Hi, I've recently aquired a mk3 triumph gt6 and I'm looking to upgrade the engine for road use and maybe hill climbing. Can anyone recommend a good place to have the work done or to source parts from? I'm not a mechanic so will need someone to do it for me. I've done a quick web search and I've come across Jigsaw Racing but they're quite far from me, but a possibility. does anyone know of anyone around the sheffield area?
