it to about 500hp. But i am thinking i sould not have more then about 9.5/1 or 10.0/1 compresion on the motor. I am looking at maybe buying the world man of war 351 making 380 in my summit magizine. And then with the supercharger.

But first i have to sell my truck. Anyone interested?

I will keep that in mind. But for now i am looking at a vortec. They have a supercharger that will run up to 20psi boost. I am realy going nuts though on this emissions stuff. I live in dallas and we have to have emissions on our cars. I do not know how i am going to do this if i go with a N/A car. I have been looking areound and i think i am going with a ford racing motor a 351 and it pushes about 400 as is out of the box and then i am going to put the charger on it. But like i said how do i get it to pass emissions test legally?
