I noticed an improvement driving with the 1.00" Moroso carburetor spacer plate installed and the Holley Float bowls stay cooler.

 

[Maniacmechanic1]

I went for a 10 mile ride on the highway.
Ok.
Came back & did a burnout.
Went around and parked the Grand Prix.
Revved it once and shut the engine off.
Opened the hood to check the Olds 425 engine.
Seen smoke !
The Wix Napa Gold Air filter was on Fire Smoldering.
Got the air cleaner off and tossed it 20 feet away.
Caught on fire in a burst of flames midair.

Sheet.

So now there is a 1970 Pontiac 455 stock air filter element.
Air cleaners are not supposed to burn....act as a flame arrester. The Napa Wix failed that.

Been fighting a lean pop sometimes.
Think the stock fuel sock came off the sending unit. See the Fuel pressure gauge dance around at random sometimes inside the car where I have it mounted.
I last had it out in 1998. Its original 1963. I ordered a new reproduction sending unit last night.
Going to mount the Mallory Comp 140 fuel pump back by the gas tank too.

What caused the A/F to catch on fire? Did the engine backfire?

 

[Maniacmechanic1]

Its my Opinion , K&N Air filters are best.
Never had one catch on fire in the Trans Am ! K&N I still have for it.

Fuel pump sucked in an air pocket I think.
Was not watching the fuel pressure gauge then.

Free's up both my legs for bracing!

Yes.
No seat belts.
It was a rare option in 1963.
Found a few sets OEM in past.
Made by American Parachute company.
They also supplied for the Corvette early years.
No one rides in the 63 Gp but me and a few crazy buds.
Don't take the wife or kids.

Ok if I die.

Found an Edelbrock Performer Intake I want used .,$75.
Offy Dual Port Intake works Ok but costing some Hp.
All I had 3 years back to get it going and fit the 4150 Holley.
Amazed how clean it is inside the intake yet.
Around 15 k miles driven so far with the 425 Olds V8.

I had an air cleaner catch fire once on me. It was one of those Edelbrock triangular foam ProFlo units.
When I shut the engine off, it briefly dieseled (ran backwards - hot summer day) and a carb does not care which direction the air goes through it -
it still adds fuel to the airflow through it. So fuel sprayed up and onto the foam element - and then caught on fire.
I will NEVER use one of those units again!

Brian, a phenolic spacer should run even cooler than the aluminum one.

It's Plastic Mike.
Some kind of Black Bakelight plastic.

It will still run cooler Brian.

I had a 2" installed on motor and it made a huge difference in carb temp.
It helped straighten the a/f mix also. (Supposedly)

My New sending unit got shipped out yesterday.
Going to try & wing the Edelbrock Performer Olds 455 Intake, fits 425 & Olds 400 also, all Tall deck models.

They passed a Gas Tax yesterday here in Illinois. Doubles July 1st.
So 87 Octane gas here will be well over $3.00 per gallon.
Everything has to run on 87 octane I own except the TA.
Cant afford 93 octane for 200 miles commute daily. It will likely be $4.25-$4.50 per gallon.
Runs on 87 octane the 63 Gp just High Heat does evil stuff. E10 alcohol boils in the Holley float bowls no no time flat.
A Rochestor Quadrajet does a better job with E10 87 gas. Have one off a 403 Olds V8, have to go through it., Eddie Olds 455 intake also set up for Quadrajet.

Welcome to my world. Connecticut has one of, if not the highest, gas tax in the nation! I feel for you Brian.

The Early Pontiac Widetrack cars had 0-30 OHM gas tank sending units.
Think It was same for Chevy and rest of GM.
