What headwork are you planning? What size cams?

Will you be running socks or have a cover made up or let them run open?

I keep wondering about that 48mm bit on the OBXs. If it were Webers we were talking about then they'd be twin 48DCOEs. In an 1800cc motor you'd only be using those if you were looking for max power at around 8500-9500RPM. At road speeds they'd be p1gs.

I have the greatest faith in you Grant... if anyone can make them cold and hot start, you can!

They are still too big though :)
