Better question for Brent. I've always heard that side oilers were pretty thin wall casting, in part due to their original 4.23 inch bore to start with. I've heard .020 is safe, .030 good idea to sonic check first; anything over .030 need to be very careful.
A 428 block typically had a little more meat around the bores and could typically take a pretty good overbore, although all of these old production line blocks were subject to potential core shift.
I heard it all on Al Gore's internet - it must be true. |

Curious what the block casting number is....C5AE-XX or similar. Also as stated above, it would be help to verify a true S/O by seeing a clear pic of the oil gallery on the side of the block and of course the back of the block.
All that said, it would still scare me without a lot of teardown and inspection.

I agree, don't buy yourself a second nightmare.  Have blykins quote you a price on a nice SCAT stroked 428 build. You'll be happier, I promise.  |

It's supposedly a NOS block, so he wouldn't have the crank....it was never a complete engine.
Pairing a 427 block with a 428 crank yields 454 cubes.
Not a bad deal for a NOS block with a SCJ crank.

Hi Brent,
What's the difference between the NOS ( nitrous oxide engine),... lol
Verses OEM (original equipment manufacturer) ?
So, the first owner ordered this set up ?
If it was yours, what all would you do with it, machining etc ?
If it wouldn't cost me two shipments, I'd send it to you and have you go through it.  (if I bought it of course)

If all is as presented and true NOS, that's quite a good deal.
