I bought a motor core and it said it was ported and i can clearly see the intakes are but the exhaust looks pretty stock/small. I was wondering if anyone had the deminsions of the stock FD exhaust port.

Dont have that info handy but it is very easy to tell if they have been ported. If they have not then the port will be dark and it will look like cast iron not ground smooth iron. There should also be a distinct line where the top of the iron face meets the interior of the port. Once the iron is ported that line disappears. If you post a pic we could tell you in 2 seconds.

 

47mm wide and 20mm tall. This is the lip of the port just before the sleeve.
