Pins are .250, came with the Mahle plug kit. I have some other Dorman PC-725-25 that appear identical.
Looking at Beanheads picture it appears I may have been looking at the wrong holes. The hole with the dowel k. That picture only measure .245 and the pins won't fit but if I need to clean them...
I'm working on building up my 470 stroker and I'm running into an issue. Some of my cylinder head alignment dowels are falling through the holes in the engine block. What's the recommended procedure for getting these to stay?
I actually just tore down a 72 400 engine and the valve covers were in good shape. PM me if you're interested in them and I'm sure we could figure something out.
I agree. However, I was measuring the diameter of cylinders that were already damaged. Once we got the shortblock to.his shop and started taking pistons out of holes, everything was checking out at spec, with the exception of the cracked cylinders. The cracked cylinders were within spec at the...
As an update - I took the shortblock to the guy that built it. We could not find any good reason that it failed. No evidence of anything out of spec when using tools much more expensive than what I have in my arsenal. In short, looks like I have bad luck and the block was a dud...
However, I...
I try to be realistic and realistically I may have **** luck... but it definitely could be worse as you said. I should hopefully have caught everything early enough that it can be re-used and breath new life. Just gotta put in the due diligence to figure out the best course forward. That means I...
That is a possibility and I'm not dismissing it at all. I'm not trying to blame the builder but do want to find the cause so I can learn from it and if it was someone's error that it gets corrected amicably. Even if I just learn that sometimes you just lose, life sucks, and I bought a **** block.
I verified thrust dimensions and I'm getting 4.371 with both calipers I have. Granted, I'm using a bore gauge/calipers and not an ID bore micrometer.
Also attaching pictures of the wear on minor/major trust walls for a couple cylinders to see what thoughts are on those. Pictures didn't come...
I can focus on thrust dimensions at lunch.
I corrected my typo on my previous post. Pistons are 4.375 ( http://store.440source.com/Platinum-Series-Pistons-4375-17-Dished/productinfo/5070/ )
I put my ID bore gauge on all the cylinders ans came back with measurements ranging from 4.371 to 4.375. There were some slight deviations with some slight out-of-round cylinders, including the ones that cracked but I'm not certain if that would be a symptom or a side-effect.
