| RE: Torque number for 428 CJ |

P,
The numbers came from the Fomoco shop manual, 1968 for the 427 and 1969 for the 428 CJ. There was a press release detailing the 1968 1/2 CJ making the same torque number at a slightly different RPM, I have a copy someplace but not right at my fingertips.
I think the numbers are available on Scott Hollenbeck's fabulous site:
www.428cobrajet.com
There has been an old story that the 428 CJ made more torque at a lower RPM but the factory numbers don't support that theory. In the case of these motors, either makes plenty and your boat 427 numbers sound plausible as well.
