Beefy crank main webs
Hello everyone! I'm looking for someone with knowledge of the casting numbers of blocks that can be converted to 4-bolt main caps. I've read 2 articles on the conversion, but the only reference given in the articles is, "First find a block that is condusive to 4-bolt main journal machining." No reference to numbers at all! The block shown has thick flat webs all the way to the oil pan rail. Are there any later model blocks that were built this way?

the early blocks (70-71) are the ones with the thick webs and not all of them have the thick webs. the block casting number is DOVE-A (used in passenger car and cobra-jet cars) but you have to take pan off to see if they have the thick mains or not. i don't know of any late blocks that had the thick mains maybe the D9TE truck blocks but not certain on that one.

85e150, planning on going WAY over 700HP! But right now I'm limited by the 2-bolt block. My next build will start with an Eliminator block, but for now I'll have to use a girdle and call it good.
