Recently got this vehicle. 1966 mustang C code with C4 trans
Engine running butter smooth, tested cold dry compression at 140-145 across the 8. Have 25000 on the odometer, not sure been turn over before or not.
The engine looks pretty old, because all the blue paint is chipping off, and rusting on the exhaust manifold, but the compression number looks really really good to me. I thing i should expect a never rebuild engine at this age with 125000 or maybe 225000 mi to be at around 130psi or...

Do I need engine rebuild? 1966 C code
