I am puzzled by a sticker on top of my air cleaner; "360 HP".
There is also a sticker with "454" and another one with "Turbo Jet".
As far as I know, the 454 in 74 was not 360; it was 270.
My quick google research tells me that the 70 Chevelle had a 360 HP 454 and Corvette had a 360 HP in 61-62, but on a 327.
The previous owner had a Chevelle and another muscle car of the 70's. Maybe he just swapped the covers....
Which engine number should I verify to satisfy my curiosity ?
