3811  Camaro Research Group Discussion / Restoration / Re: What's the correct paint procedure for the inside lower valance? on: June 07, 2006, 11:55:29 AM
None of the exterior color-painted front sheet metal panels (hood, fenders, header, valance, fender extensions) had color on the inside; they were hung on a front end "buck" conveyor carrier in approximate car position with several inches between panels, and the valance panel outer surface faced upwards. Any color on the inside surfaces was overspray from spraying the edges. The inside surfaces were semi-gloss black flow-coat primer.

John,

Did anyone ever take pictures of any of these processes?  I personally would love to see how this, and many other processes were done. 
In lieu of pictures, think you could make a sketch or two showing how this arrangement was laid-out for painting?

Steve

I don't have any photos of the Chevrolet sheet metal paint process, although I saw it in production many times (who knew it would be of interest 37 years later?); just visualize a complete car set of front sheet metal on a floor-mounted conveyor carrier, with the panels mounted in car position, with about a 5"-6" gap between the edges of the hood and fenders (to get color on the vertical surface of the fender reinforcement) and a 2"-3" gap between the other panels.

Thanks for the info John. So head bolts are head bolts---there are no "special" head bolts for the 302's?

Nope - there was nothing special about 302 head bolts - they used the same bolts as any other small-block.

The outer portion of the standard grille is always painted matching body color.

Head bolts typically have a "circle" headmark. Aluminum intake bolts are plain hex head (no flange or integral washer), typically with "A", "TR", or "M" headmarks; lock washers were not used.

Any hardware or auto parts store should have "Lock-Ease"; it comes in a dark blue plastic bottle.

One more thing to add, V was use for the V8's at Flint in 67 and up, but the L6 engines were still stamped with F for 67, 68 and part of 69.

That's why the change was made; the L-6 engines were made at the "Flint Motor Plant" in downtown Flint, and the Flint V-8 Engine Plant's "F" prefix was changed to "V" in 1967 to eliminate confusion in warranty reporting.

Thank you. Thanks exactly the information that I'm looking for. When I press out the pins I will measure the openings. Then
I will draw my conclusions as what to do for my restoration. How is the lubrication to the floating pins accomplished. Are they
under oil pressure or just simply splash lubrication.



Just splash lubrication - the only pressure lubrication in the crankcase is through the cam journals to the crank main and rod journals.
3819  Camaro Research Group Discussion / Restoration / Re: 1969 z/28 connecting rods on: May 29, 2006, 06:04:07 PM
Yes, as far as I know, the LT-1 rods had the "0" in the cap end of the forging. The small end I.D. of a pressed-pin rod is smaller than the I.D. of a floating-pin rod; the same piston pin diameter is used for all pistons (.9270"-.9273"), but that pin is a .0018"-.0016" interference fit in a pressed-pin rod, and is a .0001-.0008" clearance fit in the floating-pin rod. The pin hole is drilled larger in the floating-pin rod, that end of the rod is coated with copper babbitt bearing material, then it's finish-honed to the proper oversize to ensure .0001"-.0008" clearance to the pin to provide for lubrication.

The engine code shown on the P-O-P is the same as the one stamped on the engine's front pad (that's where the clerk got it who typed up the P-O-P plate), and the Flint prefix was "F" through 1966, and "V" starting in 1967. If the decoder you mention says Flint had an "F" prefix after 1966, it's wrong.

The natural color of freshly-ground solder is like yellowish aluminum, although the assembly plant hot phosphate treatment prior to prime in the paint shop may affect its color.
3822  Camaro Research Group Discussion / Originality / Re: 1969 Z28 302 on: May 29, 2006, 11:12:22 AM
What spec are you looking for? It had a forged crank, "pink" rods, forged 11:1 domed pistons with floating pins, 186 heads with 2.02/1.60 valves, heat-treated rocker arms, the "30-30" solid-lifter cam, a high-rise aluminum intake, and a 780CFM vacuum-secondary Holley 4053 carb.  Smiley

"V" is the correct prefix for a Flint-built engine (from '67-up; prior to '67 it was "F"); it would be "T" if it was a Tonawanda-built engine, and both engine plants supplied Camaro engines.
3824  Camaro Research Group Discussion / General Discussion / Re: Original panels? Sail panel seam paint crazing on: May 29, 2006, 10:59:15 AM
My all-original 69Z also shows some very light crazing and some show-through of tiny pits under the paint at the roof-to-quarter solder joint on the driver's side; this is quite common on original-paint cars. If you had seen the production process (open solder pots, applying it with hickory paddles and a torch, then grinding and pit-filling, all with the body moving at 70 per hour), you'd be amazed that solder joints lasted as long as they did in a joint that long.  Smiley

Did you bench-bleed the new master cylinder before installing it?
