Think a 168 but it's a funny one as it's a 14 with what I was told is a 16 cylinder, head, and CDI. But the 16 jetting calls for something stupid like a 178 main. Also, the pipe is fucked and that is strangling the top end. Combine that with being wide open about 1% of the time makes it both a twat and a bit pointless to sort out.Weston beach race is coming soon!!!
What main you got in there now?
