I have a Ford SC crate motor in my '92. (Looked like a brand new motor when it came in from somewhere in Kansas, but I guess it was probably a rebuild) I put it in back in 1999 and it has about 60K miles on it now. No complaints.... (It did like to shear off balancers until I got the BHJ...maybe too much torque in the new engine for the stock balancer???)
