Re: Centre exhaust port baffle or fourth port?
I think the majority of power is found on the intake side. Some flow bench testing would be helpful to see how your intake and exhaust match up. I ran a dragster with a similar sized motor and the 425 eliminator, three exhaust ports, made power to at least 7000 rpm. I did a lot of port and head work. John Bradley ran multiple exhaust ports with great success back in the day. Opinions will likely be all over the place on this. Disclaimer: I do not compare myself to the legendary Mr Bradley.
