67-70 combo |
|

|
|
|
Combo 67.
Combo 67 uses the basic Brodix heads and Victor Jr. intake. This combination makes 401 HP and 456 ft-lbs of torque. Compared to the previous combo, these heads make 8 more HP and 21 more ft-lbs of torque with the same Victor Jr. intake. Compared to Combo 64, with the same heads and RPM intake, this combination produced 4 more HP and 11 less ft-lbs of torque. |

Combo 68.
Combo 68 is the last of the 408 cu. in. combinations. The Victor Jr. intake is combined with the -8 heads to make 417 HP and 460 ft-lbs. This is 16 more HP and 5 more ft-lbs of torque than the other Brodix heads with the Victor Jr. intake. This combination produces 7 more HP and 16 less ft-lbs than the combo with the same heads and the RPM intake. Again, the Performer line proves to be more of a streetable intake than the race-oriented Victor Jr. |

Combo 69.
Combo 69 comes from a 1996 reprint of a Holley article in Chevy High Performance.
Holley components are used to produce an engine that makes 400 HP and 400 ft-lbs of torque. 110 octane gasoline is used on this engine, and I almost decided to omit it from the combos. I would assume that the higher octane will raise power at least 10 HP, but I am unsure of the exact increase. Anyhow, maybe this combination is still helpful. |

Displacement: |

Carburetor: |
Holley 750 vacuum secondary (110 octane gas is used, so the HP and torque numbers will be a good bit higher than with ordinary 93 octane.) |

Combo 70.
Combo 70 comes from pages 29-31 the 2000 edition of Petersen's Hot Rod Camaros.
This engine is a 406 cu. in. version that is to be put in Mark Stielow's "Thrasher" 1969 Camaro. The build uses some impressive parts such as a roller cam, a Cola crank, and CNC'd Edelbrock Victor Jr. aluminum heads. The roller cam is pretty stout, and the lift seems huge with the 1.6:1 rockers; however, the EFI helps this engine to still be streetable. Note that the HP peak is at 6000 rpm, while the torque peak is at a low 4000 and 4100 rpm. This torque peak is only at 67-68% of the peak power rpm. Most engines have peaks that are closer, with the torque peak occuring at 75-80% of the HP peak rpm. Perhaps the EFI is the reason for this. |
