Dave,

I enjoyed your post. I have a carbureted Windsor block with 2V heads and am just putting the engine back together. I was looking at a similar cam, -561 vs. -551 except for the Windsor block. I finally decided to go with a Ford cam because the Crane was too much money, $250 for the cam, ~$350 for the lifters and amazingly enough ~$350 for the springs and retainers. I just didn't want to spend $1000 for a cam setup. The Ford A351 cam looks similar although the torque curve is not quite a flat on my Dyno 2000 and of course it's a hydralic cam rather than a roller.

It is also interesting that the dyno results matched your computer pretty well. My Dyno 2000 gave 457 hp @ 5500 and 478 lb-ft @ 4500 for the -561 cam with my setup. Looks that might be pretty close based on your experience.

Where is Clearville, PA?
