Trade 833(plus $200.) for a 833od?

Thanks for the replies...I think I'll keep my 833 and purchase an 833od. My tranny isn't a matching #,so I didn't think it was a big deal...but it seems like the close ratio is in more demand(more rare?)...I believe the od that I am considering is a cast unit...should be more desirable than an aluminum unit?....If the price is right, I might consider aluminum since the car is going to be a cruiser(with a few WOT) Thanks,Dan ps:Manitoba is the province that borders North Dakota and Minnesota.
