lol....cone shaped. !!! That is a machinist motto....to help seperate you from some greenbacks. You unknownistly believe that? .060" is quite a bit....but do not be discouraged. Are you friends with the guy? Ask him to mic at least ( 1 ) bore , top middle and bottom in front of you showing you the taper/wear. Originally 360's have a 4.00000 bore as cast/machined....all the way up and down the cylinders. If he can show you 4.019/4.029/4.039 variance anywhere in the bore, OR they have excessive rust, like the block has been sitting on the side of a metal shed with no intake or heads on.....I wouldn't believe that Machinist Lingo for a second.
I have torn down 200,000 mile small blocks with very little sludge, bore ridge, lack of crosshatch, or bearing wear....and yet again I have tore down 100,000 mile small blocks that have carbon/oil sludge deposits so deep you have to chisel them off....oil pick up screens partially clogged with RTV...wonder they even ran engines.
Do you have a camera? I would like to see some "Needing to be Bored .060" bores.
Anywho good luck...you have the right idea......its the 88-91 LA Roller Cam 360 you want....but I think you need a better machinist to begin with.
I am still ROFLMAO about the "Cone Shaped"
Hmmm, good food for thought there. This motor has been setting around, disassembled for quite some time, not sure how long though.
I am kind of friendly with them, and have done a few motors with them, so I do represent $$ to them.
Most recently, in 2007 I was not happy when I picked up the heads for my Dad's 340, that were on me. They had told me $300, and when I got there it was over $400. They dropped it down to the $300, but wanted to make sure I would be back. That is kind of a hot button with me, all the way back to my drag racing days. Machine shops have always nailed me for $400+ on heads, no matter what you do.
They have done outstanding work for me in the past, huge shop that can do everything.
Ask your machinist if they can align-hone and square deck the block for you, any block, if he says no find another shop to work with
Besides, for a "pooch" street motor why would it matter if it went .060 over? You are going to be buying new pistons anyway...
BTW, what did he say about your rods and crank? Those need to be good regardless of the bores
All good questions, yes they can do all of that, and I had them do it on my 340.
I told them when I dropped it off, if it needed bored, that I was not going to be buying any stock stroke pistons. I would be going a total different direction, with a 4 inch crank.
So, I am not really excited about .060 on a motor I am going to invest that kind of money into, with 360 blocks being so common. I know on 340s that I have punched .060 in the past, they have had a tendency to run on the warm side.
I like the idea of the roller cam blocks anyway, but would have preferred to work with what I have.
I didn't even take them the rods, pistons, or heads. Just the block and crank. Once they determined the blocks fate, they didn't bother with the crank, due to what I had told them.
This motor was already apart when I got it, and the old bearings were 10/10, with ZERO wear on the bearings. So I am pretty confident it was rebuilt before, and the rebuilder screwed something up, and it wasn't used. It is a 78 casting.
