If it were me, I think I would leave the stock axels in. That way they are the weak link instead of the transmission. I'm sure an axel is cheaper to replace then the trans.

Others are pushing well over 400rwhp on stock and haven't had a problem.

How's the spool on the 30r? I wanted to do a 3076r on stock motor but don't want it to be overkill.
