with the 525" making 1300HP it would take 16/18 psi i would think not having to stuff the extra psi into a smaller 368" that may need 25lbs to makeup for less cu.in.with a int gearing of 5.4/1 the pulleys would need 1.79/1 for 7,000 rpm at max rpm,flow and the F-1R at 68,000 rpm.
i just wanted to bring some info to the post to relate to.




Customer of mine 3.33" Crank, 4.185 bore....367" motor.... 16 PSI boost 5.30 @ 131 @ 3450 lbs. I think you need to rethink you're 25 PSI on the SB idea to make power.
