Title: looking for a 428 block that is 30 or 40 over
Post by: FirstEliminator on February 08, 2026, 10:23:35 PM

   Hi,
   A few years ago I obtained a 428 block that is 40 over. Had some use, but not too bad. My machinist honed the cylinders to .045 to get them cleaned up. About a month ago, I ordered a set of custom .045 pistons to go with a 4.125 crank. What I realized yesterday is I already had the custom pistons from a few years ago and forgot about them. The best way to remedy the situation will be to find another 428 block. A block that is already 40 or 30 would be preferred. It would be silly to take a standard bore block out to 45 just to accommodate the extra set of pistons.

 Anyone have a 428 block collecting dust?

   thanks,
       Mark

Awww.... Oh well. Hopefully there is another out there. I have access to 2 428 standard bore blocks locally, but taking a standard  right to 45 is grounds for dismissal.

If I couldn't get a .030 plus block i would consider the std block and sell the pistons you have .

I guess one of the ways to gauge whether someone is a real FE guy is when his solution to discovering an extra set of pistons is building another engine instead of selling the pistons.  ;)

I see no harm in having an extra stroker FE hanging around.
