Researching some of the statistics I've read that the 1967 GTO came with the following engines:
1967 Production
Two Door Coupe, $2871: 7,029
Two Door Hardtop, $2935: 65,176
Two Door Convertible, $3165: 9,517
--------------------------------------------------------------------------------
Engines:
400 cubic inch, 255 hp: 2,967
400 cubic inch, 335 hp: 64,177
400 cubic inch, 360 hp HO: 13,827
400 cubic inch, 360 hp Ram Air: 751
Total: 81,722 Available Engines
My question is, was there a 400 C.I. HO engine that came with Ram Air as well?
I've seen Ram Air kits that are being sold for GTO's that can convert the engine to make it Ram Air but I am worried about ruining the originality of my convertible 67' GOAT. Any help would be greatly appreciated. Also if anyone knows why the H.O. engine came with a plug in one of the valve covers? What's the purpose if any?
