Dean House was in the process of restoring his 1967 Pontiac GTO, so he decided to bring us his 1967 400 to us for a rebuild.   Dean was looking for a basic “stocker rebuild” with some slight upgrades so that he could run on the pump gas of today and still produce the power that he wanted the car to make.  We used the original 1967 400 block that came out of the car and one of our Pro Warrior HO – 068 custom ground hyd roller cams as the basis for the build.

The engine uses the following components:

  • Stock 1967 2 bolt block with armasteel crankshaft
  • Stock 670 heads, screw in studs, new stainless valves, springs, guide liners, spring, retainers, keepers
  • 1967 Pontiac Q-Jet Intake with original carb
  • Eagle 6.625 rods w/ full floating pins
  • Moroso Stock Oil pan
  • Melling Oil pump with TIP SD-Oil plate installed
  • Total Seal Rings file fit
  • Federal Mogul Rod and Main bearings
  • KB dished Pistons for 9.5 to 1 compression to run pump gas
  • Druabond Cam bearings
  • Trend Pushrods
  • Tin Indian Performance Pro Warrior HO – 068 custom ground hyd roller camshaft
  • Lunati Hydraulic Roller LIfters
  • Stock valve covers
  • Tin Indian Performance Complete Gasket Set with TIP-RM300 Viton ® rear main seal
  • Felpro 1016 head gaskets
  • Stock refurbished Distributor
  • Taylor Wires
  • Comp Cams 1.52 roller tip rockers
  • Flowkooker Water Pump
  • Original Timing Cover
  • Reproduction Stock Balancer
  • Engine balanced and blueprinted
  • Dyno Tuned before delivery

Our last pull on the dyno was with 32 degrees of timing – pretty low and we kept picking up power with timing increases (we were not maxed out yet)  The fuel curve was still pretty fat and in looking at the last dyno sheet we short pulled the combo (engine was still making power / climbing at 5200 rpm.  We firmly believe that once we have this combo lined out it will make over 400 HP!  Should be a fun ride in Dean’s ’67 GTO!



The engine makes 12+ inches of vacuum at 900 rpm with this combination!
