I am not sure where the ones on my 1969 Cobra 428 SCJ came from but they are nothing like the pictures shown. They have runners that go into the main section and exit at the back. The drivers side had to be cast to clear the steering collum, so I lost about 50 horsepower there. When the engine was out it was ran with tube headers and the stock ones on the dyno and with the tube headers it was right at 500 horse and with the stock cast ones it was right around 450. I kept the stock ones so I wouldn't have to cut the shock towers to get the tube headers in there and I wanted to keep the original look.
