Nice to know a stock looking aftermarket 4 bolt cap set is available.

Cast steel? unheard of impossible its a scam just like Scat's so called cast steel 9000 series cranks and Eagles cast steel crankshafts.

You think I made it up ?
Here is the listing.

BTW, I am a millwright/welder.
I have welded cast steel more times than I can count.
Things that are obviously cast and weld perfectly fine with 7018 rod or Duel Shield wire.
Cast iron can not do that.

IMO, The Parts Place is playing "fast and loose" with their terminology, just like GM did in the 1960's. If GM could get away with calling pearlitic malleable cast iron Armasteel, then why not he "Parts Place"? It is just a merchandising term that sounds cool that they were able to trade mark. It is a high quality cast iron product, better suited for high performance than gray cast iron. It was also used in the Pontiac cast connecting rods. But if I was going to go to all the work of fitting 4 bolt main caps, I would go straight to billet ones.

Even if you’ve got stock factory 4 bolt caps and bolts for free?

40+yrs ago I picked up some 4 bolt caps off a junk yard 428.
I have always planned to rebuilt the 455 from my car with those caps, but maybe they are not worth the cost of machining to fit them to the block?

I do have them in place on the bare block and I was surprised at how close to correct they look and feel. I know they have to be properly fitted, but it really is odd how close to true they seem to be.

If you have a set of stock 4-bolt caps, I would consider using them. It costs about $200.00- $300.00 to fit, line bore and line hone a block in Ohio. Be aware fitting the thrust cap can be difficult with stock caps. Aftermarket caps come wide so they can be faced to match the block. Stock caps have already been faced for a different block. If that cap is already too narrow for your new application, that can get tricky. Believe it or not, I have successfully swapped say the #3 cap to the #4 position if it's wide enough. Then faced that cap for the thrust position. Re-number the caps and your all set. The former thrust cap in the #3 position doesn't know the difference.
