I think we can assume that it was built for either Gurney or, Shelby, or even for both to run, in the USRRC/Can Am, F/A-F5000.
Shelby's, '63-'64, King Cobra, only lasted 2 years, in his name. Gurney, campaigned, his Lotus 19 and Lola T70, until '69. Gurney's MK5 F/A-F5000 hit the track in '68, mine was raced in '68 so, it would make since, that it was designed and built, before the end of '67.
I also, now think it was a road racing dedicated dry sump, because of it's 2nd stage, that helps under braking, and designed and built, between '63 and '67.
If only I could get a look at the Shelby system, that was used in '63.
Randy, do you have info of what the ASK numbers where used for, before and after my ASK2233? Is the "A" specific to the engine group?
