Are the merc cranks getting so hard to find nobody considers them a good choice anymore ?

Merc crank and EAB heads is a lot of bang for the buck in my book...[/QUOTE]

I haven't been able to find a Merc crank and it seems the guys that do have to pay big for one. Then have to pay the machine shop to prep them. Shipping is also expensive if you can't find local.

If I happen to find one for a reasonable price, I will grab it.

Remember guys, .125" over pistons (which adds little if any cost to the build) results in a 258 ci engine, while the Merc crank option that is hard to find and evermore costly, only gives you 255 ci.
 
The 49 through 53 Mercury 4-inch cranks are less expensive than the Scat types. There are the early ones with the small bore in the center of the flange end and then there are the ones for the later automatic cars that have a larger bore back there. The last one I purchased a few years back was $250 and it was already ground .020" mains & .020" rods. One that needs to be ground should not break the bank but I would want to know how much wear is there and see photos of the journals if you can't look at it yourself. I would stay away from one that had any damage to a journal unless you can verify the extent of the damage.
 
"rotorwrench" : not to be argumentative, but define "a few years back". I find that these days, when I use phrases like that, I realize I'm talking 10, 20 years, and things are much different now than they were just 10 years ago. Or maybe things are better in Texas; I know in Minnesota, the last couple of Merc cranks I saw advertised must have been cast from silver.
 
Having just gone through this, I would say the going price on a Merc crank that is a gamble is $325, and one that has been checked out by a machinist is $400. Shipping is also a problem and adds to that price.
 
Thanks for all the input everybody. If I find a Merc crank locally for a good price I'll grab it. If not, guess I'll use what I have.
