In your calculations for static compression ratio, I suspect you forgot the piston deck height. I further suspect that on that year motor, the piston is down in the bore by about 0.030".
cylinder 727
chamber 62
piston crown 22
piston deck 6
gasket 3
820/93 equals 8.81:1
That cam would work well with 9.75 to 10.0, but it ain't gonna work too well with 8.81, particularly being retarded by 2 degrees. You might try advancing it 4 degrees from straight up and see how it works.Last edited by techinspector1; 09-08-2008 at 02:25 PM.
