The 8.5:1 NA and TN 550s have 22 degree timing. So should the TSIO-550s with 8.5:1 pistons. The 7.5 CR variants have 24 degree timing.

Don't forget to throw that into the mix. <g> These have about a 14.7 multiplier instead of the 14.9 of the 8.5s. Walter, 24 compared to what? Are you saying 8.5:1 are less than 24 degrees? Colyn
