I was wondering if anybody here has successfully mated a 2.3T (with the 5.0 Bell housing adapter) to a 302 T5 transmission? From what i can see the only difference is the diameter of the input shaft. If I were to get this milled down would this be a proper solution for this issue?
If this union has been successfully completed by anybody on this site, please let me know. Also, if you have had the shaft milled, what is the OD dimension that it needs to be resized to?
TIA for any help you can provide

Matt has one in his car, we just put a bushing in and didn't have the shaft resized. Having the input resized is a more "proper" solution though. I've got a 5.0 trans in my SVO as well.
4cyl input is 15mm (.590), v8 is 17 mm (.680)

What bushing did you use? What are the potential issues with using a bushing instead of the bearing? Is it difficult to replace the bearing with the bushing if i already have the motor sitting in my car?

The bushing is available from the Rapido Group (google it). The downfall is they typically don't last quite as long as a bearing.
Replacement is no different than replacing a pilot bearing...pull one out, put the new one in.

I decided to have the shaft turned/milled (same thing?). The only problem I have now is that they shaved off the case hardening that encased the end of the shaft. The guy at the shop to me that he estimate the hardness to be either 50-60 Rockwell. So I am currently looking for a shop in my town that does heat treating. I have potentially found 2 different shops who both want around $60 to heat treat the shaft. This cost plus the cost to mill the shaft brings my investment in this shaft to $125. I can justify this cost being that I was able to look up tag number on my tranny that i have and it is a M-7003-Z 1352-249 T-5 WC, which will handle up to 330ft/lb.
I can't wait to get this car on the road, barring no serious hindrances with my little "flywheel" fiasco, it shouldn't be long now.

The torque ratings crack me up...we've pushed over 450ft/lb through a 2.3 box that's rated at 260 or something.

Also does the different input shaft length matter?? V8 T-5's are 7.18 long and the 2.3 T-5's are .23 longer at 7.41. I didn't know if the .23 is a big deal or not.

The adapter plate is about 3/8" thick which offsets this difference.

hi Stinger
1. Do you happen to know the OD of the V8 5.0 piolit bearing, or the ID of a 5.0 crankshaft bearing hole?
2. Has anyone use the trany adaper set up in a Merkur?

No, I don't know those dimensions off hand. I'd just go buy a 5.0 pilot bearing for cheap and measure it.
Not sure if anyone has used one in a Merkur. I know downpipe clearance would be very tight it one since the bellhousing is larger on a 5.0.
