Re: Yelcamino 2.0

Quick question Herb

What shift stick did you use on your T56? I just received my T56 and the Stick that came with it, the one that is listed for a 66/67 chevelle looks like it will be excessively long.

Thanks

Hey Troy, I didn't realize the last time I posted was back in JULY!

I'm sorry I can't help you with your question, I have a TKO600 at the moment. Future plans call for a T56.

Re: Yelcamino 2.0

Nothing new to report other than getting some seat time in the El. A couple of weeks ago I did a SCCA autocross and last weekend the LS Fest. Here are a couple of shots my wife got of me on course at the NCM...

Re: Yelcamino 2.0

Since last August I've been pretty busy with going to school full time, but in between classes I made time to replace the TKO600 with a T56 Magnum from Bowler.



Obviously I started with the removal of the TKO600.



Next I installed the LS7 flywheel and block protector. Since I wanted to check the bellhousing alignment and I couldn't get the dial indicator's base to sit securely on the flywheel bolts, I cut a 1/4” thick plate for it to attach to. Not only did the base sit flat and secure, it also made the center post stick further through the hole in the trans plate making it a little easier to attach the dial indicator.



Following that I installed the Quicktime bellhousing and the front plate from the T56. First I checked to make sure the bell was parallel to the block (it was)…



Then I checked concentricity and came up with a total runout of .007”.



Let me back up a bit. Prior to the Quicktime bellhousing, I had originally bought a stock aluminum bellhousing but ran into an issue with the starter not fitting. After doing a little research, it turns out this is common depending on which version of starter and bellhousing you use. At first I did a little grinding on the starter nose to make it fit.





Here you can see where the starter nose hit the aluminum bell (marked with copper color).



I could have ground on the bell to make room, but I acquired a $250 gift certificate to Bowler, so I exchanged the aluminum bell for the Quicktime thinking I wouldn’t have any fitment issues.



Turns out I had the same issue with the Quicktime, so out came the grinder!
In this pic, you see on the left before I clearanced the block protector and on the right after.

Re: Yelcamino 2.0

And here’s the bell before and after grinding…



With the bellhousing aligned, I installed the LS7 clutch assembly and reinstalled the bellhousing for the final time.



With that done, I installed the TO bearing, measured for the air gap, and adjusted it.



Before I put the T56 in, I installed the new Tilton clutch MC and mounting kit I got from Bowler. It’s model specific to the early A-bodies and it fit very good. Because I have a hydroboost, the MC needed to be mounted on its side so the fittings didn’t run into the hydroboost body. The mounting bracket from Bowler has mounting holes so the MC can be upright or on its side without ruining the geometry between it and the clutch pedal. On this version of the MC, there are two outlet ports to choose from, one on top and the other at the end of the MC body. I used the one at the end.





There’s also this little adapter the bolts to the clutch pedal so the linkage rod pushes into the MC at the correct angle. Overall, this is a nice kit and I’ll be sure to install one of these on the Chevelle when I get back to it.



The next big step was getting the T56 installed. Other than having to massage the passenger side of the trans tunnel and trimming two little casting tabs off the side of the trans body, it fit in my custom trans tunnel like a charm!





Because the T56 is longer than the TKO and the trans mount is further back, I had to relocate the crossmember, which also necessitated modifying the exhaust. To relocate the crossmember, I cut the original mounting tabs off the frame to make room for these new tabs I made.



In this final shot, you can see the new tabs on the frame and the modified exaust (the X needed to be moved back to the clear the crossmember in its new location).



I still have to connect the three trans sensors, build a small console, and get the interior finished. Once I get those things knocked out, I think I'll be ready for the 2017 season.

Re: Yelcamino 2.0

Great to see you still have the 66 and still massaging it, Herb. I've been out of the game for a number of years but I think I'm ready to jump back in with both feet. One of the El Caminos I'm looking at, is a white 66.
Thanks for all the inspiration, my friend.

Is that a 4" aluminum drive shaft?

Hey Clint! Yep, we still have the El Camino. Glad to hear you're getting back into it!

No, it's a 3" aluminum with 1350 u-joints on both ends. It's actually from my C10. Since the T56 is longer than the TKO, this leftover from the C10 project just happened to be the right length.

You lucked out on the length being correct. My 4" MW shaft was over 800 bucks.

I know what you mean, these driveshafts ain't cheap! BTW, I was out in the shop today and it's a 3.5", not sure what made me think it was a 3".
