Finally, on the fifth attempt, I found a Clevo block that sonic-tested good. The thinnest reading was .131" (just over 3mm). The best part is that I bought it for $50 on Ebay, sight unseen! Just goes to show that they can turn up anywhere.
While at my parts supplier today, I also saw the sonic reports on 2 XE coded 4-bolt blocks. Both tested worse than the worst Clevo I had tested. Both had less than .070" wall thickness. Someone's going to be very disappointed, considering XE 4-bolts sell for $1500 to $2500.
At least I can start my engine re-build now. No doubt I will have a few questions & will be seeking advice from you blokes/girls.

jeez, makes you wonder aye - what is considered to be a good thickness as a base to work from??

tufLTD

Minimum .120" with standard bore. You can allow a bit thinner if it's at the bottom of the bore as it's usually better reinforced, especially if you're going to grout-fill the block.

mine was .220 thinnest and i found it at the scrap yard with std bore , trick said .120 was thinnest he,d use for 650hp with 10 pound boost

tufLTD

.220" thinnest, that would have to be one of the best Clevo blocks around! You sure scored well with that one.

Iguess you forgot about those blocks I offered ?
sold one of them and tested well for the new owner ...
\pleased you found one anyway

i thiunk mine cost $200 to get cleaned and tested from trick and manswetto racing in sydney ,
when your m,aking a $20 g engine , $200 isnt much at all , but geez them $200 bits and pieces sure add up
i was surprised also when he told me as it was heaps thicker than the minimum required

G'day Barry,
I didn't forget about the blocks, it's just hard finding the time to come to Brissy & pull a motor out. I did appreciate the offer though.
P.S.The 'libation' was more like 'paralysation', wicked white man's firewater!Did you milk the fuel from a top fueler & bottle it??????????
