We ran 9.2-9.29 all season long for 3 seasons.

We had a 427 sideoiler with Medium Riser Heads,
A SOHC Cammer engine
and finally a tunnel port 428.

All ran the same index and the same times.

67 FX Fairlane with C6 tranny 5,500 RPM stall. One run after the next after the next after the next. Clock Work. This car is consistent.

(By the way the Cammer was real fun, but it was a loaner engine and went into a show car. The 427 side oiler went into an AC Cobra kit car after being detuned. )

The 428 had the largest physical camshaft that would fit without the rods interfering.

The cam was 326 duration 268 @ .50 inch and 640 lift on the intake and exhaust. The overlap was 110 degrees. When the car idled, the intakes and exhaust were open almost a half cycle. You could smell the RAW gas and the flames out the exhaust at night were quite impressive.

When we had the car at 7,000 RPM and up, the engine ran like a rotary. We had it balanced to 0.1 grams. The only failure is that we punched holes through two cylinder bores and ended up sleeving those two cylinders. The water never seized the engine because of the overlap! (Lucky me).

We lost just two races. One to a Hemi, and the other to a 500 cubic inch Chevy stroker. Both won by less than a door length. Both went through the trap at over 150 MPH. We finished all but two races we ran. One was the blown cylinder walls, and one was a transmission failure when the C6 case cracked and leaked tranny fluid all over the track. Every other race we won. CONSISTENCY PAYS DIVIDENDS.

Then engine dyno'd at 602 HP at the flywheel with two 750 Holley carbs on a tunnel ram intake, and 574 HP at the flywheel with a single 1050 Dominator on a single plane intake with 4" riser plate.
