400 sbc block
I'm needing some advice. I have a 400 sbc engine that has been bored 060 over to 4.185" with a 3.48" forged sbc crank. I ran it in bracket S-10 without problems. While getting it ready to put in a altered chassis, dropped pan and discovered small pieces of someone else's dipstick. So I tore engine down and now don't know whether to rebuild it or not. I want to put 12.5 or 13.0 cr pistons in it, and make about 625hp, but I am worried about thinness of cylinder walls. I should also mention that it's a 2 bolt block without block filler. Thanking everyone in advance for their advice.

Filling the block does nothing to make the webbing of the block stronger and with the bigger housing bore and cylinder bores it weaker then a 350 block also 400 decks are weak as well. 400 blocks have a wider bolt patterm on the main caps making the caps weaker then a 350 block. |

Thanks Hink for your info on the 400sbc block. I didn't know all of that. I have several 4 bolt 350 blocks, I'll rebuild one of those instead. Thanking you again. csx8506

You could always go with a dart shp block.
