Dear Mr. Hall, From our telephone conversation I gather that the bottom gear I am proposing will be all right for you. This will give just over 50 M.P.H. at 4500 R.P.M. I note that we can fit a new camshaft, pistons, larger inlet valves and Kelmit bearings, so that I can now go ahead and build up the unit. I am also preparing an exhaust system. I note that the list of jobs requiring attention on your present chassis is in the post. Wishing you every success in the Isle of Man. Yours sincerely, FOR ROLLS-ROYCE LIMITED. | ||
