Internal or external balance 406 sb???
I am looking at going from a 350 to a 400. Lost the 350 to rod bearing failure, and rod journal on crank. I know I can swap alot of my parts to the 400, I was at aprox. 475 hp with the 350. With a 406 making aprox. that much hp or more,not mention the increase in TQ. Will the stock 400 crank and rods handle it? I was looking at getting a crank kit, cast crank, and I beam rods. Should I get an internal ballanced kit? This is a street car and will not see much track time. The 400 I can get is a two bolt main block. Any other imput,help,or advice will be greatly appreciated.Thanks
