|vinniekq2||I use a TKO 600 and its tough,has 2 optional O/drive ratios.over 20 mpg is do able if the engine uses a moderate cam.My wifes 70 Camaro got 28/gallon with 2.73 gears and a mild 350,no o/drive.it was an automatic.|

I realize this is an old post, since I'm already set up with my M21 what might a m22z set cost me with a set of 3:08's out back,it seems the most logical choice.

|1ownerT||What ever trans you go with make sure you have a properly baffled oil pan on the engine if it will see a road course. Nothing like a long sweeper at high rpms to expose the oil pump pick up and spin some bearings.|

Drive a TKO before you buy one. Im not kidding here; I have a lot of customers that don't like getting in and out of 2nd gear. Don't take anyones word for it...try it yourself.
I would put a Richmond 2.88 1st gear ratio T10 in. Or if you plan on making power...an Auto Gear Muncie-based M22z (2.98 1st) 4spd.
I don't know much about the modern richmond T10s in terms of whats included but:
The Auto Gear unit is less than 2grand (not by much); and comes with an improved case, iron midplate, improved extension housing, italian gearset, roller sidecover and your choice of input and output splines.
Take the money you save with either trans and go through the rear end and clean it up. Heres some easy math:
4.11 rear x 2.20 1st Gear (preferred musclecar setup from the 60s) = 9.042 total reduction.
2.88 Richmond 1st x 3.08 rear = 8.87 total reduction.
Auto Gear specific 2.98 1st x 3.08 rear =9.178 total reduction
What this means: Car designers tried to match rear axles with 1st gears to get around a 9:1 total reduction (4.11 x 2.20, 3.73 x 2.50 etc) So if you can match your rear to a 1st gear and keep it around 9:1, you'll be happier.
Now, with a 4spd, your doing a lot less fab work, its lighter, shifts faster and keeping a 3.08 in the back with a 2.80+ 1st will get you better mileage than 3.73s and an OD.
Keep in mind ODs run hotter and louder and the more overdrive, the weaker it gets.
I sell TKO parts...don't break it because parts are hard to find and only come factory direct from Mexico. If you decide to go TKO, and need help identifying what youre looking at...just ask. Same with T56s or TR6060 (T56 Magnum)

|dumbmechanic||NV3500? I cannot say if it's better or worse than a t5, but it's what I have behind my 400hp sbc in a 5000lb truck. It has been holding up for 3 years now with me abusing it, and it was on the truck since 99 with no rebuild. I get 12-14 MPG depending on the temperature and tune...|

|F-BIRD'88||Both vehicles are too big too heavy with too much frontal area for mileage.|

I do want a overdrive tranny so should I just sell the t-5 set up? I'll keep my eye out for a cheaper 5 speed like a richmond or a tremec on ebay or craigslist.
I know but its better than my 13 second c10 which gets 7 miles a gallon. If i can get 18 with 3.55's in the rear and overdrive i'll be happy!

A Richmond street 5 speed is $2K.
A Richmond Super T-10 "wide ratio" w 3.42:1 first is $1.5K
Both have a steep 1st gear allowing modest gears for cruising. (3.08ish)
Use a tall street tire and switch to the shortest possible gummy tire (drag radial) for drag and gymkana.
thats your best compromise. Build the motor with a broad power band. it will work well.
A mild supercharged 350 gives the power, allows more modest gearing as well.
You have to realize as soon as you "cam up" a 5.3 L LS motor (for more power) the fuel mileage and broad power band is going to suffer.

|Dylanic_350||F-bird88, There is no engine or tranny in the camaro. It was a 250 straight six and a 3 speed saginaw when i first got it. The trans-am is a 350 with a world class t-5. I want a five speed but the tko-500 is expensive (2150.00) so I don't know another good choice|

|F-BIRD'88||What transmission is in the car now?|
|01-30-2011 12:19 PM|
Yes I am going to go with the MSD set up and through a carb on it for awhile but keep all the efi stuff for a later date until I can afford the fuel system.
As with the transmission is it an easy fit to the gen III or gen IV with its flywheel? (I know it might be a stupid question but I'm an automatic guy)

|Crosley||A 5.3 LS motor is not easy to adapt a distributor to.. a Friend of mine that dabbles with LS engines tells me the MSD LS-1 controller works great for the ignition with OE sensors and coils. A carb and intake bolted to the LS engine.|

I don't want to part with this car because it was my first car in 7th grade and I just recently got it back from the owner. The t-5 is still in the trans am and comes with everything so i'm "golden" there . I'm going to throw a carb on the 5.3 so i can just run a electric pump and keep things simple. Right now its got 3.08 peg leg rear gears that i'll keep till I can afford 3.55's or something...
I do appreciate all of your input though and I do understand it won't be the most effecient rig in town but it'll special to me. I know the t-5 isn't the best choice but its what i have at the moment
