So i am looking to replace the torque converter in my 1972 camaro 307ci with the TH350 transmission don’t have a lot of money ive had several places quote me the part for $600 out of the price range for this part im looking for so ive been looking around and classic industry seem to be the best place to get one they have several torque converter there from B&M and 2 other companies so considering i have a TH350 "not famous for is durability" im wondering if i should go for the GM type same specs replacement torque converter for like 69.99 (don’t think this is a GM part rather generic replacement) or if i should be looking at getting a torque master from B&M with stalls of 2000, 2400, or 3000 from $75-300 does anyone have an opinion im leaning toward the B&M 2000 75$, or 2400 for 175$ on the classic industry’s web site it say the stall speed is between 1900-2100 RPM on all theses models i know better because the sires number indicates the stall on B&M at least i think im right lol

other notes: my engine is not stock but nothing that special edelbrock intake and 500cfm carb with performance exhaust headers in to 3in pipes hp range 190-215 (guess)

 

Really no one huh? anyways after talking to some mopar guys ive concluded since i have a 307ci and don't plan any more major upgrades im going to go with the 2000rpm stall B&M stock peak torque for the 72 307ci is 2400 rpm and i have found out that that B&M recommends that you go with a stall 500-700 rpm under your peak torque range its not going to be a big improvement if any but seeing as i probably have a 2.73:1 rear gear or the 3.08:1 i should look to replace that to gain any acceleration since i have pushed the car to about 140-150MPH couldn’t tell exactly speedo doesn’t go that high pretty easily on open road and im slow off the line not that i race a lot or anything :P

 

A 2000 RPM stall without gears going over 3.08 is considered bad.

This is a good reference. If you're always slipping with your torque converter and it's not locking up then it'll die on you pretty fast from what I'm told. That'll also put a lot of metal in your transmission.

I only understand torque converters in a very limited fashion and I believe a lot of other people do to. I'll have a lot of people try to explain it to me and when I called TCI, B&M and a couple of other places they just laughed at what a lot of people told me.

I'm running a 280 degree cam, 3.42 gears and a 2300 stall in mine and it works pretty nice. I had a 2.56 gear and could just fly on the highways. At 2500 rpm's I was doing 85 and now with the 3.42 gears at 2500 RPM's I'm 60.

 

I think you right about people not knowing what torque converter stall is actual effect and what is correct but if your going off that chart you sent me take a look at the breakaway series its the 3rd one down rear gears listed as 3.00:1 - 3.73:1 i think i do have a 3.08:1 because that was the most common rear gear issued with the 307ci in 72 but ill have to check it out later im not too concerned with 2000 RPM vs stock because the peak torque of a stock 72 camaro 307ci 2brl is 2400RPM and a stock torque converter stall speed is 1800RPM so the i will be gaining 200RPM marginal increase at best
but your right about going to high on the stall the mopar guys said i could go up to 2400RPM stall but i think that would be reckless and would end up with the slippage problem your describing and im going to play it safe
currently i am replacing the torque convert because my stock one is failing making bad noises slippage in cold weather and wigging out at idle current millage is 150,400 miles thanks for the chart and your thoughts

 

Well, if you have a 72 with an 10 bolt 8.5 inch rear you can get the axle code off the passenger side facing the front of the car. You may have to take a wire brush out and knock off paint/grime to get your numbers. Once you have those you can go here to figure out what is hopefully still in it:

Now, whoever owned it might have changed the rear gears on a rebuild and you probably won't be 100% sure until you pull the cover and do an inspection.

No problem, but again that chart is just for baseline. You still have to factor in weight of the car, intended use, etc., etc. That chart is just to get you into a base area to start.
