Can dome pistons make more horsepower with number 8 heads on a Oldsmobile 350?

Yes, using dome pistons with number 8 heads on an Oldsmobile 350 can potentially increase horsepower. Dome pistons can enhance the compression ratio, leading to improved combustion efficiency and power output. However, this modification must be carefully matched with the rest of the engine components to avoid detonation and ensure optimal performance. Tuning and proper fuel selection will also play crucial roles in achieving the desired horsepower gains.
