But I don't believe it had as much power as they claimed. My 69 NASCAR Cobra with the 428 Cobra engine which was rated at 335 horse I had dynoed and it came out at 440 horse using the original exhaust manifolds which were the same as the 64 427 had as it has 427 heads and the bottom end is LeMans rods and stuff.

When I picked up my motor from Keith Craft's shop he had a couple 428 CJ restoration (stock) motors sitting near the dyno room after testing. I asked the dyno operator what they ran and he quoted getting around 430 to 440 HP I believe from memory. |
