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.

So if we have to guess a Pontiac, its either a 68 Bird RA2 factored at 390hp or maybe a RA5? LOL but we're getting desperate here.

Or it was a 67 Comet 427/410 and somebody thought it was a Pontiac?

Lets say that was the case. Would someone really build a car for that class @ 8.46? I don't think so. IMO that looks like someone built a car for the 8.50 class and ran really good and got HP that moved them up a class.

PS the RAV was a small displacement engine for Trans AM like the Z28. I don't think enough were built for it to be NHRA legal.
