Not Ranked
Not taking into account the type of vehicle, or the type of exhaust manifolds.
The stated HP figures that are well known and written in Ford manuals and car brouchures (sp) are as follows.
The 427 with 2 x 4 carbs was advertised at 425 HP
The 427 with a single 4 was advertised at 410 HP
The 1968 W Code 427 in the Cougar GT-E was advertised at 390 HP. So is that because of the insurance worries, going from 410 to under 400??
Kind of goes along with the 428 CJ at 335HP
The SOHC 427 with a single 4 was 617 HP
The SOHC 427 with 2 x 4 was rated at 677 I believe
If you ordered a 427 2 X 4 engine at the parts counter, it was advertised at 485 HP.
Since Shelby and Ford didn't car about insurance companies and HP ratings for the Cobra race model, it was rated at the 485
