the 65 396 Vette fit A / Stock? Like i stated I am just curious.
Thanks in advance, Alan jr.

According to the NHRA Classification Guide, the '65 Vette was factory rated at 425 HP, but, with OEM heads, it is NHRA rated at 375 HP, which gives it a factor of 8.06 which makes it a "natural" A/S car (8.00 - 8.49). With replacement heads it is NHRA rated at 385 HP which gives it a factor of 7.85 which makes it a "natural" CC/S car (7.50 - 7.99).
