Steve Ducich’s slant 6 and what it took to make 300+. Steve heavily ported the stock head and if I remember correctly it cranked 210-220 psi. They crested the 300 mark with 7-1/2 psi. Also, they pushed the head gasket out on the 328hp run.
Yeah I remember that. They used an el cheapo head gasket for a blower, but if I remember right, the blower kinda fell in their lap at the last minute, so rather than tear it down, the went forward. lol
