Have found two trucks-I think one is a 57 and the other around 67. Both are three quarter or one tons. Both are V8. Can anyone tell if these are 283 or 327 by the numbers I took off the right hand front block. 67? VO716Y3 and 57? F217D. Too cold to go back and get casting numbers. Thanks in advance! Oh by the way the 67 had a good front clip.
