currently running ACDelco R44s and no issues,,,
hard to find these anymore so what does the F on R44F mean and are they compatible for a 69, back to stock, 302.
Thanks in advance.

Maintenance / Re: At a loss - engine stalls under load
« on: July 19, 2022, 05:07:44 PM »
Just throwing this out there.
After the floats checked, try increasing the squirter size +2 and test for any difference in stumble,
if it's better, then try the next accelerator cam up, try again and if the stumble is lessening, try the next couple of cams.
Had this stumbling and sometimes stalling issue with my stock 302 and when bumping up the accelerator cam, it took care of the stumble and stalling, therefore it was starving for fuel during load and acceleration by the pump cam curve not being enough.
It may be a good idea read and understand how these cams can affect your performance, for better or for worse.
Been thru it and I know your frustrations. Sometimes it just the simple checks we overlook.
Good Luck

Great replies and pictures. not sure when I will get to this, but when I do, I'll be sure to post the updated steps I uses to accomplish this.
I am still deciding on which headers to use, I would prefer to use the 1968 Z28 headers as first posted. 

Hey Jimmy and Buddy, could I ask you to post some pictures of the driverside and linkages,

does anyone have pictures of the 68 headers installed on a 69. looking for driver side to see if a linkage rod can be made to work.

nice, but can you still leave the reverse lock out linkage functional.

let's try this heading.
Anybody able to have 68 style factory headers on a 69 Z with the reverse lock out modified to work and also with power steering
Thanks in advance

General Discussion / 1968 Factory Headers
« on: June 07, 2022, 05:00:28 PM »
has anyone installed the 68 factory headers on a 69 z with power steering and most importantly keeping the reverse lock out linkage operational.
and if so, could I get some insight on how to before I purchase a pair.
Thank in Advance,

Which Holley Vacuum secondary spring are you running for the 1969 z28 Holley 780 4053 with the standard duntov speced cam.
Looking to have the secondaries fully opened sooner than 5600 rpms under load
thanks in advance

General Discussion / Re: Rear Fiber optic help
« on: April 26, 2022, 03:01:05 PM »
how long are the fiber optic cables, that may be of help in finding out where this was.
the receptor fittings and insert gromets don't appear to be 1969 issue, I could be incorrect though.
The thru the wall grommets look correct, but why would they be there when camaros lights are inside the body, only the license plate would go thru the wall.
or possibly those gromets fit into the light assembly other than camaro, just a guess could be for a cady or impala, full size car.
camaro coupe cable lengths are about 60".
my guess is that those cables, with that head configuration, may be about 115"-120" which would mead full size vehicle.

traced back on things that were recently done on the motor.
I just reinstalled the oe rebuilt ps pump and the rebuilt oe water pump, so we decided to run, as a process of illimitation. one at a time I eliminated the alternator, ps pump, clutch with fan, then the clutch only, then I took the fan off the clutch, and all was good. time and patience worked for me.
