Please no bickering and I really just need resonses from thos ewith expierence on this matter. I am currently installing a CC306 in my car with stage 2 ported and polished heads, full length headers, LT4 intake, 52 mm throttle body and MSD. Now my question is will a 2500 stall be streetable enuff for me to drive this car and enjoy it. The car is drove regulary and is raced at least 3 weekends a month during the summer. I want descent power down low but considering it gets around 500 miles a week put on it I don't want a huge stall. Some feedback here would be greatly appreciated. And yes I am going to do the PCMforless tuning when finished with it.

Thank You for any input.

 

WHen i toasted my tranny, I was faced at which stall to get. I have a hot cam p&P'ed heads and all the goodies. I daily drive the car with about 65% freeway driving. SO when i talked to my guy he was like 2000 is a good bump, but not crazy like a 2800 stall. Even if its lock-up at free way speeds you could heat up the tranny and burn clutches.

Bearing in mind a 20 degree drop in tranny fluid doubles tranny life.

I got a high-perf rebuild a 2000 Percision Ind Vigi stall and im happy with it, I consider a 2400 stall considering the useage of the car.

With your cam, 2400-2600 would be nice. IF you did ALOT of track useage, minimal street, with PCMforless programing you could go whatever you want. 3200 or somthing like that. But your gonna have to figure out what the car is for and what it seems it is for mostly daily driving.

 

It is definetly a street car no doubt about that, we just play at the track quite often. So if the 2000 up stall will work that is what I want, not a 2800 or higher for a daily driver.

 

Nobody else here running CC306 with a A4???????

 

No CC306 but I run a Yank SY3500 converter in mine, ran a 12.411@109.00 w\ bolt-ons only and BFG drag radials. I used to drive the car every day and it was fine. You learn how to drive the higher stalls. You will kick yourself if you don`t get at least a 2800 w\ that large a cam. I would not go over 2800 since you have OBD1, the OBD1 computer will not run right w\ stalls over 2800. I have OBD2 and the computer seems much more agreable to the higher stall. I knocked 6 tenths of my time w\ the converter alone, no other mods between trips to the track and similar conditions.

 

I honestly don't think a 2500 stall is nearly enough for a high-rpm cam such as the CC306. It will take your car forever to reach its newer/higher powerband with that small of a stall. If you don't want to run anything over that sized stall, then I'd recommend going with a smaller cam that would take more advantage of your converter/set-up. But for mostly track-use, a Vig 3200 w/3.73 gears would work well in combination with the CC306, although not in your car because of the OBD1 PCM as already mentioned.

a minimum of 2800 stall and 3.73 gears. i'd say to go with a 3200 though. that LT4 intake won't match up to LT1 heads. unless some major work has been done. just get a stall with lockup and you won't have any problems on the highway. don't forget to add a tranny cooler also.

 

go higher than that, at least a 2800....i am installing a TCI 3000 in my OBD1, and IF it does have the "high stall" problem, send it to PCMforless, u shouldn't need to send it otherwise......a guy I know who knows his **** about converters, said 3000 may or may not give the high stall prob, but i am going to have a 2.5 STR, so we will just see...

In my opinion....AT LEAST 2800!!!!!! it will still be very streetable, and, u will hate yourself if u go less!

 

I have a 306 cam in my 92 Vette, and I had a 2800 with 3.73's to begin with(with a best 60' of 1.67), and my car was bogging off of the line. I had the stall upgraded to a 3600 and now my car hooks hard, and now my best 60' is 1.57. I drive my car everyday, unless it is raining out. I am running a speed density setup, and I haven't had the first problem with mine as everyone else is always talking of........ My best Et is 11.50 @119.66 with no head work other than matching the head intake runners to the intake!!!!!!

 

Well I guess that my question was misunderstood. I am aware of what it needs to perform the best at the track, I'm looking for the best streetable set up I guess. I know some guys are running the cc305 cam with no probs so I was in hopes that a 25 would be fine for mine.

 

Dude streetability is not that much of an issue i am running the CC306 in a 383 will be going with a 3200 stall converter. the higher stall is only noticable when you have your foot in it. if you baby it you wont even know its there. And the CC306 needs at least a 3000 to get you into its powerband. Do the right thing the first time. Pro-Edge Converters $490.00 12 months street/strip warranty. not too bad

 

mine runs fine(see sig)though a 2600vig was ordered for my car,it was originaly intended for a (relatively)stock car but I keep adding parts!!!!!,I wonder where it really stalls w/ the 306cam??,make sure you bump up the tc lockup(cam surge is hell)to about 55mph!

 

PUT IN A 6-SPEED!!!!!!!! Really though, go with the 2800 minimum or just go smaller with the cam! Hell the convertor is a lock up unit anyway,1:1 ratio on the highway!!!~~~~rob
