16  Camaro Research Group Discussion / Mild Modifications / Re: 8.2 10 bolt differential on: December 19, 2013, 08:30:09 PM
Mr. Norton brings up a good point in using an auto trans as the power application is more forgiving than 'shocking' the driveline with a clutch, aka, 5000 rpm clutch dumps.
I had a 8.2 inch diff in a '67 and moved it over to a '68 when I was drag racing.
It lasted 9 years/seasons running a 350 CID/PG/4.11/ 2900 lbs at an et of 13.40's using 28X10.5X14 slicks and traction bars with the snubber under the front spring eyes.
Then the carrier split. I smiled as the diff didn't owe me anything, I got my money's worth.
Driving technique is the key.

I would try another known good battery, maybe one from a daily driver, before discounting the VR reg.
Ensure the ground strap from the mounting bolt of the mech VR is also in place with the new VR.
Might even try a separate ground strap from the new VR chassis to the alt case for an experiment.

Usually, throat is the term defining the working distance from the anvil to the main structure of a press.
Think of a C-clamp, it has a movable anvil and a stationary jaw/chuck supported by its structure, aka, backbone, lack of a better term.
The 'throat' is the distance from the anvil and chuck/jaw to the backbone.
Bigger C-clamp, bigger throat.
19  Camaro Research Group Discussion / Maintenance / Re: Excessive Amperage Draw on: December 14, 2013, 07:47:10 PM
Agree with most answers given. The OE ammeter is a millivoltmeter measuring a voltage drop on a length of wire.
The OE ammeter is merely an indicator, no quantitative measurements, read calibrated, can be trusted.
A true ammeter measures the current draw to/from the battery.
A suggestion would be installing temporarly an ammeter with an internal shunt, a cheap -50-0-+50 ammeter from Harbor Freight, catch on sale for $10 or less, can be wired up to the two leads on the battery junction block. Hook up ammeter, turn on lights, gauge reads towards the charge side, reverse the leads.

With 25 amps indicated all the time, it may be a bad battery cell - swap a known good battery and compare results.
After a normal engine start, with OE designed circuitry, it would take about 15-20 miles of 2000-2500 rpm to recharge fully
Also, with 25 amps, it is getting close to the max output for a 37 amp alternator. I would imagine the alt case is hot to the touch.
Tip: with a 50 amp range of the HF ammeter, you could hook it up to the alt BATT stud and view the action.

Welcome to the Club and congrats on buying the correct year.
Reapinting back to the original color is worth a buck or two, as Corvette Bronze was very few and far between.
Verifying a '68 is kindda hard, but having documentation helps, and more important is the POP plate as it has 'born with' options listed.
Other here more pronounced, will help answer your questions better than I can as I am learning from the experts here.

Does the 'Mother-In-Law' chair go with the blue Camaro?
22  Camaro Research Group Discussion / General Discussion / Re: 68 Z28 on the CRG Home Page on: November 13, 2013, 08:25:46 PM
I agree, beautiful Camaro.
Thanks for the pictures.
23  Camaro Research Group Discussion / Originality / Re: 69 Z28 passenger exhaust manifold pic on: November 11, 2013, 05:21:08 PM
One '68 327 I had, had the weight parallel to pass frame rail with counterweight to the front.
I would think the valve would be universal fit as it would match manifold ID.
A '64 Impala 327-300HP, ram horn manifold had the weight to the rear of manifold.
24  Camaro Research Group Discussion / Originality / Re: 69 Z28 passenger exhaust manifold pic on: November 10, 2013, 03:09:55 PM
In Post 3, the side shown mates with the manifold via a gasket.
The bevel side underneath, mates with the exhaust pipe donut.
25  Camaro Research Group Discussion / Restoration / Re: Re-coding an original door lock on: November 05, 2013, 12:11:08 AM
No, if you look at the ends of the ign key and door key, one is a mirror image of the other key.
Ign key does ign switch and glovebox, door key does doors and trunk lock.

27  Camaro Research Group Discussion / Restoration / Re: 327 Timing Chain Cover on: September 06, 2013, 10:27:40 AM
I believe you will need the one style with the welded on scale as opposed to the bolt-on scale.
28  Camaro Research Group Discussion / Originality / Re: Correct starter for '67 - 327 on: August 19, 2013, 08:20:50 PM
Small ring gears, 153-tooth, 12.5 inch(?) used the straight-line mounting bolt starter.
Large ring gear, 168-tooth, 14 inch(?) used staggered mounting bolt starter.
Starters with a copper extension between the solenoid and motor terminal are heavy duty starters, more torque.
Standard duty had no extension.
29  Camaro Research Group Discussion / General Discussion / Re: Neutral switch - that could have gone so wrong :-( on: July 11, 2013, 07:37:23 PM
Both designs, whether top of the steering column at the firewall, or on the console shifter, the switch is adjustable.
Loosen the two screws securing the switch on the sides and adjust accordingly.
Make sure a PO did not jumper the two purple wires together or rewired the solenoid control wire independently of the neutral safety switch.
