700r4 help

hey guys, have been looking for a good 700r4 core for a long time and havent been able to find one, finally found one online, getting ready to go look at it pretty soon. I called the guy, can tell he doesnt know jack about cars, I wanted to know what year the trans was because im only interested in 87-92, the guy said he got the trans already pulled and doesnt know what kind of car it came out of, also he says there are no numbers on it, so what I asking for help on is it anyone here knows how to ID these transmissions without serial numbers.

red, this is outstanding info, thank you.

UPDATE 4/11/11

Built With:
87 "K-Code" 700r4 core
Monster Transmissions "Mega Monster" Rebuild Kit
AC Delco Five Pinion Planetaries
TCI Constant Pressure Valve Body
Carb TV Kickdown Bracket
B&M TV Cable
B&M Lock-Up Converter Control
Corvette 2200 Stall Converter W/ upgraded Thrust Washer (4130 Steel)

Total Invested: $2025.00 (not including paying to have the drive shaft shortened, I haven't done that yet)

Sounds like it will survive a heavy foot!! What rear end ratio ?

right now just the stock gears (not sure on which ones they are for sure) but after the trans itll be getting 3.73's and a posi.

man as much as having an overdrive is nice I sure dont like TV cable transmissions. Hope it works out well for ya.

Somebody stickied a link I posted about TV setup in the engine & driveline section. Check it out if you haven't already.

i got the b and m stuff, we used it in the 70 chevelle and the thing works great,when i get it all together ill give you guys a complete parts list in case you wanna try it, i NEED that overdrive with the way gas has gone up...i might leave the stock rear end gears in it too since its a daily.

with a 700 first gear is so short that you dont need much gear to get off the line. 3.42 or 3.55 is where id stay at

i thought about 3.42's, i was going to run them if i ended up putting in the 454, but with gas going up like it is i kinda put that off, but i still might just go 3.42s anyway

Unless you do a lot of drag racing, you dont need that low a gear. For a street car with a big block torquy engine and an overdrive trans a 2.73 will work fine. Sure, a 3.08 would be even better. Its these small block cars that need these real low gears because they are not as torquy. JB

yeah, i was hoping to use the big block but for a daily in a car that gets a lot of miles i think its best i stick with an sbc...i got a 010 casting 350 4 bolt motor im rebuilding so ill probablly stick with that. The set up im running has pretty good low end torque as it is, so it might be ok, rearend needs rebuilt anyways though, axles at the minimum.

That old saying; "you can't have your cake and eat it too" ,or if ya wanna play ya gotta pay!
Our fun is costing way too much these days...

When it comes to good gas milage, the way you drive has as much to do with it as to what engine you have in it. When I first got my 540 put in I drove it down to Elizabethtown and back on I-65 to break the engine in and got about twice the gas milage I expected to because I took it easy, I only got up to 70 once or twice.
