I have Vauxhall VX4/90 FC for historic racing, in circuit. I've just received a letter from Bill Blydenstein, I asked him some advises of tuning engine. I got some very good hints, but the biggest thing was two homologated parts. Mr. Blydenstein wrote, that tubular exhaust manifold and close ratio gearbox were homologated back in 1963 and also in FC model. My copy of homologation 1370 do not have these parts, maybe they are in extra pages ? Can anyone help me to find these missing pages ?
Thanks and regards, Jukka
