I just got a DOVE-A block in pretty good shape and want to get it sonic checked to see how far I can bore it. Does anybody have an idea of how much this usually runs? A local shop said they would do it for about $50- $75 bucks.

That sounds like a really good price.
Depending upon the total number of different points checked within each cylinder and how long it take's will usually determine the cost; $75.00 to $200.00 is about the normal range.

$80 to do my 4-bolt CJ Dove Block. mine checked out at 376at the thinnest part. 394 at the thickest part. the backside of No. 4 & 8 is where the worst place will be. i can go 4.500 bore with mine but i just went 80 over for a 557. if and when i do go 4.500 i will probley fill the block up to the WP holes. if you want to go 100 over you can have the pistons made but nobody makes the rings, i got a cadillac part number for the rings if you go 100 over.

There is no possible way the thinnest spots are 376 thousandths thick on that block. Try testing about 1 inch down from the deck where two cylinders are adjacent and see what you have, I'll bet it's closer to .125 at a standard bore.

Not to steal the thread, but just for reference here are two sonic checks on blocks of mine.

The first is a VERY good C8VE block. Tested 1" down from the deck at std bore.
The second is my new Ford Racing A460 block. It's got a rough bore of .020 undersize from a stock bore. It's going to be a 4.600 bore.

His post says "tested 1 inch down from the deck at STD. bore".

David ... you couldn't have been much clearer, LOL.

Keep in mind that there is only about .550 between the bores on a stock 460. So, your thickness number have to leave room for water between the bores. So, if they add together much higher than about .475 they are in error most likely.

I always calibrate my equipment at the top of the bore between cylinders before starting. Not sure how a block could have .400 thick walls when there's only .500 between them. :confused:
