Maintenance / Re: ideal 4053 jetting for stock 302/30-30/manifolds

Aaron,
the lash would be better set at .026"/.026" with stock stamped rockers.  You will be off the clearance ramps (more clatter and wear) if you use the .030"/.030" setting. 

-Mark.

An EXCELLENT article on that topic (thank you John) is here...
http://www.camaros.org/302valves.shtml

The “old school” way I was taught - with the 30/30 cam and others was to set them hot and running. But there are better ways than that.

Excellent suggestion. I wonder if the (aftermarket) reproduction camshaft I used in my '68 MO engine will respond to this. Supposedly a dead nuts ringer for the OE grind. I am using long slot 1.5 stamped rockers -

Regards,
Steve

According to the options spreadsheet, RPO U73 Antenna, manual, rear mount, was only available with an AM radio.  All the AM/FMs RPO U69 or U79  had a front mounted, fixed height antenna mast

I guess I have a very rare 68 for according to the protect-o-plate it cam with a am/fm radio and the antenna is in the rear.

Adjustable or fixed mast ?

People were usually split, depending on what they were exposed to early on. Both Starrett and B&S were first choice for most toolmakers and tool and die guys, maybe leaning towards B&S in the earlier days for me. I remember being horrified to see "Made in Japan" on Mitutoyo tools when they were first introduced (to me), but the quality sold a lot of people on the line.
Boiled down to personal preference -

If you are running a stock exhaust system, do you have the stock warm-up valve installed ? Operable ? Also, look closely at the oil drain passage at the end of the head, make sure you're not damming up oil around the valve when the engine is running. High volume pumps have a tendency to put a lot of oil where you don't really want it to accumulate.

I sold Starrett, Brown and Sharpe, Mitutoyo, Fowler and others for years, I can remember the first digital caliper I ever saw (believe it was a B&S), cost was unreal. Now you can buy the cheap versions for $15.00 on sale, and they work for what you need them to do. Break 'em or lose 'em, go buy another.

Mike's right, surf eBay and pick up the great older tools for a fraction of what they sold for, and treasure them. Use the cheap ones for field work -

General Discussion / Re: Opinion on 1100814 Alternator stamp
« on: August 08, 2018, 02:42:09 AM »
the depth, font and spacing mirror the original that was sold earlier.
Have another close look.

I should have put them side by side - there are some differences, but the similarities in the varying depths of the 1100814 stamping are danged close. Different fonts could be because of the date gap; I'm not trying to legitimize it, but it's pretty good at first glance. Still, a lot of money for an unknown without documentation.

Careful, Tim - us Tennessee boys stick together - ask Cook. I do know who you are referring to, though - lol.

I'd say it's a dang good restamp if it is one - the depth, font and spacing mirror the original that was sold earlier.

I'd have no problem using it, but would prefer some kind of documentation for that wad of pesos -

General Discussion / Re: Muncie trans question
« on: August 07, 2018, 03:42:34 AM »
My '69 M20 broke the clip under the shaft gear, and proceeded to jam the reverse selector with the remains of the clip. Goofy design to be sure - the spring clip fatigues over time, and becomes a problem. You'll have to pull the tailshaft housing to correct it. There are several options to replace if the gearset and clip are like my '69's problem including ones like this :

https://www.ebay.com/itm/MATCHING-SET-ALUMINUM-MUNCIE-POWERGLIDE-SPEEDOMETER-SPEEDO-GEAR-COMBINATION-KIT/192617012588?hash=item2cd8de5d6c%3Ag%3AWw8AAOSwal5YG1BZ%3Asc%3AUSPSPriority%2137087%21US%21-1&_sacat=6028&_nkw=Muncie+speedo+clip&_from=R40&rt=nc&_trksid=m570.l1313

Not terribly difficult, but a pain in any case. My gear was metal, not plastic, and I reused it. Clip was sourced from GM, and yes, you'll really need to pull the trans as it will need some wiggling to clear the tailhousing from the reverse gear selector. Do yourself a favor and don't try to drive the staking pin out of the reverse shifter boss on the tailshaft - the (tapered) pins are usually frozen in place by this age, and you'll bend them or mangle the tailshaft housing if you try to pound them out. With a little creative wiggling, you can disengage the selector from the slider and pull the tailshaft housing clear. Actually a fairly quick process, discounting the fact you have to pull the trans.

Decoding/Numbers / Re: DZ block on craigslist
« on: August 03, 2018, 10:27:55 PM »
Likely not glass beads, but shot blasted or shot peined. Glass or media is not aggressive enough to do that much damage.

I'd bet the hole in the deck was someone's attempt to make sure he got his block back from the machine shop. I used a couple of letter stamps in an inconspicuous place on my heads when rebuilding in the 70's, just to make sure I got back what I took in.

Seems to be what he describes, pricing is fair for what the car is (if the block stamping stands up).

I really like the guy's humor in his ad - read the first line of the second paragraph of the description. I needed a good laugh -

I'm considering going to the garage and hugging my Z11. Someone ought to let the air out of this one -

Where's the pic of the VIN in the ad ? Or did someone have a separate ?

That's great -

General Discussion / Re: Best way to sell my car?
« on: July 21, 2018, 12:06:01 AM »
Resist the urge to sell and hang on to it ! My youngest is about to leave the nest this September: I've had three through college, two are now married (daughter's wedding is just now getting paid off), youngest son gets hitched in September, 1st grandchild was born June 23rd., and on it goes. I've fielded many offers, tempted to sell one or more, but I could never face the fact that when and if they sell, I could never replace them. Too many stories from folks over the years about seller's remorse when they let one go out the driveway. I have only sold one of my cars since '73, a '70 LS5 SS, but that was because my best friend was selling his '68 BRG Z that I had helped him buy, and build up - I couldn't let it walk. Bad feeling to watch the trailer leave the house after owning the Chevelle 19 years, only I had one to replace it, which helped somewhat. Borrow money, get a second mortgage, sell something else to retain it, but I feel it will leave a 3 foot hole in you coming out the other side.

Just my opinion -

Decoding/Numbers / Re: Caveat Emptor - Future Rebody of 124379N511823
« on: July 16, 2018, 12:11:00 PM »
High side of ridiculous. Add a $13K Dynacorn body, $10K drivetrain, and you still don't have an original car. If I had $30K to spend on a Camaro, I bet I could find a good original car to sink that money in and have some left to boot.

I'm surprised the dash is still intact. I've seen cars from the rust belt that even dissolved the dash far enough back to take out the VIN area.

Steve
