Stack Height Testing with 427 Windsor on Ford Stroker Engine 500hp

We tested three different stack heights from Borla on a 427 Windsor Ford Stroker Engine to see differences in HP and TQ throughout the power range. Peak Numbers: 35mm Stack - 493HP/446TQ 50mm Stack - 495HP/451TQ 100mm Stack - 488HP/451TQ Interesting that the tall stacks perform better throughout the power band until high RPM when the shorter stacks shine. We do testing like this all the time at Prestige Motorsports to continually develop our packages and provide our customers everything they need to choose their perfect engine combination.
