Re: 1964 Motor Identification
Almost. It is a long shaft.
V4 = well it means it is a V4
M = 90hp
L = Long shaft
-10 = it is a 1964
S = nothing, don't worry about it.
Has a four barrel carburetor, expensive to repair (parts cost).
Has the 20 amp alternator, simple enough if you understand it. A head scratcher if you don't. See remark about the junction box.
There is nothing wrong with the Electramatic shift if in good condition. If neglected or abused, it will cost $$$ as will anythng else that is neglected or abused. If it does not include the Electramatic remote control and junction box, it is not a complete motor. That stuff is worth as much as the whole rest of the motor.
