Yeah its amazing that the GT40s were into senescence so early, even in canam. But the aero took off very quickly in canam, which the GTs lacked big time.

68 GT40 had something like 425 hp 4.9 liter Carbs
earlier gt40 with 7 liter made more power, not quite clear to me why it dropped displacement and power

69 917 came out with 4.5 Liter delivered 520 hp
the 4.9 did 600
5.0 630 hp

And with Bosch multipoint injection , i'm sure throttle response was better as well
