early engine and late model tranny

[J Man]

I am trying to decide between a few engines for my '24 TT. I have a couple choices, all GM stuff. The thing is I want to use a later 700R4 for better freeway cruising. Who makes adapters to put 700R4s with the older engines. I know one of the magazines did a story in the past cople months but I can't remember which one. Anyone have any ideas. Thanks

I hear they are nice and complete, but not cheap

Best to give us a list of your motor choices, that'll help figure who has the best adapter (if you need one) for the best price.

There is a buick and olds 455, a caddy motor(500 cu. in.?), a coupl pontiac engines and probibly any chevy angine that has been made.

I would suggest getting a 200R4, they can be built just as strong as a 700R4 and already have the BOP (Buick, Pontiac, Olds) bellhousing bolt pattern as well as the Chevy. They're dual bolt pattern. It's a pretty good tranny. 4spd w/ overdrive. Same size as a TH350. I had one in my Henry J and an old Station Wagon at one point. TCI and a couple other places make plenty of kits and parts. If anyone badmouths them I can point them to more than a couple 9 second Grand Nationals that are running them. So they're fine. The thing to look at is that wether you run a 700R4 or 200R4 with one of those big motors, neither one will stand up to the torque if abused in their stock config...

My problem is that I have a lead foot on the highway. my average speed is 80 mph. So I want the overdrive for that. I know of a 305/700R4 that I can get for $100 if it is still there. I figure I can turn around and get $100 back out of the engine, so It would be a free tranny. Are the bellhousingd interchangable between the 700 and 200?

[J Man]

Also what was the last year for the Buick 455 in a production car and what woulf the tranny options be if it is an auto?

[zman]

The bellhousings are not interchangeable. They're part of the case. You should be able to pick up a 200R4 relatively cheap. i.e. less than $100. early 80's full size station wagons are a good place to look. I got my last one out of a '84 Buick Wagon. Even had a good motor in it. Got the whole car for $75. As for the last year of the Buick 455 I believe was 75 or 76. They are lower compression motors. The earlier 70's ones seem to be more desireable. Lot's of parts available to.

[zman]

Oh yeah. Most likely trannys were either TH350 or TH400

A 24 TT???

2.8 GM V6 with 5-speed...light car, small motor and overdrive! http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

(Dirt cheap, too! http://www.jalopyjournal.com/ubbthreads/images/graemlins/tongue.gif http://www.jalopyjournal.com/ubbthreads/images/graemlins/wink.gif http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif)

[J Man]

No offense but the 2.8 is a turd. Besides that I have 3 4.3 laying around now. I decived I wanted a V8 instead and not a run og th mill small block.

Yaeh so, the 200r4 is cool cause you can run full throatal in fourth stock unlike a 700r4 but they are weak good for mild sbc tho. Cant use anything newer than 92 but the 92 pontiac is the best 700r4 and goes against a sbc. the 500 ci cad motor is a good one lots of parts from cad company, like 7000rpm cams and 550 stroker kits useing 454 cranks. you cant run a 700 tho they will burn up unless lots of money. 4L80e are junk they burn up a lot,dont know why just a lot are sold out of the wreaking yards.but a car ap may be cool and you need a thousand dollor computer to run it. I did it in my skoool bus and am pissed about it.4L60e aparently work better. dodge makes a 5 speed manual with granny low and overdrive but adapters are bank. im useing a '04 chevy tran 5 spd its all aluminum and has a built in bellhousing and slave cyl on imput shaft. but i got it cheep. matching engine output to tranny ratios to rearend and tire size is important if it matches youll go a lot faster

if you're gonna run a big motor, just use a (relatively cheap) 3 speed auto that came with the motor originally, and put a 2.75ish gear out back, with tall tires....you'll cruise at 80 just fine, and since it's a light car it will still have plenty of get up and go. Put a switch pitch converter TH400 in it for extra fun.

B&M makes a wot kit for the 700.
most rwd 92 pontiacs are chevies. the 2.8 and 3.8 engines have bop patterns.
454 crank in a 500 caddy?
And please, google run-on sentence. It is difficult to read your post.
