Default Auto to Manual. . .

I'm thinking very seriously of converting my White 87 Choo Choo from auto to manual (either 5/6 speed). I've never done this, and am curious what thoughts on this are.

Anyone have any suggestions for brands?

DO IT!

You can go with stock mechanical linkage (which will limit header options a little), or with hydraulic. A different crossmember will be needed if you go with a 5- or 6-speed, a TH350 crossmember will fit with a traditional 4-speed trans (Saginaw, Muncie, etc.), same driveshaft can be used with a Saginaw for sure, I'm not sure about Muncies or Borg Warners (may need a different yoke). The year of your engine will also make a difference in the flywheel you get. If it's '86 or older, you can just pick up a stock flywheel for a manual-equipped G-Body (153-tooth). If you have a newer (1-piece rms) engine you'll need to get one from either an LT1-equipped F-Body, or an F-Body one from the later '80s (i.e. I ordered mine for an '89 Camaro with a 350). For some reason Autozone doesn't list it as available on their site anymore... here's a RockAuto link:
http://www.rockauto.com/catalog/rafr...&parttype=5348

If you're making any kind of power, I'd put at least a T-10 in... then you'll have a slightly stronger trans, but still have the wider gear set available (you can run 2.29-2.73s with the T-10 that has a 3.50:1 1st gear and still turn a reasonable RPM on the expressway... similar to a 2004R with 3.42s-4.10s).

Far as brands, even a stock T56 (later years, post-'93) will hold up fairly well behind a street motor, they're rated to 450lb-ft. For a 5-speed, your best bet will probably be a TKO500, but those are near double the price of a used T56.

I say do it! But I'm biased..... with a small block a 5 speed Tremec would work well.... my intention is to install a TKO600 at some point, muncie is fun but revs kind of high during long highway trips

That's why I mentioned the wide-ratio T10 if he stuck with a 4-speed. I have a similarly geared Saginaw in mine. Even with 2.29s acceleration is still great, and with 28" tires it only turns about 1800-1900 at 70mph... with 26" tires it's closer to 2200.

I had thought about a T10 but, the wide ratio would kill my accelaration with my BBC

No, not much traffic - I live in a small town of about 25,000 and I don't drive them daily anyway. . .Just thought I would enjoy shifting a few gears again. . .haven't had a stick since my '72 Elky. . .and I enjoyed that one, and drove it almost everyday.

I'm sure there will be times I will wish I hadn't done it. . .but all in all, I think I will enjoy having a stick again. . .besides, if I get tired of it, I can just drive the Tahoe. . . Thanks much for the advice. . .I'm going to call Tremac (sp) Monday (assuming I can get out of bed) and see what this is all going to cost me. . .
