3691  Camaro Research Group Discussion / Restoration / Re: re-stamping a block on: April 19, 2006, 10:43:23 AM
As we understand it, the NCRS says this is OK and will not penalize the car.

Just to clarify - in NCRS Flight Judging, the key is whether any part "appears" as if it could be original, not whether it IS original (there's another separate judging category for untouched absolutely original cars where only originality is judged, with no consideration for Condition - that's "Star/Bowtie" judging).

Stamp pads are judged on their own merit, and with the library of over 8,000 macro photographs of Corvette engine pads to compare against, what's "typical", what's a known factory anomaly, and what's NOT "typical" are easily detected these days. A pad either appears to be typical of factory production or it doesn't; if it doesn't, it gets the appropriate deduction. Most of the points for the block are allocated to the casting number and casting date, not to the pad; the block is allocated 350 points (out of 4500 for the whole car), and only 88 of those points relate to the pad (25 for the engine plant stamp, 25 for the VIN derivative, and 38 for the pad surface).

My '69Z runs fine on 93 octane pump premium, with no detonation issues. I run 8* initial advance, with about 26* centrifugal, all in by 2800, and a NAPA/Echlin VC-1810 vacuum advance can that's fully-deployed at 8" Hg. and connected to full manifold vacuum. The late-closing intake valve and high overlap of the "30-30" cam brings the DCR down; a milder cam with an earlier-closing intake valve and less overlap will result in detonation with the stock 11:1 compression.

Four months is a bit of a stretch, although in NCRS judging we allow up to six months, recognizing that strange things happened occasionally. I'm not sure what the Camaro judging rules allow - have never seen anything published.
3694  Camaro Research Group Discussion / General Discussion / Re: small block vs. big block motor mount towers on: April 18, 2006, 11:37:29 AM
Are big block motor mount towers always different from small block motor mount towers?

The car is at the body shop now and a 402 big block is at the shop right now getting done and I was wondering if we need to ordeer big block motor mount towers OR if there is a chance the ones currently installed will work.

Yup, big-block towers are different - they move the engine over about an inch to the right of car centerline for clearance to the steering gear.

Ed, almost all midyear Corvettes used the 1119515, and I've never seen a production 515 with anything but a screw-attached cover; have never seen one with rivets.
3696  Camaro Research Group Discussion / Originality / Re: 69 Camaro Z/28 front sway bar and power steering bracket on: April 16, 2006, 09:51:05 AM
There were five over-the-counter front stabilizer bars available, from 3/4" to 1-1/16", and there were five over-the-counter HD springs from 500 to 777 pounds per inch; the 3935784 was among them, and has a load rate of 615 pounds per inch. The 15/16" stabilizer bar was P/N 3962797.
3697  Camaro Research Group Discussion / Decoding/Numbers / Re: Hurst shifter,shifter boot on: April 16, 2006, 09:40:13 AM
None of those numbers match up with the numbers for any of the boots/seals used on '69 Camaros; may be aftermarket parts.
3698  Camaro Research Group Discussion / Restoration / Re: 68 Trunk Lid Emblem Location on: April 15, 2006, 02:39:12 PM
Don't know if '68 is the same, but my original '69 spoiler Z/28 has the bottom edge of the "by Chevrolet" bar 1-1/4" forward of the edge of the spoiler, and the outboard edge of the bar is 4-1/2" from the edge of the deck lid.
3699  Camaro Research Group Discussion / Maintenance / Re: One More 68 Electrical Challenge on: April 13, 2006, 01:01:59 PM
Sounds like you've got an open in the main power distribution circuit; not sure if '68 is like '69, but power is fed to the fuse block from the battery via a pigtail (from the + battery terminal) to a plastic junction block behind the battery, then from there to the horn relay, and from there via a big red wire into one of the multiple connectors on the engine compartment side of the fuse block. If the terminals in those connectors get corroded, resistance builds up (which creates heat), and the "big red wire" connection can go open due to partial melting/distortion of the cavity in the connector for that wire. I'd pull those connectors off and check the terminals for corrosion/misalignment.

The J294 is an internal scheduling code used only at Van Nuys; it's not related to the car's configuration.
3701  Camaro Research Group Discussion / Decoding/Numbers / Re: What? on: April 12, 2006, 01:06:55 PM
Must be the passenger car 350 - all Corvette small-blocks were built at Flint.  Smiley
3702  Camaro Research Group Discussion / Restoration / Re: Wiring harness snafoos! Help! on: April 11, 2006, 11:03:37 AM
I don't have a '68 wiring diagram, but those items are all fed from the accessory buss in the fuse block - I'd look for a bad fuse, bad fuse clips, or a bad connection inside the fuse block for that circuit.
3703  Camaro Research Group Discussion / Restoration / Re: Wiring harness snafoos! Help! on: April 10, 2006, 04:14:19 PM
Everything seams to be working except: wiper motor, heater fan, radio. I have tested these systems directly from the battery and the wiper motor, fan blower etc work. But there is no juice at the fuse block. Do these systems get there power only after the key is in the on position?

Yup, those items only get power with the ignition in the "on" position.
3704  Camaro Research Group Discussion / Decoding/Numbers / Re: Style trim group on: April 10, 2006, 04:11:24 PM
69's didn't have the bright belt reveal moldings - different body design that year.  Smiley
3705  Camaro Research Group Discussion / Restoration / Re: Passenger side rearview mirror location on: April 08, 2006, 01:24:20 PM
There was no factory option for a right side outside mirror in '67, but it was available as a dealer-installed accessory item.
