We stuck the engine in this morning in about 45 minutes No problems other than my back after all is said and done. but did find my tall valve cover wing nuts will interfer with the double diaphram vaccum booster. so straight 1/-20 allen screw will have to do for lower rear on driver side. Best thing was that 2 neighbors stopped to comment on my color choice. Wife has commented several times also. At first she thought it was too red but has now changed hewr mind and likes it . I think it changes somewhat according to time of day you view it and sun or shade conditions. She also said that people would ask her at work when the car would be done and were watching the driveway for progress.
