Hopefully your '69 was kept in one of those 'barns' for most of the intervening 44 yrs..  Smiley
Where was this 500 acre estate, what part of what state?

The silver of that time frame was very susceptible to uv, rain, etc.. and of course, the original lacquer is very thin.   Be aware that to get past the oxydized level of paint, you will be *very thin*, and are likely to see 'thru' it to the primer underneath....    (but when I see primer peering thru very thin original lacquer, I see 'character'...  Smiley

Maybe someone here will have a more modern suggestion, but you're probably not going to 'make it perfect'..
If you want to 'cut faster', you might try some 'rubbing' compound on the top surfaces, and I'd suggest using it by hand, so you can more easily stop before going too far...   I'd rather leave a little silver even with spots  than have no silver left at all...?   Follow the rubbing compound with polish and I'd also put a good coat of wax over it once you find the right spot to stop..

i always was under the impression that Chevy was doing 'temperature' experiments with all vega engines?? Smiley

uhoh..  Bullitt is gonna switch his allegiance from Camaros to Vegas?  Smiley

J/K...  actually I'd like to see a pix of a 'not your average' vega as well.. Smiley

Click:  The vinyl top you pulled off looked too good to be original, and there appeared to be 'repair spots' under it?  so what that top a replacement and not original in your opinion?  and that didn't appear to be a car that sat outside very much in it's life...  not too bad at all in my opinion...

Kerr:   Was the car you purchased sitting outside?   uncared for? in the north?  if so, I'd suspect it could be lots worse than the pix that Click showed.  Seeing bubbles/lumps at the top front would concern me more than ones near the back glass I think.

That roller AMX could be pretty nice with a '69 Z28 drivetrain. Smiley

1299  Camaro Research Group Discussion / Maintenance / Re: Oil Pan leaks... ugh.. on: December 06, 2013, 01:47:51 PM
You certainly want to make sure you buy the correct gasket with the front seal thickness that matches whatever oil pan you have.

Not everyone is aware that Chevrolet changed the front seal radius on the small-block pan in 1975. All production pans prior to 1975 had a 2-1/4" seal radius, and used the "thin" (0.22") front seal. In 1975, the production pan seal radius changed to 2-3/8", and they used the "thick" (0.41") front seal. At the same time, ALL Service replacement pans manufactured after 1975, regardless of their intended application, got the 2-3/8" front seal radius and require the "thick" front seal. Fel-Pro (and others) who make the molded one-piece pan gasket have two part numbers - one with the "thin" front seal, and one with the "thick" front seal. If you use the gasket with the "thin" front seal on a pan that requires the "thick" front seal, it'll leak oil like gangbusters, and you can't stop it. Measure the pan before buying the gasket so you get the right one, per the photo below - you can't take a used one back.

Another great source for front leaks are the cheapo chrome Taiwan timing covers with the front seal flange spot-welded on; the production covers had the flange roller-welded on for a perfect seal, but the Taiwan geniuses didn't know why, so they took the cheap route and spot-welded it. Result? Leaks.
No worries there John.. Smiley    I don't buy Japanese *anything* as long as there's a choice, and buying a 'modernized Felrpo' oil pan gasket is about as far away from genuine GM as I am willing to go!   and engines built after '72 are on my 'trade off' rather than rebuild list!  Smiley  The newest engine I've ever rebuilt is for a '72 Corvette 350..  other than that they all lie between '55 and '71 Chevy.. and only one big block in that mix.. Smiley   My oil pan is NOS (bought from Chevy for the early Corvette Hipo engines about 40 yrs ago, and in the box since, and the timing chain cover is also good GM.. Smiley      (And I agree with the skepticism you express over most 'aftermarket' items, from foreign countries especially).

Find yourself a distributor with a 4 lobe cam (like the old Mallory Rev Pol) that I have..    no point bounce below 10k..  Smiley
1301  Camaro Research Group Discussion / Restoration / Re: RGR At It Again on: December 05, 2013, 05:47:33 PM
Hey Gary    go for a ride with Jerry     https://www.youtube.com/watch?v=tAt8N-vH0gg      I believe he said he was shifting above 8 grand
Oh yeah!!  Smiley    Nice ride.. Unbelievable to get thru 1/4 mi trap that quick.. Smiley   I bet HIS adrenaline was running high too!  Smiley
He ain't bad power shifting that trans either..   I'd love to see a video of his tach during that run.. Smiley

(and probably a BIG reason that 302's blew.. missing POWER shift to 3rd..  Smiley

Going to that link, you find out about a '68 movie called 'Speed Lovers' with Fred Lorenzen.       the trailer is *interesting*.. Smiley
I recall Fred Lorenzen (although I believe he was a Ford man), but I missed that movie at the time..     Smiley

1304  Camaro Research Group Discussion / Originality / Re: 1100837 Alternator Stamping - Original? on: December 05, 2013, 09:51:08 AM
The engine deck is a flat surface, and the gang holder apparently worked well.  The alternator body is a significantly curved surface over the the length of the stamped characters, and I would not think the same kind of gang holder would work very well, but I have NO idea how it was done originally, or how the restampers do it..?

What let go on those 302's Gary ? I would think valve train issues at those high R's. Did they run hardened push rods/guides , studs and girdles back in the day ? Bottom end should have took the estimated 400hp--and those block castings are pretty legendary in strength. Many a 331 used to run at the track. Well heavy pistons also. Have heard it was the "yanking" them back on the down strokes. Intake. No down force from above to help balance the load.

well, I've not personally blown one.. Smiley nor did any of my friends back then..  those engines would rev forever (*almost*).. Smiley    I always assumed the blown ones were by people accustomed to hydraulic lifter engines, where the lifters served as a rev limiter (governor)..  Smiley    back in '71, I bought a '67 Z28 engine from Paul Vanderlay.  The engine bottom end was prepped by Hank the Crank (CSC DynaRev series lower end, forgedtru pistons, lunati cam,etc) which would rev beyond 10K..  it came from a '67 Z28 drag raced in stock class by Jack Cooley (HOF drag racer from Louisiana).   He came off the line at 10,200 rpm, shifted at 9800 running 11.6 on 7" slicks and open headers. that was at/below the nat record in his NHRA class at the time.   (that engine is how I learned to love the sound of a high revving small block.. just hearing it made adrenaline flow thru my body!
