HINKSON AUTO

This a perfect example of why plate honing is a m must along with using a good hone.

This engine is a 604 GM crate circle track engine I think this block was honed once as the bores were 4.0015 Had an old time racer 78 years old that raced for many years witness this and was amazed.

This class can only go with a custom .005 over piston made by Mahle, After bolting the plate on and making a couple of strokes with the 412 stones it was clear that there was a reason the ring land between the 1st and 2and ring shows signs of carbon or poor ring seal.





You wouldn't see as much distortion with a Bowtie, Dart or World block, But I will say the getting close or at max bore on one these block you will see distortion. It does make a difference studs VS bolts.
