Unfortunately a catastrophic...
Unfortunately a catastrophic engine failure kept Hinkle Performance from making the required dyno pulls, but this 361 based big-block impressed everyone making 595 horsepower prior to the failure.
Hinkle Performance achieved a milestone during our challenge, but it may not be one they're proud of. While making their qualifying dyno pulls, Engine builder Buck Hinkle noticed that power was down from the pulls they made at home, but no problem was apparent. Unfortunately, their next dyno pull resulted in some expensive noise, and their 404 cubic inch big-block suddenly stopped running. After a quick inspection, the engine was deemed permanently broken, making it the only engine in seven years of our contest that had to be removed from the dyno without making its required pulls. Further inspection revealed that the engine's valves lacked enough clearance from the cylinder walls, resulting in a broken valve and major block damage. At 595 horsepower and a rating of 1.47 horsepower per cubic inch, the Hinkle Performance entry came in well below our $5,500 budget and would have certainly placed higher had it made the required pulls.
