I will get in contact with Peter Boyd and see whether he can provide any additional details. Unfortunately I don't know the previous owner and was not provided with any type of log book. Best I recall it was used for oval racing in California and had an aluminium block V8 installed..
Engine is long gone but have secured a replacement Lotus Ford Twin Cam as I am quite sure it was orginally a used for Formuiula B - either a BT21A or C. I have the original Hewland transmission and all of the other bits and pieces.
I will let you know what Peter says.
