I need another life!!
If you get stuck, I use B.E.Randall, of Hepworth near diss, 01359 251888 for all my engineering work, they are not the fastest turn around as always snowed under, but are ace, Brian is I think 70 now, built his first race winning engine at age 14, so should know what he's doing by now!!
He's also going to be making/casting his own pistons and rods etc so he can control quality better.
