The Stovebolt Site Forums The Shop Area Engine Shop split exhaust manifold

I got my Dyno results.
The 235 with the Corvette manifold made a max of 87 HP and 176 ft-lbs of torque.
That's a gain of 6 HP or about 7% over the stock configuration. Pretty close to the McGurk report.
Here's a chart.

YMMV.
