About all I'd say is that if it is a running motor it sounds like a good deal even at 60 over in the bore.

If you know and trust the guy with the 400 then I would go that way, especially if the 455 is out of the car and you can't hear/see it run. The 400 looks like a fresh rebuild.
Just my 2 cents. Jim

It would be nice to hear it run.
I bought a 455 short block, looked beautiful (clean), very low miles. Maybe 1,000 miles the guy said. He said he got it from a machine shop, but wasn't sure why it was pulled. Later I found an imprint of the head on a couple of the pistons. The deck was warped on one side and the pistons where chewed on the skirts (detonation?). The short block was Junk. I rebuilt it the right way and that is the engine I have today. I've learned my lesson. Don't trust anything even if it looks good. |
