Freshening up my 401

[dwg86]

My 401 started knocking, sounded like a high knock cylinder knock, and I found metal in the oil. Number 8 piston was scuffed and cylinder is a little scored. I am already .040 over and I don't think the cylinder can be honed without being to big. So as I'm looking at my options and replacing parts, I thought I would share a few parts that I'm finding. Johnson lifters are made in USA and can be purchased directly from them for $4.70 each at http://www.hylift-johnson.com

Wiseco sells off the shelf forged pistons (street pro tru forged) at .030 and .045 over for $410.00 from summit. That includes pistons and rings. They also make them for the 360. http://www.wiseco.com/Catalogs/ProTru/CompleteCatalog.pdf

Not sure if this helps or if you are debating such, but I have been running around with a 0.060" over 401 (413 cid) for many years. I think it is 12 years now actually. I concentrated on keeping it cool to limit cylinder distortion from excess heat and the thinner walls.
