BRF vs. non-BRF?

[scojack_2001]

I have a question. I know the BRF 200s were in all the Turbo cars, but whats the difference between the two other than the servo, valve body, and governor?

The reason I ask is that I have a spare, built low-mileage 200r4 out of my totaled WH-1, and was wondering if the trans would bolt to a SBC 350. My brother has a 72 Nova and I was gonna loan him my current 200r4 when I put the built one and stall convertor in my GN. Ive seen it done in one other Nova, and the owner said they were all BOP & Chevy housings. He also said it would bolt right to the 350.

Now my second question is, how much could a non-BRF trans take? I dont want to sell the original trans to my GN, but the T-350 is killing my brother's gas mileage. Could we build a standard 200 to take 400 ft. lbs.?

Just kinda thinking out loud here.

Any advice appreciated.

All of these transmissions are limited in stock form regardless of oem calibration.The brf has the largest oem servo and will outlive a kt in the same hi perf application because of calibration.I would rate a stock brf 2004r as new from the factory at being capable of holding 300 and 350 ft lbs of torque for 25,000 miles if its lucky.no one however has a brand new transmission where all parts have not had cyclic loading ,and heating and cooling cycles that have not unparralled all the mating surfaces of hydraulic components etc.or induced wear patterns that degrade component life and performance.I know the trans will bolt right up to your sbc but I would without question use our valve body recalibration kit.its a proven performance enhancer and component life extender.

Thanks Cris for the quick reply. I would at least assume a the trans would be fully rebuilt, if we went with a non-BRF core. A shift and good parts would help too? We have a local 200r4 builder so thats not a problem. Would building it to BRF-spec help, or just be spending money where it isnt needed?

Now we just gotta get a new cam and convertor setup figured out.

the brf would be a great choice but if you use a non brf just get a brf servo .i have recal kits with brf servo without or with a billet one.
