Dave,
I have a 55 eng out of a 4 door parts car that I know has shims.
Also have a 56 from a 2 door sedan that a guy Big blocked.
And a 57 that he threw in for good measure,quote'Dont need this 6 cyl. stuff no more'cause all he had was v/8 stuff after that.
Your saying the 56 and newer dont have shims,Thats Great news.
Guess I only had the bottoms open on early 55 motors.
regards,
steve sr.
