As of now I have a chevy 350 4 bolt out of a 1992 truck I have found a 1984 corvette shell with a "doug nash"(4+3) transmission 4 speed with 3 OD I figured it would be an easy bolt up but a friend said I will have big issues getting the 92 to connect to a 4 speed transmission kinda new to the engine swap only done one basic i figured every chevy 350 would bolt to a700r4 t350 5speedBW, but not a 4 speed ? HELP asap hoping to buy it in two days if the swap isnt to much of a bitch all feedback welcome

Figure out what you're going to do about your torque arm before biting off on it.

Roughly paraphrased into modern English, and applied to figuring out what's wrong with your car:

The simplest explanation that fits all the facts is probably the right one.

Easy bolt up swap to engine with correct flywheel / clutch combo and 4+3 bellhousing
However the problem arises as Sofakingdom notes above because Vette trans does not have regular GM rubber trans mount underneath ext housing ( no trans cross member in C4 Vette ) and you would also need to fabricate something to mount your stock torque arm.






Also the stock 4+3 shifter mounts to the tunnel ; not the trans like normal so you would have to make that work as well.
All not impossible but not a weekend bolt in swap

Also be aware the O/d component of these trans is very expensive ($1500+ ) to repair so do not buy at any price unless you are sure the O/d is working.
The 4 spd part is just is BW Super T10 ; rebuild kits can be had for $120
