28 spline or 31 spline

just out of curiosity, what made you go with the 393 instead of a larger displacement stroker? i haven't decided 100% on what i'm going to do with the engine but i'm seriously leaning towards the 408.

why does the standard need the 31 spline? while the AT does not?

I've known a 12 second car and a 13 second car to break (stock) 28 spline axles. It all comes down to how sticky your tires are, how hard you launch, and maybe what the price of eggs are in China, I don't know. You certainly don't need 500hp to break stock axles. You could have an 800hp, 10 second car and launch like a and not break the stock stuff, or you could have a 300hp, 12 second car and dump the clutch at 6K on slicks and snap them like twigs.

Disclaimer: I'm exaggerating, but you get the idea.

that makes sense about not wanting to clearance the block. if you're willing to dish out the details, what does the rest of combination look like? you mentioned that you'll be pulling 500+hp? sounds good to me!! if you'd rather not post the details but are still willing to talk about what you've got feel free to email me at jdirig@cox.net
