With the right bellhousing it'll bolt to your block. You'll need a different converter, different slip yoke, different filler tube, shortened driveshaft and diiferent crossmember. Too many quality choices of 2004R these days to go that route in my opinion, unless it's a sub-10 second, dedicated track car.
its a everyday driver what do you think I should do ? the tran is still working as long as I dont hammer down on the pedal.
I love my 350 trans and I admit that there are "drawbacks or shortcomings." I had a 3.73 gear and stepped back down to a 3.42. I did switch the cross member also. The only advantage is that I have had 5 totally carefree years of banging gears and I only have $900 in the total project. I have my expensive 200 on standby when the need comes for me to freshen up the 350. I have recently purchased another core and D5 converter for a future build.
No drawbacks to dropping the TH350 in these cars except losing the lockup converter and overdrive (4th gear).
If you're rarely above 60 MPH cruising then the 350 is a great trans that's ready for the strip.
Try driving your 200 in third gear to get an idea if it would work for you.

I think i recall an early 80's big buick or pontiac sedan that was a 350 O/D..is that what your referring to ? ..or is it a specialty purpose built trans ? by whom?

Lots of vehicles had the th350c, mostly trucks before he 700r4 was introduced. Similar to the th200c three speed that used a lockup torque converter. Greg Gessler uses one in his fast stage 1 Buick.
Not an overdrive, just a three speed with a lockup.
Lots of super stock racers use a th200. Check out Scott mcclay engineering or one of our vendors. The parts are out there, and there are plenty of builders who can put one together, and have it work long term. You just have to find one.

Those cars were probably 2004r if they were 80s cars.

I would definately go back with a 2004r unless you plan on sub 11 sec and driving it a lot(highway) is way better with over drive imo. The parts are out there you just have to get up with a builder.
I'd you can get by with three speeds a 350 is certainly an option. Lots of parts out there for that, too.
I like a lockup converter. A th350c would be the way I would go if I went to a three speed.
Jim Turner used to run a th350 with a custom planetary of some kind in his stage 2 car.

With a TH-350 you also lose a little low gear as the ratio in first is 2.52 vs. 2.78 in the 2004R. As mentioned, aftermarket planetary sets are available to provide a 2.75 ratio in the TH-350 but that's extra money you could put towards 2004R parts.
