741 Center Section question?

Hummmm, I see. I can not say for sure about the casting number being a good to go number for that power. The 8-3/4 has been seen to hold up behind big block strokers running 9's. IIRC, the 741 is just a hair smaller than the 742 which is a hair smaller than the 489. (Exact sizes escape me right now)

I really do not see a problem, but I also can not say for sure since I have not been there and done that or know for sure of someone that has with that 741 case.
