Thanks for the info, John! Now that you mention it, I think we talked about these part years ago, when you were about to get them! I am reading the 0.189" increase to the crank throw as giving a stroke of just under three and a quart, right at 3.248" which gives a 326.524ci displacement with a standard bore. That probably accounts for the 327 noted by olddog, above.

Did you use these in your 289 car?
