Default Transmission choices...

I'm putting a GM crate ZZ383 in my '72 Monte (about 3500 lbs)
It is advertised as putting out 400-450 lb/ft from 2000 rpm upto 5500.
15" rims, cam duration is 222/230 I'd like to put a 700 R4 on it and have read here that I will probably blow it up. I plan to keep this car on the street 95% of the time so the OD would be nice. Any suggestions as to where in Canada I can find a reputable builder for my core or a bullet proof trans off the shelf, or do I have to get a TH400. Any other suggestions, I realize big dollars may be involved, so any tips on getting the best value is appreciated.
btw has anyone bought from Monster transmission on E-BAY?

If money isn't a big issue, the 4L80 would be the way to go since it's turbo 400 with OD and pretty tough.

Isn't the 4L80 computer controlled?

Yes they are but you can correct that. You can use a stand alone deisel trans controller or you can go to a full manuel valve body with a good rebuild kit. I personally have a Buick Grand National 200-4R trans in my El Camino with manuel toggle switch for the converter lock up, they are running these trans with 1000HP turbo buicks. It cost me about $800.00 for the full beef up. But back too the 4L80. Here is a site that sells all the parts to convert to a manuel valve body, also TCI sells one already built with the conversion. After looking back on my original recommendation, i should have suggested the 200-4R it's easier and cheaper and doesn't require a computer.

I think the 200R4 is the way to go, thanks for the advice.
I found a 4L80 here in Canada for $2000 but private sales over the 'net makes me nervous. I'll start looking for a 200R4 from a shop.

Default 200R4

Summit has the 200R4 for around $1760 and it is built by Hughes Converters and Transmissions.

theres no reason 700 shouldn't hold up to your zz383. just need to get a good "street strip" version of the trans. be sure it has the "torque-drive" input shaft/drum assembly (heavy duty) and if you want bullet proof, get the upgraded planetaries. Get a good converter such as a transmission specialties 10" xtra low stall. i believe they say its around 2500-2800 rpm stall. You can decide if you want lock up feature or not. If you can hear the cam (moderate to large cam) id say non-lock up myself. To me it pulls the motor down too much unless you got some gears in the rear. (it should pull the cruise rpm down 200-400 rpm lower than if you went with a non-lock up.)

I know a guy that has a 700 behind a zz383 crate engine that he swapped heads to dart 230's and put a 6-71 supercharger on. Has a transmission specialties low stall-xtra heavy duty blower convertor. He took the car to local 1/8th mile dragstrip and ran 6.44 pedalling off the line because his wheelie bars were too high after he changed to 32x15 slicks from the DOT 31x18.5 hoosier tires.

heres the car. its an ex super gas 9.90 index drag car that was converted to be street legal.
