Stall on a Stock 904 Converter?

Well guys...I got it running. I am very surprised how well it turned out. I did a compression check and it was 135 PSI all around. I set my initial timing at 18 BTDC and it idles nice there and no pinging under heavy acceleration uphill. I still need to re-curve my distributor. I have a miss at RPM above 3500, but it goes away when I retard the timing, so I hope the re-curve will fix that. I am going to get the carb tuned by a carb shop here. I'll have them put in the correct power valve and jets. I'll leave that to the pros since my experience with carbs is limited. The plugs are a bit too white for my liking. I changed the diff fluid and found out my gears are 2.76, not 2.71 after cleaning all the crud off the ratio tag. Watch out...break neck launch hahaha. But really, it drives great and was a big step up from before. Thanks everyone for all your help. I might just keep the rear end I got. Cruises the freeway under 3K.
