TCI to start new R&D Project with a C10!

These trucks are really hard on parts in a autocross/road race environment.

Chris,

That's good to know.

Lots of learning on watching this one.

We've made a few more revisions but the project is coming along quickly.

There was some discussion about which c-notch design we were going to use. The round style won out almost unanimously.





Mocking up the anti-sway bar and a few other items. This crossmember is going to be one beefy dewd once it is all boxed in and fully welded.








Torque Arm mount, I believe this is revision #2

Great minds think alike I guess.

Now if I can just convince the powers that be that we also need a turbo LQ4 under the hood.

If you guys were closer, I'd take you for a ride. There wouldn't be much more convincing necessary

Lookin' good! Really diggin' the front set-up. Have you done any FEA on supporting the rear end with the coilovers behind the C-Notch? A while ago, I ran across a thread that discussed how C-Notching can weaken the frame's integrity. It made some pretty good points. If I run across it again, I'll share the link here. Keep up the good work!

If it's the discussion I'm thinking about, it's in the FAQ/Suspension stickys....

The decision makers have driven Skrape's Turbo LS3 Nova Wagon but they are still a bit old school........carbs and all

I hopped on Craigslist earlier today and found a LQ4/4L80 combo with less than 80K original miles for cheap so I forwarded the link over to them.

The C10 frame is definitely more stout than the pre 60's frames we've been c-notching for 30+ years. These guys are pretty smart though and in some cases we've had to add extra bracing if it wasn't up to snuff.

Glad to see you guys are doing your homework! If you haven't guessed by now, I'm in engineering for my day job, and run a part time speed shop on the side. Unfortunately, that means I'm hard to impress, but you guys are definitely putting the icing on the cake with this. Keep the documentation of the development coming, awesome stuff!

[slow4dr]

No worries, it's refreshing to hear good questions during this process. We are one of the few companies that doesn't mind posting pics of the "process".


Well, good news, The craigslist link I sent to Sal & Ed about the LQ4/4L80E actually worked. I go pick it up after lunch.

Haha that's awesome. What is the going rate for that combo out by you?

We picked this one up with 78K miles for $2500. Compared to the aluminum counterparts I have been seeing this was a steal and the 4L80 is icing on the cake.

Looks good guys. I was into street rods in the 80's and used your stuff helping a friend build a couple of model A's. Nice to see you working on this era truck.

Nice grab!

That's a bit higher than that combo goes for here, but it looks clean as a whistle, and complete. Awesome score. What's the plan with that? Boost!?

As much as I'd personally love to throw a turbo on it I highly doubt that it will happen. That's not to say I won't be making a few calls to some guys I know at Garrett & Turbonetics. Although, one of our very good local customers just happens to be one of KenneBell's top dealers and tuners. That temptation is always lingering over us too.

If the forced induction thing doesn't happen we'll probably just do cam only. I think The 317 heads will be a pretty good match for our intended usage.

I'm excited for this package!!!

Keep building

More parts mock up













Holley oil pan definitely isn't going to clear.



F-Body pan clears the rack but interferes with two bolts on the back of the crossmember. Engine needs to go back.

Have you looked at the Mast Motorsports Oil Pans?

http://www.mastmotorsports.com/view.php?id=160&c=49&s=7

Seems like I heard somewhere that they have a little more clearance than the F-Body pans. But it's always good to move the engine back like you mentioned for weight distribution.

What did you come up with on the spindles? You had mentioned a few posts back that you were developing your own since the CPP MOD spindle didn't work out....

Everything is looking great BTW.!!!!

[aggie91]

There is also the LSA oil pan. It has a different sump shape then the F body pan. It a little bit deeper then the F body pan, but not near as deep as the truck pan.

Price and availability always has us using the F-Body pan for mock up. The engine only needed to go back roughly 1/8" to clear the sump.

We took a mod spindle, cut off the steering arm, machined two faces on the spindle and bolted on one of our steering arms. This will atleast get us where we need to be dimensionally for mock up.

Watching this progress gives a lot of insight into what our top notch vendors go through to make quality products available for us truck guys.

[slow4dr]

Here are the plates that will be used to make the upper control arm fixtures.



Rear shock mount fixtures



Panhard bar installed

Double checking the geometry






Things to note: Driver side spindle is different than Passenger. The passenger side design is our new custom set-up. It is based on a C10 pin and uses the factory lower ball joint with a heavy duty Moog upper. The steering arm is removable and helped us attain the geometry and turning radius we desired.















How's this for ground clearance? We tried and accomplished keeping all suspension parts on the same plane as the bottom of the frame.
