305 to 350/T-tops/5Speed compatiblity

Hey...I've got an 89 GTA with the 305 5speed TPI with T-tops!!!
Looking to modify it or perhaps swap it for the 350TPI. Here's my question...Been getting different stories as to why the 350 and the 5speed were not offered. Is it safe to put a 350 in with the Ttops(FLEX)?Is the BorgWarner able to handle the 350's torque? If I just modify the 305,will the 5speed be able to handle it? Ect..Ect Anyway,hope someone out there knows for sure...

no

dont even think about it! Not in a stock car, anyway. For just a stock 350 tpi
engine, the car should be fine unless you're really stressing it. You'll probably
want to install subframe connectors anyway unless you want various rattles to
start appearing.

The 5 speed is a different story. Those were poor transmissions. I think they
have very good gear ratios, but the strength is just not there. I dont feel
entirely safe with a 5 speed backing a 2.8, much less anything w/ power!

Now, keep in mind every case is different. You may drop in a 350 and run
harder and longer than an automatic w/ hard top. There are always
exceptions to the rule (I'm sure someone will chime in with one), but the
above is what is most often held to be true.

Just hop up the 305 and enjoy the manual and t's.
