Oldsmobile 455ci - Fortified 455
|
Once the Offenhauser tunnel-ram and dual Holley 750-cfm HP carbs were installed, the motor was ready for its final dyno runs. The final tally was 452 hp at 5,400 rpm and 541 lb-ft of torque at 3,700 rpm. While we did gain about 14 horsepower, it became apparent that we had run out of room with the stock heads, and they were now our limiting factor. Jetting the carbs and adjusting the timing did virtually nothing to affect the power output or running condition of the motor. It's clear that we wouldn't be able to take full advantage of the tunnel-rams potential without some radical cylinder head work. On the other hand, Edelbrock does offer aluminum heads for the Olds that put out some pretty impressive flow numbers. Maybe next time! View Related Article
