The pass car blocks may be opened to 4.250 with a narrow safety margin. This may be due to core shift/rusted bores or even overboring damaged cylinders. Sonic check to be 100% sure and then be careful with the overbore. You may or may not get a 440 sized piston bore, but a 426 wedge piston size is abit more do-able. Safety is the key. Think about it when you add more compression/cylinder pressure, rpm and maybe bolt on "power adders". Things CAN get disasterous if the motor lets go! If you really want a 4.325 block, buy a used 440. You would be gaining even more overboring it! 413's are great, don't get me wrong, but for what you want to do 440's would be better. It's a gamble for the 413 due to it's age! Good Luck!! "Stupidity is Ignorance on Steroids" "Yeah, it's hopped to over 160" (quote by Kowalski in the movie Vanishing Point 1970 - Cupid Productions)

If you need the cubes, lengthen the arm (stroke), but don't go crazy (undersquare)with it. Thanks for the input BG. Last edited by HYPER8oSoNic; 08/08/10 05:42 PM.

Yes, it isn't recommended to go that far overbore, and you should sonic check if you are planning anything over 4.250 with a 413 block. However, I have two 413 industrial block based engines that are 4.310 bore that have been running since 2004. We have been switching and freshening these engines every two years. I know that most max wedge stock eliminator cars, like mine, are using the 413 industrial block. I don't think that you would ever want to do it with a passenger car block. We just built a 4.250 bore 413 street wedge this past spring that is in a 63 sport fury convertable and running great. That is our experience with these blocks.

Not doubting, just curious how much thicker they actually are. Also, are they any heavier in the main saddle area, as this seems to be the achilles heel of RB's, with cap walk and cracking in that area. It seems that this would be the bigger advantage of an industrial block as it seems most BB Mopars cash it in because the cranks are dancing around at high horsepower, and not blowing holes in cylinder walls. Any pics of an industrial block? I know that they have a ton of extra webbing on the sides of the block as compared to a "normal" RB.

Or the numbers on the side of the block juxst above the block plugs. Sometimes the numbers are stamped in back of the engine. Not a bad find at all!! GOOD rugged block!!
