I have been talking to a mechanic lately about rebuilding a Cleveland V8, he suggested not going more than 30thou with the Cleveland as in his experience the Clevelands tend to run hot if taken out any further than 30thou. Has anyone also experienced this with Clevelands, as the block i was interested in using is already 30thou up and may need a clean up.

I have heard that of Windsors so your mechanic is probably right. 40 though would not be unrealistic IMHO but 60 might be stretching it.
He has nothing to gain by telling you this. Cleveland blocks are still cheap and plentiful so it might be worth trying to source another block unless it's a block with a significant engine number such as a 351 from a GT or an ESP. If that's the case you could spend the money and get the bore walls sonically tested for thickness to see how much more boring it can take.

clevos have a thin wall bore, i reckon all the iron got used elsewhere in the 11ty hundred lb block and there was none left to put a decent bore wall in it LOL.

I just had 2 Clevo blocks bored to 40 thou, but I had ultrasonic tested them before hand. There are many stories of the blocks being off set cast, so they are thin on one side of the bore, and thicker on the other. I run straight LPG that obviously is a dry fuel and burns hotter, so I was concerned about going 40 thou, but all seems good. My blocks did ultrasonic test real good though. I did not want to go the "Clevor" way, I would of sleeved my block before buying an aftermarket block, even though price wise they are very competitive!

Nice post! You are certainly not wrong there! To the OP, what era is your block? AS XD/XE had the "pillow block".

The main reason i posted this topic is that i am building a 1970 XW Falcon 500 Sedan (No not a GT mockup). I dont want to go through building a motor and then rock up at VicRoads for registration and to be told that your motor is date coded ie 1976 adr27A (from the engine number) and you must comply with the regulations of the day. A similar thing happened recently to a bloke who put a Commodore SHORT motor (5 Litre 308 )in his Holden HJ ute only to be told its a Commodore motor and it must comply with the pollution laws that apply to that engine. See where i am coming from? If its pre pollution a lot less of a pain in the behind. That is why i was looking at rebuilding the early block (1972) no pollution instead of the the later 1976 block?
