I'm building a 600rwhp car and I'm in the final stages of getting my parts together for the build. I wanna say I'm 90% sure that the 44cc's are the ones I need since I'm supercharged and getting a cam and intake manifold done at the same time. What spring would I need and does anyone know of a online store that has a good deal on these? I ready to buy this things possibly today or tomorrow!

 

Valve springs? Trick Flow sells these heads with either a 90# or 125# spring. Get the 125s. It's a little more money but needed on a high rpm or FI car.

 

Any idea who sells them both and gives a good deal?

What's your fuel setup?

 

Twin set up with a boost a pump.

 

What twins

 

What's #'s are you putting down with your current setup?

 

Putting down 420hp/453tq at the tire. The set up is a twin Focus fuel pump with a boost a pump. I know the entire set-up it ready to handle 600hp when I bought it.

 

your not going to hit 600 horse with a p1sc, not even close
