Now that I've had time to look it up, here is a more comprehensive answer. 413: 4.19 bore by 3.75 stroke, 4 bbl carb, 340 HP@4600 RPM, 470 ft lb torque@2800 RPM. Hotter version gave 360 HP@4800 RPM
426:4.25 bore by 375 stroke, 4 bbl carb, 365 HP@4800 RPM, 470 ft lb torque@3200 RPM. These are specs for '65 engines. Previous 426 wedge engines had dual 4 bbl carbs and were rated at up to 425 HP with comp ratio up to 13.5 to 1. Hemi engines are the same basic 426 engine with the Hemi head and dual quads rated at 425 HP.
I hope this answers your question. Either way you have more than enough HP to break those axles.
Good Luck
