does anyone know what the identifying marks are for the universal 2004r? is there a specific pan or bolt pattern on the bellhousing?

The Chevy trans. has 12 bolt holes on the bell housing.The May 2003 Chevy High Performance mag. has an article on beefing up the 200-4r trans.

thanks guys. a buddy found me one in a salvage yard and picked it up for me today for $60. he checked it out and said that it spins over and there are no obvious problems with it. now i gotta pick up my lt1 and i will be a little closer. thanks for those links.

lt1/200
my kind of combo

hey fast, did you build your 200 or did you have someone else do it? what stall are you using and how are those 4.10's on the highway?

I simply used a transgo full-manual kit, GN servo and a hughes GN converter (11" ~2500)on a rebuilt unit, would like to upgrade like the CHP article someday soon [the little 333 w/ the comp 286 needs more stall so I'm going PI Vigilante when $ available, have one in the 94 and it amazing]
w/ the 4.10s it's great

wouldn't recommend 4.10s w/ the torque an LT1 will make, you'll need a 4link to hook it :eek:

btw, ODB 1 cars have a problem w/ stalls over 3000 causing them to not shift, have another 200-4R that is my backup for the 94 Z if it won't shift or if the "396 LT4" kills the 4L60E

i am still debating on the cam but am leaning towards the cc 224/236@.050 w/1.6rr's. probably wont need over a 2600rpm stall with it and dont plan on a lot of strip time. i had a 69 years ago and it was stolen and trashed so i am just looking for a nice driver. my old car ran 11.20's but wasnt streetable and this time i want something that gives me what i have with my 95, just a little quicker.

the extreme grind? very popular w/ the 4th gen crowd, I would (and always do) recommend comp "R" lifters (if you can find them, also very popular and seems like always out of stock)

using odbI or odbII or carb?

i will be using obd1. i want to try and keep it as streetable as possible and will probably get antique plates so no inspection so i can get it tuned for the best all around performance.
