Im looking at getting a second hand clevo for the slug, any Ideas what a good compression figure is for a standard motor (PSI)? both OC and CC heads? Cause it has been rebuilt so who knows what heads are on it.

My XD repair manual says 150 psi for a 351 OC.
I have CC on my mild 351 and have around 200 psi.
But it's more important that all cylinders read about the same, more than 15 psi differance between any two cylinders is too much. Some people like less.

Cheers. The engine is actually out of the car with no box or flywheel, so I can only turn it over by hand and cant get it warm anyway. It looks pretty good tho with the covers off, Im pulling the sump and some bearings tonight, if its good in there than I'll grab it I think.
