I have a '69 Windsor in my '88 and I did a lot of research about these motors. What I found was the 2 bbl motors were 9:5.1 comp. and the 4 bbl motors were 10:7.1. Mine started out as a 4 bbl motor and I had the 1.84 / 1.55 valves in the heads with flat top pistons. That's how I knew it was a 4 bbl motor. My Windsor is now .030 over with forged pistons, ported/polished stock heads, screw in studs w/guideplates and a .536 - .293 solid lifter cam. I'm running a victor intake with a 750 double holley. Runs excellent. 11.40's so far in the quarter with 2500 stall, and 3.73 rear gears.
