hi all, any educated guesses what i should run in my old girl when i restore her? i used valvoline 20/50 on a rebuild in 1986 and wiped out new cams,new followers and new stainless valves ( all norman hyde stuff) so a little reluctant to use his stuff or valvo again. p.s. it has a shared engine-primary and separate gearbox, and recomendation was for 50 mono in gearbox, and 20, 30 or 40 mono in engine and primary depending on season (can i use gear oil in box, no guesses please) thanx in advance, john
