robolots 35 Posted May 19, 2014 I'm just looking over an old GM SR and it has THR stamped on it, plus some numbers. I believe THR is Michael Lee, but can anyone confirm who it is and pm me or send me a number for them if possible as I want to trace some history on the engine. info@robracing.co.uk Thanks Rob C Share this post Link to post Share on other sites
