I never said how much HP will be in my V8 but if you have to know that trans will accept just under 300 HP.Can you be more specific as to what V8 you plan to do? Stock 350? 283? Stroker engine with 400 horsepower?
As Dave suggested, that should be a consideration. GM never put a Saginaw in anything too powerful. Some low horse stock 350's, 327's, 283's but no high performance applications.
