Decoding/Numbers / 1969 Z28 10 10 X33D80
« on: September 30, 2023, 05:48:00 PM »
Since everyone's default is to assume it's fake, please evaluate this trim tag and provide me your thoughts.  Car is non-original engine, so no validation hope there.

Legit?  Looks good to me, what say the experts?

Maintenance / At a loss - engine stalls under load
« on: July 04, 2022, 05:57:29 PM »
Looking for some insight on troubleshooting my engine troubles.  Car starts, idles, drives out fine until you give it any heavy throttle.  I'm not talking mash to the floor, just hard acceleration, say 1/2 to 3/4 throttle.  When you do that, engine stumbles, then dies.  Quickly restarts and runs fine at light/partial throttle.  Car will rev in neutral without issue.  Car also seems to be able to handle heavier throttle when I first take it out.  After about 1 mile of running through the gears a few times, it can't handle heavy throttle.  I started to troubleshoot, then fell into the black hole of replacing parts one at a time to no avail.  Here's what I've done/checked:
1) checked plugs - fine
2) check resistance on plug wires - fine
3) checked coil - fine
4) replaced points with electronic module / along with coil
5) checked timing - fine
6) plugged vacuum advance - no change other than difficult idling
7) changed plug wires
8) changed fuel pump

What am I missing?  BTW, it's a solid lifter 427 built to stock specs - heads, cam, carb, distributor are all OE stuff.

Decoding/Numbers / 499 dizzy - what do you think about stamp?

Legit or restamp?

Originality / 69 Camaro Trunk Divider
« on: May 14, 2021, 09:03:41 AM »
I started a thread over @ SYC regarding restoring my original trunk divider.  Mine had obviously been hit with trunk spatter by the 4th owner of the car.   I wonder if this divider was in place when Fisher body applied the trunk spatter and could have some spatter on it when delivered to assembly.  Anyone have definitive info on this?


Restoration / Help needed - 69 COPO brakes and firewall
« on: November 22, 2020, 03:06:07 PM »
Working on getting the car back together and ran across a couple of things that confuse me.  Start with the disc brake piping...I have all dated components proportion valve, distribution block, 309 MC.  Bought a stainless line kit from HBC and am now thinking I either chose the wrong kit or they shipped me the wrong kit.  The fitting sizes and pre-form bends don't jive with what I have.  Before I call them on Monday, can someone confirm a few things based on what they have?  My MC has port threads for a blue fitting on the rear and a green fitting on the front.  My proportion valve has a green fitting on front and back, brass colored on the two front sides (both those matched the lines I rec'vd) , and a pinkish fitting on the rear side.  My prop valve has pinkish fitting size threads on both the front and side (poor sketch attached). Don't pay attention to the two lines in the MC, just there to prevent leaks.
Firewall - there is a hole in my new firewall pad centered over the tunnel.  There is a somewhat corresponding hole in my firewall - what goes in there?  There is also a small hole to the inside of my speedo cable clip.  What goes there - I don't recall removing anything from these spots when I disassembled the car.

Restoration / Seam sealer question....
« on: June 03, 2020, 02:05:19 AM »
Is there an application of seam sealer on the leading edge of the rocker panel (69 Camaro) designed to seal the flange gap from when the racker panel was formed?  This surface would be what mates to the back edge of the front fender.

Restoration / Correct Finishes?
« on: April 06, 2020, 12:51:25 AM »
Late Sept. 69 Camaro - looking for definitive answers on correct finishes for some smaller items.  I have the MacNeish book and have scoured the original cars/restoration sections to find answers.  Those threads answered most of my questions, but have a few that I'm unsure on:
Brake line clips - crossmember
Brake line clips - frame/underbody
Brake line frame stands - top of front subframe on each side
Brake hose clip on upper a-arm
Parking brake cable hook
Mounting bolts for the above?

Thanks in advance for your help....I'm sure I'll come across other items I'm unsure about!

How does his one look?

Decoding/Numbers / Late build COPO distributors
« on: August 14, 2019, 02:20:35 AM »
Did all 69 COPO Camaro use the 111499 distributor or did late builds get the 1112000 distributor?

Decoding/Numbers / Wiper motor tag decode
« on: August 05, 2019, 11:15:06 PM »
Can someone decode the numbers on this foil tag that is on the bottom of my wiper motor - 1969 Camaro.

Restoration / BE COPO rear questions
« on: June 11, 2019, 12:09:36 AM »
Working on cleaning up my BE rear and have a couple of questions.  Is this the correct pinion yoke for a COPO application?  I've read where the joints should be held by straps/bolts instead of u-bolts like this one?  Also noticed a "58" mark above the cast date tag.  Anyone know what that is for?  And, finally, Noticed a "D" stamped below and left of the BE stamp.....any idea what that is for?

Restoration / Correct Hurst Shift rods
« on: May 14, 2019, 12:52:22 AM »
Are the factory shifter linkage rods for a Hurst Competition Plus (with Muncie) the same between big block and small block applications?  I'm looking to source a set of originals and see that the repro guys list them as separate part numbers so am assuming they are different.  If different, is it because there is a different offset in the engine position between big and small block applications?

Restoration / X44 Wheel Openings
« on: March 23, 2019, 01:34:54 AM »
My 1969 X44 car had X11 trim (wheel opening moulding, quarter louvers, & drip rail chrome) added in the late 1970's.  The car is now under restoration and I intend to bring it back to the X44 configuration.  My question is related to the wheel openings and what holes if any were in the rear quarter openings, front fender openings, and lower fender pieces for the trim?  I'm assuming that on X44 cars, no trim holes existed, but want to be sure on this one.

Restoration / Acceptable date codes - 1969 427 COPO Camaro
« on: December 27, 2018, 10:24:30 AM »
Posted this over at SYC also.....Trying to track down a few items for my car (09D 1969 Camaro) and notice a lack of parts dated July-Sept. of 69. I've read that the 499 dizzy was last produced with an April date....what about things like 163 intakes, 837 alternators, 291 heads, exhaust manifolds, starters, etc. Was there a gap in production at some of these manufacturers due to the 1969 design carryover into mid-November? Any insight appreciated!
