Early LA 360 Blocks
I don't know about the high nickle blah blah, but I do know about the other. I have personally bored 3 early 70s 360 blocks .100 over and one 1977 360 block .070 over. People get confused when talkin about cylinder thickness because they forget to divide by two. When makin calculations for cylinder bores, you have to consider the other side of the cylinder. lol I know plenty of guys around here who've gone to 4" with 318s. A LOT of them. At first thought, you think ****, that's .090" over....and it is...........but you're only taking .045" off each side. That kinda tells you the real deal. Most 318s will go that far...and truth be told there's probably room for a .030" over from there. ....now watch the flamin. LOL
