I built several legal NHRA 1971 340 motors for stock years ago, circa 1992 to 1994, both of them made 430 HP at 5900 RPM with two different Isky legal "stocker" cams with round lobes on top, I tried one Lunati sharp nose cam, it made 10 HP less but made more HP from 5000 to 7000 on that average than either of the two otherIsky did work I advanced and retarded all three cams to find what they wanted on the DTS engine dyno at Pettis Performance shruggy This was with all leagl NHRA parts, iron J and X heads, "100" iron intake, legal Thermoquad carb. and so on work Gene Buhl used the same dyno and machine shop for his builds back then, he bought a set of "magic" cylinder heads for one of his motors, that one made 450 HP on the same dyno work BTW, if you built those motor using NHRA "blueprint" specs and did the math those motors calculated out to have 11.56 to 1 true compression ratio, not 10.5 to 1 shock I built 9secondPhils 418 C.I. pump gas W2 headed 340 stroker motor, it made 525 HP with custom ground Comp solid lifter cam and a Holley 950 HP carb. on a Eddy W2 Victor intake up His 1969 Baracuda fastback ran real low 11s on the motor and cracked the high nines with NOS shruggy IHTHs up
