Transmission is the last major thing to nail down before ordering my chassis.

I've decided to use a (mild) 283 or 327 for power, so to me the obvious choice to back it up is either the Powerglide or TH350. A good friend and former Bucket owner threw me a curveball though and suggested going with the 700R4 because of the OD.

For a T, what would be the strengths and drawbacks of each be?

I'm looking to build a real good cruiser, not a drag car or trailer queen.

Don't rule out the 200R4. if built right it handle up to 400hp. And it's the same size as the TH400. In my opinion, unless your doing alot of highway driving, a TH350 is fine. I'm running a TCI TH350 in my bucket.

The only reason I would use the 700R4 would be if I was doing a lot of HWY driving.

Since the 283 and 327 are better known for their high rpm capability than their stump-pulling torque, I'd go with an overdrive tranny and some lower gears in the rear. That way you get the nice feel down low but still have no problems on extended cruises. Since we have more than once cruise that's 40+ miles round trip, having OD for better mileage is nice too.

40+ miles ain't no highway trip. I'm talking about driving 100+ miles. Tim the Toolman put a 700R in his T and only gained an additional 2mpg. And he drives his T everywhere. If your goal is fuel mileage then you need to go with a Fuel Injection set-up and an overdrive trans, but if your goal is to cruise around town with the occasional light to light blast, then a TH350 or TH400 is all you need.

I had a 327 when I first built my T and I never got it over 3000 RPM which was about 80MPH. Even though they're capable of higher RPM ranges, you hardly ever get it up there. It was a good motor till I cracked the cylinder wall between 4 and 6. Now I've got a 355 SBC with a TCI built TH350 and 3.55 geared Ford 8". At 3500 RPM I'm running about 75 MPH, plenty fast for a 1800lb T-bucket on the street. :)

Good points GT. I sometimes forget how light these things really are. :D

Yikes! That's not the 327 I got from you is it?

Thanks to everyone for the input. After reading your thoughts and thinking it over I do agree the TH350 will be the best fit for what I'm doing. Including "the occasional light to light blast." (me? oh no, never!) :rolleyes:
After all, a burnout by any other name would smell as sweet. :D

hey Photoman, yes that's the one. Remember when you picked it up and I showed you where the crack was. It's between the cylinder with the sleeve in it and and the cylinder in front of it. I think it's either 4 and 6 or 3 and 5. It's been a while since I've seen it. I think it was caused by the sleeve not being installed correctly. If you look real close you'll see gaps between the block and sleeve. The internals should be all ok, but that block is questionable at best.

One other thing that will effect your final drive ratio when choosing your transmission is your rear tire diameter. If you plan on those big 31" or 33" tall Hoosiers or MT radials, your final drive ratio will be fairly tall. If you planning on running the smaller 28" or 29" tires then you final drive ratio will be lower. My T has the 29" Hoosiers on it and with my engine, trans, and tire combo, I can drive about 120 miles on my 14 gallon tank. After drivng 120 miles in a T-bucket, your ready to get out and stretch your legs. :)

im running a 375 hp sbc with a turbo 350 1800 stall converter with 3.00:1 rearend ford nine inch, these buckets are light enough i should have no problem getting down the road at the same time cruise just fine on th highway

Why not be different and put in a 4 or 5 speed instead of an automatic. I did it and it is not too hard, especially if you use a hydraulic activated clutch.
