Hmmm....really? My friend has a 94 12v reg cab 4x4 with 370 marine injectors, a 4k GSK and a #0 fuel plate. South Bend dual disc and a MBRP stack kit, it goes good!! He made 370 rwhp on a Mustang dyno, probably 425ish on a DynoJet. I like driving it, its fun and fast!!!! But I wouldn't wanna drive it everyday I like my Chevy alot more.
