i'm thinking bout swaping out my 700r4 for a th350 i have and i will be installing 4.10's. i'm just looking to see if anyone is running this set up on the street and how they like it. i was also wondering if anyone running a th350 can post any pics of their shifts and consoles.

 

both of the TH trannies will react about the same since internal gearing is too close to make a difference. I love my set-up, very streetable and gets with the program.

Just know you'll have to run a taller tire minimun 27" but a 28" will serve you better for lowering hwy rpm, right now with my set-up 60mph is right at 3500rpm.

If your going to run a stock type convertor that will help you some since engine will not be in power band right away like a higher stall would allow..will help keep tires somewhat gripping, but even with a junk motor and low gears you can do a good smoke display on command.

 

cool. next winter i will be replacing my 305 with a 350 i have but i'm gonna put in a more aggresive cam so this drive train should do well then.

 

Your on the right track...investing for the future

 

just out of curiosity, how does ur car do on the street and highway with 50/50's and 90/10's.

 

A honest unbiased opinon is that at first when coming off a completely stock suspension, it took some getting used to. First thing i noticed when giving it half throttle from a dead stop the front end threw itself up, it does this under half and full throttle applications-really loose on the way up.

Also noted under extreme braking-such as used when finish line driving at the track, the nose dips down pretty good too. If you were to just do a standing start, whomp on it to get the front end to extend, then immediately hit the brakes, front end compression is alot slower due to internal valving of the front struts-they are meant to extend quickly but have a slower compression rate than factory for obvious weight transfer reasons and holding the chasis up so as not to unload the rear tires after the hit.

It took a hour or so driving around town to get a feel for the suspension conversion, but that will be the case with any major change on a car weather it be transmissions, gear swap, engines, etc... This combination is in no way unsafe imo. Your not going to be a autocross champ by anymeans, but it's not designed for that purpose. It was a great change that really benfitted my raciong program with betteer consistency and street driving is now a "normal" state since I'm used to it. Just be prepared when making a swap with all these components the car will react differently than what your used to...but it should, otherwise what's the point?

I'll argue either side of the coin when it comes to cars and set-ups cause I've been around all types of motorsports and seen/heard opions/experiences from both sides, but I will say this based on growing up around hot rods and nice street cars-how many street cars get into a slamon competition on the street? how often is a complete autocross style suspension really gonna serve any purpose on the street other than stance? Many engaugments will be a stnading or rolling start, and even when your playing by yourself, it's how quickly can you accelerate...see where I'm going with this? For the average joe having a suspension geared towards stright line performance will net a better investment overall. Just my opinion, but in all my years I've never personally seen guys seeing who can weave in and out of traffic the fastest-that's all hollywood BS it's all who's just flat out faster. And also from personal experience I can tell you I never lost a standing start race on the street to anything in a stoplight to stoplight situation-or length of road that was maybe 600-1000' long. I was only running 13.00's at the track and running guys that were in the mid 11's, but the fact I could hook and go on any surface and it would give me plenty of lead over the other guys who could'nt hook up initally that once they started cathcing up it was all over. I'm in no way condoning street racing, but fact of the matter it happens wheather we like it or not-started waay before any of us were ever born or even thought of and will continue long after we're gone. It does no good to have 800hp if you can't use it, and a car that can utilize the full potential of a 350hp motor will always win.

 

cool. i got to wondering bout ur suspension, after u posted. see what i'm wanting to do is build a decent street car for those run what u brong and stfu events at a couple tracks. so far it all seems to be legal and i would still b able to drive to the track and bac home.
