From Lowell D after he got the car home to Colorado Springs , CO.
“Also checked on the roll-bar stamp, 008-152. SCCA region 8 is supposed to be the Colorado region, so it appears the car initially started racing here in Colorado.
Found out some interesting information on the engine in the RP 16. I googled the casting number, 831C 6015 R34, and it appears that it is an uprated engine, from a South African “Sierra.” Although most of these blocks were cast with an “AX” on them, some were not. Supposed to have been produced after the 711 series block and weighing about 10 lb more. Used quite a bit in British Formula Fords and supposed to have the HD maincaps. ”
Keep up the good work Lowell
