OVERDRIVE in 2nd gen camaro
 
Hi guys I have a 1975 Camaro thats my new project car. I plan on keeping it a manual and putting either a 400 horse+ small block in or a gen IV 5.3 in it. I will keep the 10 bolt and add posi with 3.73's probably.

I plan to drive the car everywhere and blast down the strip without blowing it up.

My question is will a t-5 or t-56 last behind these engines or should I go with a tremec tko-500? I don't want to spend anything over 1200 bucks on a transmission for this car. I would like an overdrive tranny. Is there any other companies that make a t-5 or t-56?

What will all have to be changed in order to run one of these tranny's i.e hydraulic clutch, mounting, etc

T-5 won't last long. Anything but that. :D

I had a feeling I was going to hear that :). What would be another good option that wouldn't hurt my college wallet? lol

I have decided that I want to run a 5.3 out of a newer pickup and swap in a bigger cam for maybe 400 horse. Since I have my hands on a t-5 for free can I bolt the tranny right up to the new blocks without any other work?

I know i'm asking alot of questions but i'm really motivated to get this camaro on the road course this summer and yet be able to knock down 20 mpg on the way home :)

I'll let someone else with more knowledge than me answer that question. All I know is the T-5 is weak for high HP applications.
I do know, unless the T-5 comes with a pilot bushing, fly wheel, clutch disc, clutch plate, bell housing, linkage, shifter, cross member, and drive shaft, your going to need a fatter wallet than you think. You could get close to 20 MPG with a 300 HP, 4 SP, and 3:08's in the rear and still have fun on a road course for a lot less money. The LT-1 Z-28 came with 330 hp and was an awesome running car and that's what I would shoot for to run on reg gas. :D

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

Sounds like it. Don't forget your going to need a dist. also to replace the comp. controlled ignition. Goog luck with your project. :D

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.

Dylanic_350 01-30-2011 01:19 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)

Dylanic_350 01-30-2011 07:37 PM

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

Dylanic_350 01-30-2011 09:49 PM

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!

dumbmechanic 01-31-2011 12:27 PM

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... :D

What rigs are too heavy??? if a 06 crew cab with the 5.3 can get 20 mpgs and weighs 6,000 why can't my camaro get at least 18 with a 5.3 and a 5 speed?? I know you have like a million posts but it doesn't make sense if thats what your talking about

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)

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.

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.
