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.
