General Discussion / Valve Covers: Shiny or Matte Finishes 69 z28

« on: July 17, 2020, 05:56:11 PM »

when did 69 z28s change from satin matte to shiny polished valve covers, or were they all polished.
does it have anything to do with drippers and no drippers, and if so when where they changed out.
Thanks in advance.

Carb issues, probably caused by gas. After running about a half tank of 93 Sunoco with Klutz additive, mixed at 16 oz for ten gallons, it has cleared up.
Thanks for everyone's input, it is greatly appreciated!

General Discussion / Sporadic chugging when cruising

« on: July 03, 2020, 07:22:57 PM »

Sporadically, my 302 chugs, almost feels like a misfire, when cruising on the highway.
Checked plugs and are burning clean.
It's been dyno tuned prior to reinstalling it back into car.
Running a Pertronix Flamethrower III.
Using 93 Sunoco with 1.5 oz per gallon of Klutz Octane Boost.

a buddy of mine has a z 302 with the same Pertronix and does the same thing.
Any thoughts
Thanks in Advance

location of numbers.
I have one with molded numbers on driver side of shroud and one one the pass side of the shroud.
I have also seen stamped numbers in the the flange that butts to radiator on pass side.
Am I splitting hairs.

finding 3 different sequences:
3938-615 
3938615  2
3938615
some are stamped and some are molded extrusions

which might be correct
Thanks in advance

General Discussion / Gas Smell 69 Z

« on: June 22, 2020, 02:22:48 PM »

Gas Fume smell inside cab when driving, just sometimes.
Smell out side sometimes, seems from rear area, after a drive.
Absolutely no drips or signs of leaks anywhere.
Removed air filter, nothing in there, 780 Holley carb and breather tubes are dry too.
Replaced gas cap.
any thoughts
Thanks in advance

sand blasted, then applied 2 coats of por15, 24 hours apart.... looks great!
now just waiting on my Gardner Exhaust, factory exact system.
looking forward to taking the droning, but sounds awesome, 2.5" Flowmasters American Thunder system and headers off.
Sacrifice some power and back to originality!
Nothing like the factory sound of a stock 302 through the deep tone transverse muffler without resonators!

Installing a pair of oer c.i. exhaust manifolds.
any suggestions on using por15 cast iron paint natural color
if untreated, they will probably rust over time.
what did or would you do...

Thanks in advance

it was the center force clutch causing these issues.
replaced with a LUK and very quiet and shifts like a hot knife thru butter.
