nice wildcat

I love the Wild Cat.  And enjoyed the video.  As I recall most of those pre-emissions cars use a 0.35 plug gap.
Almost like a Starfire. Very cool car.

That have the variable-stall th400 still?

@Junkyard Digs Awesome. For grins&giggles, you can mount a push button on the dash for the stator solenoid. The electric switch on the carb will be the stator switch, the one on the pedal will be kickdown. If you ever swap it out, it would be handy for an off-road/rock crawler rig.

Sure does!

I'd like to know too.  Was that and intake poking through the hood or an exhaust???

Back in the early 70s my dad had a 67 Buick Wildcat 401 4 barrel 4 door ... for his work car, that thing would haul ass!
Racer 67 (4 months ago)
I would of ditch'd the points and put a pertronix ignitor in it! I put one in my 67 impalas distributor and it works great way better than points!

Nice Wildcat, I have a 64 Interceptor Wildcat they’re such huge cars but they’re really fast too😎👍

Why do you want to hook up the timing light as close to the #1 plug as you can? As electricity travels at the speed of light what difference will it make?

use colortune for carb idle mix

I have a tbi set up for a 454 91 dually. All stock...

Get rid of the points, take em back to the store, buy a Petronix upgrade kit. You'll have more time for Xbox and Beers.

Hi All , nice video. With first time tune on older cars that i buy i keep a small notepad / diary in the gloveboxI keep track of fuel usage and oil usage, any smoking at particular revs or speeds. When it gets it first tune, i first get a timing light and record the current timing setting at idle with the dizzy vacum hose attached, and also a second reading the the hose removed and the plugged * typically a tiny screwdriver or self tapping screw. Next i switch of and count the turn of the mixture screw until they bottom out and fully seat. As the engine is off, i take of the dizzy cap, inspect for hair line cracks inside the cap, and the hand turn the engine and get the points gap. Next i rock the engines crank but turning clockwise and anticlockwise to get a rough guide on timing chain stretch. That is about it on prep, i then remove all consumables, eg plugs, plug wires, dizzy cap, rotor points - and condenser ( you can change the points say 3 or 4 times, but then you need to change them both, the condenser does wear out or like a coil does not perform optimum ) Anything that looks good, goes in a plastic bag ( or those larger $2 junk shop lunch boxes ) and sits on the shelf I tend to keep the points system, as i dont drive the older cars much, say 2 to 3 tanks of fuel a year so it will take a while before they say 5,000 to 10,000 miles and require clean / adjust / replace RegardsGeorge

Love that Wildcat. Still love the '70-'74 Skylark.

If you have a TH400 in it, you have a SWITCH PITCH torque converter !! wire it to a line lock momentary switch and ENJOY 2200 STALL !!
Junkyard Digs (1 year ago)
+Bill C way ahead of you!! 2200 low and 2800 high stall

Now I just need something with a carburetor to apply the knowledge. Too bad I cannot tune a lawnmower like a car.
Peter Kapica (1 year ago)
Junkyard Digs with usually 1 mix screw. When I had an atv, it had I think 2 mix screws and idle was determined by throttle cable tension
Junkyard Digs (1 year ago)
+The Decimator ah but you can!😃

Set the dwell to exactly 30 degrees
Giđεφn (1 year ago)
The use of a tach dwell meter , timing light mean a world of a difference in throttle response!
BatGoat (1 year ago)
After hearing deployment and drill I'm wondering if you are in the N.G. or R.R.?   Great show! I love the Wildcat, it reminds me of my buddies Starfire.  We used to tool around Grand Forks, N.D. in that thing
BatGoat (9 months ago)
Awesome, thank you for serving.  I was a Navy Corpsman years ago.
Junkyard Digs (1 year ago)
+Mike Stone NG! And yeah its the ulitmate cruiser!
Shane R (1 year ago)
yeah business cards are side of the road shit, your dwell must be waaaaaaay off
Shane R (1 year ago)
you took the distributor cap off... and didn't replace the points!!!!!!!!! you do know that dwell is important, and has a short life span as far as staying set
Shane R (1 year ago)
Junkyard Digs ???????? so you trust some idiots adjustments... psh
Junkyard Digs (1 year ago)
+Shane Rossbo everything had already been replaced by the previous owner
Shane R (1 year ago)
tune? but that cars waaaaay slow out of tune. maybe it needs more "timing" seriously, advance that shit

Except for chase cars, a script, fake laughs and an unlimited budget, you are right

Junkyard Digs nice 😁👍🏻

When I was growing up my dad had a 69 green on green Wildcat I don't remember the size of the engine he told me twice what the engine was size-wise but as of right now all of the member should have a 4-barrel carburetor. It was a two-door all power windows door locks Ext. That thing was a beast and it got up and moved it hauled ass. He made a couple of comments when I showed him some pictures in the radio that he wish he still had that cold today Orna Dental car that he had that I posted and sit in this comment and he still had today. I wish he still did. I will love if I had the money to buy a a car like that and just give it to him and then I would. But I would have it in writing or him his will that if something ever happened to my dad that 69 Wildcat would come back to me I would have a documented sing it comes to me if I could ever do that but it's a dream for me to do that for my dad

I like your story but it's a good example of why not to use an voice to text program.

Probably a 430
oh damn its that guy (1 year ago)
Back in 1980 I was in Nova Scotia, my cousin n I had a Buick Wildcat forget the year but it had a 401 in it with bucket seats and a console shift, we never drove the car because it needed a motor mount and an exhaust. Would you believe we bought the car for 25.00? True story :)
Frank W (3 months ago)
@Junkyard Digs my dad had a 1964 Wildcat and think it had the 401 co engine in it, 400 turbo trans. He purchased it New and originally had 2 4 barrel carburetor on it but had it changed to 1 4 barrel carburetor by the dealer. I am certain but the original carburetor / carburetors on the car were Rochester quadrajet, not Carter. He had the Wildcat till 1975 I would say and gave it to his brother.
Allan Francis (1 year ago)
oh damn its that guy lmao 😂😂 now anything that runs is worth 800

Hey there fellow bluenoser, my uncle had a 1966 comet caliente with a 390 ho motor. Use to cat and mouse the cops regular.

okay im really enjoying your channel

The distributor vacuum advance hose connects to a port on the carburetor. The hose for the transmission modulator connects to a port on the intake manifold. Is that spark plug plugging off the PCV grommet? I'd seriously get that sorted out right away. If the crankcase can't ventilate as designed and the blow-by vapors are trying to vent to the atmosphere through the oil filler cap that's a bad situation.
george maragos (9 months ago)
Many years ago, pre mid 60's, the vapors went out of the rocket to a hollow "walking stick" and was tubes down to about sump level and it just vent out, it was emissions and to try and reburn the gasses and give them another chance to go out the exhaust. But but some engines are designed to be sealad others vented, typically get it wrong and you get oil leaks

Good luck on the power tour , but there won't be many like yours showing pretty rare old car .
Junkyard Digs (1 year ago)
only found 1 other!
aaa just send it!
Jonah Halbert (2 years ago)
Man I love that car. Id trade my car for a Wildcat or something like it in a heartbeat. Im just mind blown at how Thunderhead289 knows how to tune the carb and ignition system. I still have to learn to do that! my Mercury probably runs like crap, but the only thing Ive done is replace the plug wires. You probably recognize my car from Instagram. Well I make videos about it so check out my channel if you want.
Jonah Halbert (2 years ago)
Junkyard Digs I sure will. Ive actually been subscribed to him for about a year now.

I love the peppermint on the dash of the wildcat! Really adds some 'flavor' to the car.
discerningmind (1 month ago)
I thought it was toss a candy onto the dash for every pretty girl they saw.

Evan Applegate should we leave it😂
