Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!

Wont be a daily driver but as often as possible. Definately weekends and only a handful of track days. Once a month possibly during race season? As of right now only rod bolts but researching going forged bottom end.
If you do some bottom end tweeking then I'm right with Sean and everyone else. The 3.50 gear will be a load of fun. Rpms and durability was my only concern. I also agree with Sean on the 3.25 gears, they are noisy.

Definately more about power and fun then mileage. Was just trying to find a middle. Im down for the 3.50s. Ive built this car over and over to beat on and have fun and it being broke, whether its motor or trans, is proof im not nice to it. I want to be able to blow the tires off it at will or be able to go sideways when i want
May I ask how far into the motor you plan on going. And will your budget allow a good turbo. I have nothing against the 3.50 gear. Its just more of a track gear in my eyes.

so explain to me how a 3.50 gear ratio is not a very streetable gear on a turbo car then? bc i fail to see you show any proof of this when im giving you my proof of how it is, and with it being in a car with a trans with one less gear then mikes
Well here is his request.
1. Streetable
2. Durable
3. Cost is a factor.
So if he gos with a 3.50 gear there is a large chance that he will spin the engine rpms higher than the rods and pistons will like. Higher the gear the higher the max hp vs. Rpm generally is.
Now that can be adjusted with turbo size. But with that gear he may loose his durability due to rpm.
He could fix this with a custom turbo yes. My question here is how streetable dose the car need to be. Daily driver/ is this a car that will see a lot of track time. Or just a weekend driver.
And the bigger question of all,what all is he going to do to the motor?
Most everyone chooses a 3.08 or a 3.23 gear even with larger turbin turbos. A lot of track car choose 3.50 gears so they are farther out of the hole before boost sets in. Thus top end car.
That's all I'm getting at. The 60e trans also has a better over drive gear than a 80e. You will see lower final drive rpms out of a 60e than a 80e.
Hope you see what my consern is now. Like I said not trying to be cross with anyone.

Also I want to say I'm not trying to be cross. I completely understand there much newer technology since I was into the turbos last. And I'm man enough to state I don't know everything. but this isn't my first go around either with a motor and a turbo LOL.

the biggest issue mike will have is your going to have to give and take bc you cannot get the best of both worlds.. if you want mileage go with a 3.00 but its also going to slow the car down quite a bit.. i can cruise the highway with my 3.50's and a th400 with one less gear then him and yeah it may be about 33-3500 rpms.. but i can stick knock down 15-16 mpg's.. with a 4 speed and much lower rpms he could easily get 18-20.. and if someone wants to ***** about that in a turbo car... then you should not have the car in the first place... end of story.. because we didnt buy these for mileage.. everyone knows that
What rpm are you hitting peak up Sean. This is my main concern. unless he also has a unlimited budget to replace rods and pistons.
I understand you running smaller turbos.
Nope a 4l60e. 2700rpm is high rpm for a 4 speed v8 car. my raised mine for milage. most v8's carry enough torqe to cruise highway speeds and maintain around 2000rpm.
Not saying 3.50 is a bad gear. But there are more streetable gears.

not disagreeing with the fact that there is more streetable. if your only going for fuel mileage.. but lets be honest.. we didnt buy these cars to get great mileage. i run a 3.50 in mine and it is extremely streetable and i have a 3 spd instead of a 4. which means mike will be every bit just fine with the same gear. sure you could go with a 3.00 to get better mileage but then its not going to help when you go to the track or wanna have some fun. its just like how guys run a 3.73 when they have a 10 bolt in the car with a 4l60. it works just fine.. just like a 3.50 works great.
btw mike.. stay away from the 3.25 gear sets if you think about not going the 3.50 route.. i had three of them and bc they are not a very common gear set they are generally very loud..
and i would also bet that you had a 3 spd trans not a 4 like he has..
mike 3.50's will be great for your car. i have them in mine and am running a th400 and its very streetable and cruises down the highway great

If it helps I was running a 3.08 for the street and would switch 3rds to a 3.50 for the track. For street or highway I feel a 3.50 is alittle high myself. But for splitting often street/track. Iv seen a lot of people run 3.50 with plenty of luck.

Got a great deal on a moser 9". I dont think my stock 10 bolt w 3.73s is up to the task
25-2700 rpms still seem high with 3.50s. I guess if you guys think 3.50s will be better stoplight to stoplight, im good. If it will help build the boost and still be hghwy friendly im all for it
