I was just wondering what the price tag on a 200-4R built properly would be. (US or CAN funds). I just want to be ready when I talk to the tranny shop :-)

Tyler, the 4-speed auto 4L60E comes in late T/A and Z-28 cars, my new T/A has one in it. It is electronically controlled and quite expensive, not your best choice. The ideal (not too pricey, strong enough when built right and fairly easy to install) overdrive 4-speed auto to swap into your '68 Firebird would be the 200-4R. My friend has one in his 550hp 11-second street car and it works well.

Hey, where did he get the tranny? Thinking about swapping my th350 for a 200-4r in my 75 T/A. I'm in Burbank. Thanks.

My Hughes 700R4 and converter has served me well in my GTO listed below, accumulating 40,000 miles (multiple cross country trips) and more than 300 passes on slicks.

As Cliff mentioned, the 3.06 low gear makes it a challenge to "hookup", but the GTO has run a best short time of 1.71 (13.01 @ 103.5) in spite of 3.08 final gearing and a mild performance motor (335rwhp).

Last time at the track with my TH-350 I ran high 7.60's (1/8 mile) with 1.7x short times before I tossed the driveshaft. Replaced the TH-350 with a TH-400, went from 4.10's to 3.55's, went from 3400 stall to 4200 stall, put in caltracs, and put in a 10 point cage. Next trip to the track (probably ~175 lbs heavier) netted a 7.56 with a 1.60 short time; no tuning changes to the engine at all. I don't think the TH-400 hurt me that much.

A friend of mine has a 2nd gen bird with a TH-350 running low 10's on spray behind a stout 455 and somehow it lives. Some are lucky and some are not it seems.

I want the strongest driveline stuff I can afford so that's why the TH-400 went in. One less thing to worry about.

A plain jane rebuilt TH 350 lasted 8 years of racing til I had enough power to get in the low 11s. Convertor sent trash at the same time too. New convertor and a TH 350 from Phoenix trannies cars in the high 10s.

Bowite Overdirves and several others build 200Rs. Lots of those Buick GN guys use them deep in the 10s but then they don't have the grunt of a 455 Pontiac.

Does andyone make a higher first gear for a 700? Seems like there would be a demand for it for torquey motor that don't need a 3.08 first gear.

I switched from turbo 350 to 400 in my 80 bird and don't think the tranny hurt me much either.I did install a 2400 stall at same time and already had 3.42 gears in the rear end.
I did some net surfing and forget but really don't think the turbo 400 is actually that much heavier than the turbo 350.I seem to remember maybe twenty or thirty pounds.
And also doubt it actually robs much more hp and do feel have more piece of mind with it.
I got mine for like 500 or so rebuilt US funds approx.I also bought chevy turbo 400 and used an adapter think made by tranadapt to hook it to my 400 pontiac.It works fine.

I have used both the TH 400 and TH 350 in my 68 GTO drag car. I started with the TH400 and then went to the TH350 with a few other minor mods to the car to get it faster. This was because the 1/8 mile track I usually run at had a time break of 7.50 for two of the classes. My car would run just above or below depending on the weather. Personally I think a properly set up TH350 is ok until you get over 450 to 500 HP.

By the way I solved my jumping betweeen the classes problem. Re-did the engine this past winter. Dynoed out at 638HP and has ran a best of 6.50 in th 1/8 mile. Oh, and I went back to a TH400. Know anybody looking for a race-ready TH350? With the dual bolt pattern case even!

I may be interested. email me with information and price. I am needing anothe tranny, and am thinking of sticking with the TH350, so i don't have to find a TH400 crossmember, change driveshaft and figure out the shift linkage.
