904 or 727 ?

These guys are the experts compared to me for sure and this is where I come for advice - they helped me a lot doing my first rebuild and as I work out the kinks. I just traded a stock low mile 727 to a guy for an old 904 and 50 bucks.

He was doing a stock 318 and was telling me how the 727 is better and more reliable, and stronger. "Why don't you want to use that 727?".

I was like yes, you're probably right, I just don't want to have to cut my driveshaft. lol
