455 / 2004R combo??

[hawaii69gs]

I understand that most of the turbo buicks (factory) like the GN's came with the 2004R trans. (If I am wrong, my apologies)
If so, I am wondering if those 200's will stand up to the torque of the 455?
Almost stock build daily driver. Gonna attempt to squeeze the two into a 65 Chevelle.
Thanks & Aloha,
Scott
Been trying to find a knowlegdeable source here in Hawaii, but no luck yet for an affordable rebuild of one I have in storage.

Usually, the 200-4R will hold up nicely behind a stock 455. Remember that a 455 can create a lot of torque, and if you plan on thrashing it then you should have it rebuilt to high-performance specs.

Also, be advised that not all 200-4Rs are created equally. The ones from the Grand Nationals were stronger than the 200-4Rs that you'd find in more generic applications. But it sounds like you have one from a GN so you should be okay.

The 200 is a great trans. Plus it is about 3.5 inches shorter overall. Sometimes that helps. my X frame needed it.

Just put one behind a Nailhead in my 65...here:

T400 is almost indistructable stock, and is the stock trans for the 455,s. for performance a T400 with a lower 1st gear
will give great performance out of the hole, with the stock rear gears. checkout this site for more info

TH400 is definitely awesome. isn't the TH400 a 2.48 first gear? The 200 is a 2.74 and the 700 is a 3.06.

Plus, the 200 has a .67 OD. Now that is cool.
