I suggested John Hinckley get involved because in the back of my mind I think I recall GM installing a chambered style under car exhaust... but on the early Z28 Camaro? Chuck is correct, the original RPO N-11 Corvette exhaust was nearly identical to original standard exhaust system except for...

uhhhhh, maybe John Z could help this thread a bit...

The genuine blank trim tag issue is interesting. If two have recently surfaced there are likely more somewhere. Genuine trim tags share specific common elements before factory processing. They became unique in many ways when they were coded and applied. A "genuine tag" may pass some initial...

Dave, thanks for the reply. The engine was finished when I bought the car in the early '90s The heads do not have the raised area between the middle exhaust ports, indicating to me that they are not late model. I never had the valve covers off so I don't know the numbers or dates. I...

I'm tuning up one of my 67s and pulled these plugs. It was breaking up upon acceleration over 3500 rpm. Just tooling along without dumping it ran fine. It is a 390 with AC and pings under load. Timing set to factory specs with stock ignition components. Plugs seem to indicate rich carb and...

Thanks for answering questions All I know is I hate bleeding brakes. Sounds like this rig is worth trying. I appreciate your comments. I have 4 midyears and use silicone fluid in all of them. Three have solid firm brakes. A pita to install and bleed, but finished with great results. I know...

Sounds like I need this tool. Just to clarfy, the additional tubing you bought was used in the traditional bleeder to jar hook up? Do you now have a firm pedal after hard braking using silicone (DOT 5) fluid ? Is this the answer to all the brake system stress I have been dealing with lately...

Used it yet? I am eager to hear about your actual use. My 66 racer just got a fresh rebuild of the J56 system and uses DOT 5. At 20 bucks a quart, I hate to use up a lot of fluid. The brakes work, but the pedal goes spongy after a hard run. Also just got done rebuilding and flushing one of my...

I am also interested in how well it works. How much fluid do you need to bleed the entire system?

Concave vs Convex For me the jury is still out on this one. As an active NCRS 200 Club judge and a NCCB judge, specializing on 1967 interior, I have looked at hundreds of cars. Unrestored examples I have seen (including one of my own) with U15 have had the lenses installed concave. Restored...

DOT 5 DOT 5 is the specification for silicone brake fluid.

Bleeding midyear brake systems with J56 and DOT 5 Using DOT 5, any expierience with a prefered system? Brake fade and softening pedal (no measurable rotor runout detected) seems to creep up after a session of hard braking. Repeating attentive gravity bleeding yields similar results. The master...

Example of dealer delivery date stamp on trim tag Above is an example of a Dealer applied delivery date stamp on a genuine mid year trim tag. It is random and somewhat carelessly done. I estimate that only a small percentage of valid tags have this stamping by the dealer at the time of...

Here are a few references to keep you busy. I have 3 four year old vintage style Delcos from Antique Auto Battery and they are working fine so far. I do trickle charge them with a battery tender during the winter months. Antique Auto Battery http://www.antiqueautobattery.com/ Black Panther...
