I will be (sadly) letting this go shortly after the new year. I do not know anything about it other than the obvious. I will post back to this thread as soon as I have details.

 

what?

 

425 Olds?

 

How much? I am interested,& I think you are close enough for me to pick it up.

 

His pictures are named 455 so I suspect that's what it is.

 

Either way it appears to be a forged crank.

 

Here is a little more info: stamped # on block [38M234228] C heads.I have been very busy with the holidays & as soon as possible I will get more details & pics. Happpy Holidays to all

 

Good news & bad news; first the good news, I have finaly had a chance to check out the engine and as it turns out this engine is a steel crank w/4.25" stroke & '68 up flywheel flange. The block casting date is 360# with "F2 68" on the back. The "C" heads have a casting date of 360# & 363#. The bad news (or not so good news) is this engine had been partily overhauled, rings, brgs, gskts & due to some unfortunate circumstance it spun a rod brg & damaged the journal. I have not had a chance to measure it. Here are some pics of what I have seen.

 

I'm still interested,so let me know the price.

 

Here are some more pics. I failed to mention the engine is std - std/std.

 

As I suspected the journal has considerable wear (.050" +/-) and will require welding, it's very unfortunate.

 

That line on the piston is where it came up & smacked the head.

So what do you want for it?

Is this show and tell or are you going to put a price on this thing already. You have been asked several times for a price and all you give are more pics. WTF Jkaz

 

What are the casting numbers on the crank? I saw a piston smack a head like that once before. A guy had a 425 engine and thought it was a 455. He replaced one piston with a 455 piston. Yep, it had a knock after that.... once disassembled the piston looked like yours. I traded him a running 350 and got his motor for parts. John
