Block inserts question

[Jerry in Shasta]

Can I take my block to a local machine shop and have them line bore it to
take the main bearing insert shells?

Thanks JB

I'd consider that pretty risky unless they have done it before.

i would only use an experienced shop ............

Not only does the bore have to be right for the shells, the crank-to-cam spacing has to be correct to. Make sure the shop can get this spacing right.

That's one reason I like my Kwik Way LBM. It locates the crank bore according to the cam spacing and the centerline of the block. I have bored about a hundred blocks for babbitt and inserts and have never had more or less than .002-3 lash at the gears.

Like above, risky business unless the shop has done it before. I had an experienced machinist to instruct me on more than one block before I did one on my own. Lots to watch out for and lots to go wrong that can ruin a block. I have a couple I saved that came from shops like you suggest and show the nightmares to potential customers.

BTW, there are nightmares that come from your area too. From people who should know better but don't care. All $$$$$$$
