Does it need to be modified to fit into a 71 camaro? and what is the most h.p. and torque it can handle?

I think you have to shorten the drive shaft and to fabricate a new transmission bracket.
(Perhaps you could modify a TH 400 crossmember).
Look for a setup to use the look up converter.

Several good articles on this. HemmingsSept/Oct 2000, "bulletproofiing the 700-r4, pics and good tech stuff. Also look at Swap into OD, Chevy HP Jan 2000, explains all the shaft differences, mounting, and part nums you'll need going from t400 or th350 to either 2r or 700.. ALSO, search this web site, these guys have good disscusions on this topic for 2 years. Good Luck, mine is being built now to replace my th-350.

The 700's will handle about 450 ft. lbs. with all the right parts. A 2004R can handle much more (700+ h.p.)when built right and is an easier swap. I had one in my 72 Camaro. It was built by Bruce at http://www.ptsnctb.com/.

If you have a poweerglide, TH350, or 3/4 speed manual it's a direct bolt-in with a TH400 crossmember. The stock yoke and driveshaft remain the same. If you currently have a TH400 it's a direct bolt-in and only needs a yoke/driveshaft from a 4 speed or TH350 car.

Give Bruce a call at (916) 739-0510. I had over 600 h.p. in the 72 at one time and the trans worked flawlessly.

A guy I know says he has nothing but trouble with 700 trannies. He finally went with a th400. I want a 700 but am not sure how strong they really are. I know people out there say they race them with loads of power but what do they have in them to make them last?

Just to save some time, I will again state that a HIGHLY MODIFIED R700 CAN live behind a max. of about 500HP and 500 ft.lbs. of torque but THAT IS ALL.

A 2004R from Bruce (WE4) is good up to a MAX of 650-700HP and THAT IS ALL.

The reason the 2004R can be built stronger is that BILLET STEEL components are availble for that tranny from people like BRUCE. The R700 doesn't have that type of parts availabilty yet (billet steel parts).

If you plan on running slicks and ARE at the MAX limits as specified above DO NOT EXPECT the tranny to be able to take this type of abuse long term.

The reason I know all this specifically about the R700 is that I broke that tranny four times already with a 650 HP setup. Failures ranged from a SHATTERED input drum to 3-4 clutches becoming toast. NO ONE makes a R700 tranny at this time that will live in this type of environment especially if you do as I do and use your car as a daily driver.

sr71bb - Bowtie Overdrive http://www.700r4.com claims the tranny will live forever on 11.00 or slower. He said he has been doing these trannies for years with no problems at all. They do come with a guarantee. I ordered 2 to go behind a 502 in a 67 camaro and a 70 chevelle. I will let everyone know just how well they hold up.

I would be willing to BET ANY AMOUNT of money that it won't live behind mine. The only problem with a warranty is that unless the guy is local, it is just to much of a hassle shipping the broke tranny back and forth.

Please keep us updated as to how yours holds up. My guess is that in 6 months or less the clutches will be toast but I could be wrong and I REALLY hope I am.

If you put that BOWTIE tranny behind a stock 502, I could see that it might possibly hold up because that still is just 500HP.

a 200R4 is built for a light weight car.it isn't ment for the heavy weight cars like a camaro,chevelle,ect.... that's why they made the 700r4. also if you do decided to get a 700r4 buy an 87 up trans.the old one's are **** !!!!!!

The Buick Grand Nationals ran 2004R's, not 700's and they're at least as heavy as the Camaro is. The 2004R will DEFINITELY take more abuse than the 700 when both are built correctly.

Now children lets not fight. what ever works for you use it. If you can get a real guarantee from a local builder use what he builds. I have never used either one I always stuck with a 400 they gave me no trouble but mine weren't street cars

Actually OGER,

It is not that we are really fighting over this, it is just that there are some of us that have spent tremendous amounts of money and time on solutions only to find later that they WILL NOT work. I have a great tranny guy here locally in Larry and we both had to go thru a pretty painful learning curve of a high horsepower 700R application. He warrantied the tranny FOUR times but we both came to the same conclusion, that being that the 700R was the wrong choice for a 650HP application. If someone still chooses to try and make a 700R work in a similiar situation, my sincere hope is that something can be learned from our experience. I am especially sensitive to those that can not afford the cost of a misapplication and that is why I share the info. I never really believe the claims of a vendor until I try their product out for myself and more often than not, there are some "GOTCHAS" somewhere!!!
