vortech pulley boost? Two questions. What are the stock sized pulleys for an s trim? Also how much boost would a 7" crank 3.33 charger pulley make on a stock headed 9:1 compression 355? With cc503 cam?

I think stock pulleys are 6.5 crank and 3.33 blower. With the 7 inch it should make 6-8 psi. I could only make 6-7 psi with a 7.8 inch crank and a 3.33 blower pulley with a v7 ysi. I'm not sure why it doesn't make as much boost
