I have had this engine block for about 20 years and decided to build it. upon looking at it I realized that it has a sleeve in the no. 1 cyl. how bad is this for a performance build ? ???? Im about to go get another block arent I ????

If it was done well, there should not be a big problem with a single sleeve. Depends on how much performance you intend to put in it.

Agree with Brain M. Good sleeves are fine with performance. Cylinder sleeves are used in all kinds of motors, from aluminum small blocks to inline 6 cummins turbo diesels.

If your worried about it, have a machine shop check the sleeve and see if it was installed right. I would go for it.

I have ran as many as 3 sleeves in my cleveland race motors. Not a problem, and that was in a motor that ran hihgh 9's in the qrtr. If it was installed right, that hole will be stronger than the other 7.

As for the aftermarket cleveland block, there isnt a true aftermarket cleveland block out there.

You can bolt them on a 9.2 deck aftermarket but you'll have to work out the water routing issue and the rear manifold to valley seal. There is no aftermaket 351C block available anywhere. We're having a huge debate about producing one over on the 335 forum.

Has anyone here ever seen a sleeve done "wrong" or is that just a CYA blanket statement.... Really curious... I have never seen one done so I cannot say how it could be done right or wrong... The process sounds complicated enough that if someone new how to do it (see *machinist...) it's a good bet that it would be done "right" or the car would never have ran right afterward... Is that a good summation?

Yep...when I first was learning how to do machining, I put a sleeve in wrong. Wrong size sleeve, broke into water and after the sleeve was done (again...wrong) it seeped a little water into the oil.

Lesson learned, but again, it's not hard to put a sleeve in the right way if the machinest has even a half ass knowledge about how stuff works.

Supposedly the Aussie blocks have thicker main webs and less core shift around the cylinders. I haven't been able to get a straight answer yet.
