The Stovebolt Site Forums The Shop Area Engine Shop i want more power !!!!!!

I achieved some modest gains with better exhaust on my 55.1 235.
It's stock except for a corvette exhaust manifold and dual exhaust with 22 inch Smithys.

dyno results

I picked up 11 lb-ft of torque at 2000 RPM, about a 6% gain,
and 6 HP at 3000 RPM, about a 7% gain.

regards,
Leon
