I have no basis for that factor other than it makes the car fit.
3300/390=8.46
Any factor less than 390hp will knock the car down into C/SA=8.50 class.
Why would the RA2 be factored to 390hp when the RA4 was only factored at 380hp? Hard to explain.

IF all the info you have from back during that time period is correct, then:
(1) What year could the '68 Bird I posted a pic of have run B/SA ?
(2) What year could the '69 "Hatari" Bird have run B/SA ?
Both obviously DID run B/SA, at least 1 year, at least at 1 track, under some sanctioning body.
When ?
