nice ....was the smoke the tires rubbing or the oil burning off?

i need to do that with my adult kids that looks like a blast

I can correct my earlier statement... brake fluid was the culprit (and it 'should' be sealed now)


Buy a Miata, put them in it, they'll never get back out. I love my Corvettes, but if I was only doing autocross.... Miata or even better, Honda2000 - but they're a lot more money to get into (2k v 10k in comparable condition).


i was thinking my C5 vert
 
how is the sending unit sealed on that gas tank? ( i think thats it , the small circular plate with small #32 hex screws towards front of tank?) that sure looks suspect to me
 
I think you're right.... now to figure out how to seal it. Wonder if my wife's mirrors are still available or if they're still lost from the last time I borrowed them....

In other news, I bought another carrier with 3.42 gears in it. Figure if it's not enough, I can get the 3.27 gear carrier built with whatever I figure is better (3.73 or whatever) - the other benefit is I can fun steeper gears for track days but more highway friendly for normal use.

and the well known benefit of having a backup diff in case one decides to put pretty sparkles on the pavement.

haters gotta hate, it's what they do. My dad told me when I was growing up that "no matter how beautiful the woman, there's someone out there that hates the very air she breaths."

I can't imagine not using it - but there's some that it's just not their deal. The others, well, they just gotta hate. Ah well, I'm glad I'm not them.

now with that said, this car is twisting the rules a bit - so I have to expect some complaints.... I'm just curious, though, if I'm going to see a bunch of cars with this rear suspension in 2022 and beyond... to me, that's the highest form of compliment (even though they'd die before admitting I had a good idea).

I know the feeling. I didn't twist the rule book - I just threw it out. Somebody on the CF once asked me if it was a kit car. When I said "no, it is a real '56", I never heard from them again. My brother got thrown out of the Jag club when he put C6 suspension and an LS in his 1950 XK 150. BTW, the Jag has a late Camaro differential mated to C6 control arms and spindles.

timing is a funny thing - while this may not be allowed in USCA, SCCA has a new class especially for it that started this year.

about the only thing I might do different if I built another would be use the C6 rear as well.... I didn't think there was enough room but there actually is - I heard someone had done it, but my tape measure said no.... having the extra footspace would be nice....

that unclamped hose does seem to be in the epicenter of the stain, what kind of pressure is in the tank? or is it just sloshing? and are you sure its venting?
 
it wasn't tight, but I think the problem is just the pressure from the weight of the fuel

hopefully this fixed it

You lost me on the clutch bellcrank issue. Your parts look the same as my '69 (and similar to a C2 arm on the shelf), including the zerk that gets lubed from underneath.

my initial problem was a squeak when you pressed the clutch pedal. the problem was the rod from the pedal was scraping the top of the hole in the firewall.

The bell arm has 2 different length arms on it. The long arm side was attached to rod that goes to the pedal. The shorter arm is the one that should have been attached to it. Basically someone welded it together wrong. Odds are yours is too.... how do I know? I spent more than a few days maintaining our shop trucks growing up - all were manual. All had that zert on the top of the bell crank.

So I took a chance, I took it apart, turn the arm around (so the long part goes to the clutch fork).... and now the clutch works perfectly (and no squeaking).

I bet someone at GM never realized the that because you could easily weld that together either way and it would work.... the right way to do what I did would be to reweld those arms on the opposite side... but who has time for that? :3rd: this works, it just means there is no clip holding the ball in place on the frame side. Also, for many cars the zert fitting would get knocked off when you used the clutch.....
 
confession time, I never even thought that the fuel push rod needed to stay in place when I eliminated the fuel pump.....edited Had I even thought it through a little bit, I'd have realized that the rod still needs to be in there to limit oil flow
thankfully sbc/bbc is the same diameter. I am impressed I found it in my piles of treasure

heat plug, pull plug, insert rod, reassemble.

also adjusted the valves, set the tire pressure to 45 psi, then scaled it (I swapped springs) - and it was close enoughedited

tomorrow, or day after, video of the festivities.

hmmm - Please smarten me up!

Can you explain why the fuel push rod needs to be in place when you remove the (mechanical) fuel pump? That is the one on the engine - right? I am getting ready to remove and block off mine too - maybe not...

Is it an "oil-thing," or hiding something else in place internally? Glad you found it. I'd be still looking.

Thanks and,
Cheers - Jim

yeah, premature celebration. it doesn't. back to my original plan of running straight 30w (or ignoring it).
 
So another day of autocross... this time a 'high speed' track.... new issues to overcome. As I mentioned, the oil solution wasn't... so back to my plan of running 30w.

In other news, running rich fouls plugs... yeah, not news

Starting to dial in suspension stuff - need to change the front springs again to a shorter spring (don't worry folks, I have lots of uses for coil over springs - so backstock really isn't a big deal at all)... need to put a bit more altitude in the rear then figure out why I go from neutral to understeer - I think tire pressure and shock settings can help but I'm going to have to go back to my suspension geometry books to relearn.

High speed means I got nearly to 100 mph - that was a lot of fun. Best part is I met several people very local to me who gave me lots of great feedback...

My 'new' issue is I got warm waiting in line - that might be part of a high idle issue that I solved (and didn't get nearly as warm the next time - 3 sessions of 4 runs each), but it's still something I need to focus on because it only gets warmer from here.

I may also have to admit I'm a "Corvette guy" - it was internally humorous to me that the first Ax - everyone would see my Corvette and be sure to let me know of other Corvette guys around.... I never realized it was a club... but then today one of the people that was really helpful had a friend show up who is dialing in his C3.... and I could help him... hmmm

for those curious I was dead middle of the pack. Best time was 52s by a Tesla and last was 1:12.... I started at 1:08, and progressed to 1:00.5 (which, for some reason annoyed me)
 
isn't running rich, fouling plugs and getting warm interrelated?

i think a 12 second improvement from first lap to last lap would make me happy

I found it odd that it annoyed me for the very reason you stated. Though on my fastest lap, it had one running issue, so maybe that was it. I love the 427, its power, its sound and its pedigree - but it's issues really make me question why I didn't simply buy a crate LS3 or LS7... the motor mounts for the C5 are still on the cradle

In other news, the clutch works perfect. I wonder how many people have been fighting the squeaking issue and never realized that the clutch feels wrong....

In the grand scheme of the universe this clutch arm discussion isn't terribly important, so we'll just have to respectfully disagree. IMO the arms seem to be in the correct position for leverage/travel, and the holes in the arms are in the correct place for attaching the return and anti-rattle springs, and the bottom position zerk allows lubing while under the car greasing the suspension.

I'm halfway through construction of an aluminum replacement for the stock clutch bellcrank, but I've found that my spare bellcrank that I was going to use to configure my welding jig is an early C2 unit, which has a different angle between the two arms.
