My 383 is bored 30 over. #4 cylinder needs a sleeve. My machinist says that a sleeve will cause the adjacent cylinders to egg shape. I need some advice. :cry: :cry:

A lot of us would rather have a non sleeved block (i'm one of them) but in the case of my 340 I can't just find one anywere. My 340 runs low 11's in a 3200lb car with the a sleeve and no ill effects. When I was a GM I guy raced a 427 in 1981 that had 4 sleeves in it, same thing can't find 427 everywere. My buddy today (25 yrs later) has the same motor in his '70 Chevelle and is fine.1qwikScamp said:i'm not too fond of sleeves i would rather have an all natural block
