Starting a build on my old C3. 1974 with 350 and M21 4 speed. Have acquired a 2002 5.3 and a 2010 TR6060 six speed. I plan to do 95% of the work myself and will update nearly everything on the car.
The 5.3 is in good shape and needs little work for now. It was $500.00 with ECM and harness. I am stated on the harness mods.

The TR6060 was super low miles, came with all sensors, slave, ect. but had a broken main-shaft. This was a common problem (bad batch of shafts) they just replaced under warranty.

The good news is, I picked it up for $200.00 and it came with a new main-shaft!
With a little help from this forum the trans is back together. THANKS to the_merv for his gear puller mod.

While I am on the trans, it didn't come with a shifter and the stock external remote mounted shifter is a problem. It is too far back and the rear of it mounts to the floor pan. Some have used a shifter mounted over the detent plate, but this would be too far forward, and I don't want a funky truck shifter.

Even if I used the Ford version, it would be easier to modify, but still a lot of cutting and splicing.
SO--- I backyard engineered it.
I took a fleabay $20.00 shipped new take-off TKO 500/600 shifter and mounted it to give me the shifter location of a F body T56. Cut off what I didn't need. Took a rod end out of my spares box and cut out the ball and welded it to the shifter. Then a little angle and plate. Teflon washers and silicone grease on the shifter end. It shifts nicely (on the bench) thru all the gears.

Dude - thats f'n awesome.

So how much do you have in the trans?

Crazier

Your motor came with smooth valve covers? where are the mounting points for the coil packs?


and what is that nice (compared to how mine looks) cover on the intake?>

That is amazing. I am working on a Miata build that is using a CTS-V T-56 which also has the remote shifter and you just gave us a great representation of what we need to build for that shifter

I put an LQ9 6.0 and Richmond 6 speed in my 68 vette a few years back. You are really going to love driving it when you get done.

I am watching costs as I will be upgrading all systems, suspension, steering,A/C, ect. The trans was $200.00 with the new mainshaft included - I think he had that much in the shaft alone. Cr---- list and Flea Bay have been working for me.

2010 Camaro TR6060 six speed $200.00
Repair transmission Seals and bearings $65.50
New LS7 flywheel $85.00
Used (super low miles) take off LS7 clutch & pressure plate $175.00
New take off TKO 500/600 shifter $10.00
New pilot bearing $10.50
4 quarts Mobile 1 ATF $40.00
New flywheel and pressureplat bolts $14.00
Still need a clutch master and line + a trans mount - maybe another $150.00

The valve covers are stock. Just cut the coil mounting bosses off and brazed the holes up. I was going to polish them but got lazy and wrinkle painted them. I want to mount the coils on the firewall or somewhere out of the way to give a cleaner look.The Intake is stock as well. Just sand down and use high build primer. I will have to post a better picture.

Nice work on that shifter. May be worth reproducing in small quantities for the swap market. See if you can make a couple bucks for yourself.

I like your shifter idea. I've read threads on here about putting F-body and SSR tail housings on TR6060s but what you did was pretty clever. I was debating buying a Magnum for my 67 but I'd actually prefer the that the shifter be back further like a F-body t56. I've been checking ebay and cl for a TR6060 but haven't seen any yet, you definitely scored a heck of a deal on it.

BTLEGACY, I would like to follow that build. I have a 1960 Austin-Healy
Bugeye Sprite that is next on my swap list. I am thinking about a Ecotec or maybe even your drive-train. I picked up some GTO exhaust manifolds (new unused take offs - crate motor), for $50.00. I haven't found anyone using them on a C3, and don't know if they will work, if not I will save them for another time.

I used the 02 Z06 exhaust manifolds because they cleared the steering, z bar, and fit with the 02 batwing pan in my 68 vette.

Nice. Are you going to use the stock CV joint for the driveshaft?

74modified

Gary, I have seen people using the corvette manifolds, these GTO manifolds seem to point rearward - may be a problem.
westtexasbuff, I will probably use the stock tr6060 flanged output with a CV joint on the front of a one piece drive shaft. The fixed IRS differential of the C3 means I don't really need a slip yoke.

We will get a thread started shortly with some pics and current progress

F-body longtube headers will also work. Pacesetters in particular.

Q - That might be an option as well. Do your collectors hang down, or tuck up reasonably? I am also making this hard on myself as I am swapping in a Jeep Grand Cherokee power steering box, and it is a little larger than the stock power box.

-Q-

iTrader: (10)

They tuck way up tight...almost too tight. They are within 1/4 of the floorboard. I actually removed the heatshielding from the floorboard on the passenger side for extra room, but I think you could keep it there.

And that pic I posted on the driver's side looking down at the steering box is a little deceiving...there's more room than that. The pic is taken at an angle.

Q, good pics, looks like those fit well. I will keep them in mind. Working on routing parts of the wiring harness.
