Also, it should not have ribs on the sides, if it is ribbed it has a service block (post 1970), also look for any visible defect like a crack around the freeze plugs, etc. All this checking should give you reasonable certitude that the motor is what it is supposed to be. As far as the condition, pull the plugs and see if it turns freely. A good 427 Sideoiler block alone will cost you 3 to 4K. I forgot, the patina is important: dirty, a bit oily, faded paint and bolts looking like they have not been messed with! The rest is a gamble, if the price is right!!!!!!!!!!!!!!!!!!!  |
The variety of opinions on this subject is always amazing. There was a time around the FE FORUM not too long ago (3 years or so), that service blocks were considered by many to be desirable because of a higher nickel content in the later castings. You know, "continuous improvement" and all that.
I have no clue, and don't care what it's worth, but I do have a incredibly reliable service block SO.............
