Engine block machining.

[-83MONTESS-]

i say bore it your self. in class i just started lathe boring and it's the easiest machining practice. depending on the year of the block you can also look into straightening the cylinders because in the earlier production years tolerances were less strict so boring bakes the block's cylinders straight if I recall what my teacher said correctly.

The easiest way to ensure the cylinders are straight is setting a level on the deck surface and levelling it before you make the cut. I have done all of this before in basic machining class but I have a bad habit of second guessing myself especially since this is a VERY crucial part of the build. I will practice on a few different blocks to refresh myself and then start mine and hopefully nothing goes wrong but if something does go wrong I got the guy's number saved. Kind of a bad way of looking at something but something is always bound to happen :x

I told my instructor he main hings i learned so far are deburr and measure 50 times cut once lol

Its definatley harder to put metal shavings back than it is to remove them

If you bore and hone to much, you can always sleeve it. 8) Or bore it .060 if your were boring .040....Everything can be fixed

Good luck.

Any updates? What did you end up doing in class?

Sorry I updated my build thread. I got my ARP main studs installed, magnafluxed it and then the boring bar started cutting inconsistent so I decided not to risk it. by the time the parts came for the boring bar it was time for exams so I couldnt do it. im gettin a good size tax return this year so I will use some to get it bored, honed, and decked. As soon as its machined I can start mocking it up to clearence the block for the extra stroke then start assembling it.
