Old thread, new question.
In the current 1964-65 NHRA class. guides, they list the 426/425hp-8v race hemi. I deduce that this was factored to about 500-505hp so it put the cars into S/S, below the 7.00 weight break.

But they also list a 426/400hp-4v race hemi. I wondered why (besides NASCAR), but if factored the same way, say up to 480hp or so, that would put the 4bbl hemi cars right around W/P=7.08 so they could run in A/S for 1965.

I don't even know if the 426/400-4v race hemi existed in NHRA in 1965, but if it did, was it really factored that way, could those car run in A/S=7.00, and why is there no evidence of that happening?

Leads me to believe NHRA did not recognize the 426/400-4v, whether factored or not?
