i was wondering how a t10 would do bolted to a 355 (if it would bolt up)

 

It will bolt up as a muncie or T5 would. Transmissions bolt to bellhousings, and bellhousing bolt to engines. There are dozens/hundreds of combinations of engine/transmission pairs, the interesting part is the clutch/activation mechanism.

Are you asking how long it would last before failing?

 

I second that, all you should need is the correct bellhousing, IIRC 82-83 F-body's could be had with factory T10 4 speeds, so the parts are out there to do a complete "factory" swap. However if you plan on making good power than a Scattersheild from lakewood or the like would be a wise choice, you dont want the clutch to come apart and loose some fingers and toes to boot...

T10's are pretty durable too, more so that Muncies ever where despite their reputation. The 350 in my Nova blew my M20 muncie out twice, then I rebuilt with a thicker front case and M22 gear set but I eventually went with a Mopar A833 which is in the car now. It allows me to dump clutch and grab gear like Ronnie Sox used too lol (7000rpm launch, 7500rpm shifts, 11.2-11.0 in the 1/4)
