Awesome job , and great how to video for the rear camber.
I need to do mine before next year's autox but don't know weather to use my gutted aspire beam (no torsion bar) and festive mounts or swap to the festive beam and run aspire spindle's.

This will never get old.
Good Job!

Nice work John!

The carb parts didn't come in til yesterday so I only got to take the white Festiva to the autocross. Jacob (my BIL that works at Michelin) had been ribbing his boss that a Festiva was going to outrun his pro-touring Chevelle, and we thought we'd need the red car to get the job done. We were dissapointed when the parts didn't show in time. I swapped the 13's with R888's back on the white one and took the roof rack and spare tire/jack out to shed extra weight but didn't do anything else to prep it.

We took turns driving and Jacob was catching on pretty quickly. It started puking oil from the valve cover breather after the third run; the base of it had split and it was leaking badly. We had to make an Oreilly's run to get parts to fix it, hose to remote-mount the new breather/filter, and brake cleaner/towels to wash off all the oil that had leaked everywhere. We missed seven morning runs but was able to get back in time to get lunch with the group and make all of the evening runs.

There were some pretty serious cars and drivers at the event. 1-6th place were all either Michelin drivers or were with the SCCA club that setup the event the day before with the same layout so they had more practice. The Evo was a fully built time attack race car that was trailered there, the Z06 was a streetable racecar with sponsor decals covering it, the Subarus were modified, the Mini was modified and on slicks... these guys weren't playing!

Jacob's boss ended up bringing his newer Camaro SS with Detroit Speed susupension parts, engine work, and sticky tires which I figured would be even quicker than the Chevelle. He placed 20th out of 45 entries with a 56.612. My best was a 54.114 which put me in 10th... very suprising for not getting all the runs in to learn the track, having completely blown front coilovers, and only around 75 hp. They're supposed to have two autocrosses next year so hopefully we can go back with the red car and maybe place even better!

Yeah I originally had 40 DCOE's but swapped to 45 DHLA's. I can't edit the title to update it though.

I see why i thought you ran webers lol, i also see that you have the dellorto info in your sig haha

[Thebrandonbeezy]

Ohh my bad i thought you ran webers, they're dellorto's?

[theastronaut]

Hey, if it ain't fast... at least it's pretty!

I am pretty happy with how it looks!

Can you not slot out the tracks for the pins?
Like so.

Also, have you considered lighter springs to bing in the advance quicker?
I doubt the advance is your problem though. Sounds more like a jetting/synchronization issue to me. Though the timing will be nice after the fuel side is sorted.
Can you post a video of it acting up?

Also, a in the states genuine Weber parts supplier,

They're who i purchased my 32/36 from

I thought about slotting it slightly longer but it wouldn't add much advance; the current slot length only adds 17*, and it would add it very high in the rpm range with the stock springs- around 5k rpm. Lighter springs would help bring it in sooner though. The sync in good, it idles very smoothly and revs good, just has a big lean spot under low speed load that the new emulsion tubes should fix. I ended up emailing the guy I bought the carbs from, he had them in stock and all four with expedited shipping was cheaper than buying a set on eBay. They should be here Thursday. If they were Webers then parts would be more available here. I think I have a vid of going through second gear I can upload.

I drove the car around the school parking lot for the first time last weekend... needs serious tuning to make it run smoothly. Right now it's slower than my white '89.

I went over the carbs- checked the float level, fuel level in the bowl, adjusted the accelerator pump linkage, and reset the butterflies in the barrel so both barrels close completely at the same time. It idles much better now but there is still a dead spot. After searching arouind a bit I found that I have the wrong emulsion tubes- the current one are meant to lean out the mixture as it transitions to the main jets which is exactly what seems to be happening. I ordered the correct tubes from Italy today with expidited shipping, hopefully they'll be here in time to get it running properly before the Michelin autocross.

I tried to take the distributor apart to modify it for more centrifugal advance but was unsuccessful. I thought maybe the b6d advance parts would fit in the b3 distributor but that didn't work either. The b3 distributor only advances 17 degrees compared to the b6d's 25 degrees so it'll be down on power until I get that straightened out. I also started plumbing the engine for an air/oil separator, and began wiring the AFR gauge. I'll spend a few nights this week going over everything on the suspension- dialing in the ride height and alignment, and double checking all bolts/fasteners before I get it out on the road. Still need to go to the dmv to register it, get the bumper/hood/grill installed, and hook up the e-brake too.


First pic of all three together.

Well it looks sexy.

Thanks, I just stared at it and took pics for about an hour after I mounted the wheels and dropped it off the jack stands lol. I'm really happy with how it's turning out!


Forgot to upload and post this one earlier.

[Smoker]

Thanks!





They're 13x6 +18 offset with 185/60-13 Toyo R888 track tires. It's a really tight fit with the 185's even with the fenders rolled and pulled.

Sick build. Love the carbs

Thanks!

I'm sure you mentioned it and I missed it, but what are the specs on your wheels and tires on this car?
