Tourque converter

I have to rebuild my trans and replace the converter. It's an 1100 stall in it right now and I'm at a loss for what one to put in. It's a 289 with a mild cam (edelbrock performer plus) with a 4bbl intake and headers

March your Cans lower power band. I had a 460/280 cam in a 302 with a 2000 rpm stall and loved it

2500 stall would be for a car with high horsepower but low torque at low rpm. It allows the engine to get into the power band before engaging the trans. They call them loose because there is a lot of "slippage" uses more gas and doesn't like to go from a slow start. May understanding is something less than 2000 would be decent for a mild engine.

I had that setup in a 1980 F150. It worked great never had slip or any other problems. I am thinking of doing the same thing on my 68 but I am not sure yet.

Thanks for the responses, I called tci and b&m and they both recommended a converter in the 2000-2500 range with the setup I have. I hope it lowers my times at the strip a fair ammount. It's an absolute dog off the line

In defense of my response, you did say "streetable" not quicker at the track. I still agree with Mlarv5's first response that it needs to match the engines power band AND your intentions for track use.

I plan on taking it to the strip once or twice a year so performance isn't my #1 priority. It wakes up at 3k buy I'm thinking that's a ltop high if a converter for a daily driven car

I ordered the b&m trans pak and their 2400 converter. I got into the trans today and the ammount of clutch material that's laying in every crevice is kinda concerning me. I hope there's nothing too bad when I get into the planets

So I got everything back together and in the car. It shifted great and the new converter made a world of difference. After about 15 miles of babying the thing it started dragging so I parked it, let it cool and flushed the fluid thinking it was just a normal break in procedure, I readjusted bands at this point too. The next day it slipped intermittently in all the gears, and got progressively worse. I finally got fed up with it and pulled the bigger back out. I went through it surgically looking for signs of incorrect part installation. Everything seemed normal untill I got to the bands/clutches. The intermediate band was toast and the forward clutch had a little metal nub on it that destroyed the clutch pack. But that's not all. The reverse/high band delaminated sending melted clutch throughout the trans and destroying the drum in the process.

Damn that sucks. I know how you feel i rebuilt my transmission like 3 times till i threw in the towel gave it to a shop ran for a month till the output shaft popped out making the governor rub on the housing so after that its been fine (knock on wood). If you have trouble finding parts i got all my rebuild kits from macko transmission? I think that was the name but that had everything. And i had to have a transmission shop order me the governor for me. So don't give up! You'll get it! Haha

I think that's where I've been ordering my stuff to. I'm just frustrated because everything's pointing to manufacturing defects

Auto trannys are a PITA to rebuild and get right. I hate to say this but you would be better off bringing it to a good tranny shop and just have them do it. You will get a warranty and piece of mind it is done correct. Trust me I have tried several times to do these and lets just say mine is going to the shop to get done.

Make sure its a good known shop the one i took mine too wouldn't do **** for me after the never even adjusted the bands and when they put the wrong snap ring in they wouldn't repair my transmission said i was beating on it causing it to come apart

Damn you have to have the transmission spotless when you put it back together and make sure everything is torqued correctly. So are they saying the TC was bad and ****ed everything up?

It was surgically clean and I was terrified of messing something up so I made damn sure everything was torqued to spec. The think it was a pressure problem. My theory is that the little tit on the clutch are through the material and sent that through the front pump messing that up which then demolished the bands and drums.... I'm still waiting for a call back and I talked to a technical rep at 6:30 am their time.... In not very find of B&m at the moment
