I have the 5.7L with an Alpha 1 and a stainless Vengence prop my numbers are here: 212 shabah 5.7 mercruiser alpha 1 prop help

It sounds like you are overpropped though, I would have expected that to be a reasonable match to the 5.0. You want your WOT to be between 4400 - 4800 rpm. You sure the tach is good?

It does seem that the rpm's are a little odd yet the speed isn't too far off. Access the back of your tach & give the little dial a spin before setting it back to 8cyl. Is the prop in good condition (no nicks/bends etc)?
