General Discussion / Re: Main Caps
« on: March 31, 2022, 12:48:15 AM »
I personally know of one locally, February car, non-SS with a 3956618 four bolt nodular main cap original block on board - car was destined to become a stock class racer, engine was removed and disassembled and ultimately sold - I was amazed to see the Feb dated block, four bolt mains and nodular to boot, was not marked as an L48. All dates aligned with the car, owner/racer was unaware of the significance of the casting code. To me. it proved that sometimes things got a little mixed up on the production/assembly lines.

"Most" high performance engines used nodular main caps (which for small blocks in '69 meant 4 bolt main blocks). 4 bolts were used for the higher performance units primarily for strength and warranty considerations  - although I have seen the occasional lower horsepower (meaning below 300) blocks with 4 bolt mains and nodular main caps. The letter "N" cast into the cap denotes nodular construction.

Never seen a two bolt in '69 or later usage with a nodular cap - '67 and '68 two bolts used them for the Z engines, and L48/L79's as far as I know. Considering GM, there could always be the occasional slip during engine assembly with an HP block making it into the less-than-H-Perf assembly applications.

Ran across this website when searching locally for (TN) platers - searchable by state and industry type, I think there are 3189 plating companies listed here, along with companiy profiles and capabilities.

Here in TN, I've used Advance (formerly in Nashville, relocated to Portland) for bumpers and guards (they are really good, a bit pricey, offer both OE style and show chrome), Tri City in Elizabethton, TN (unbelievable core stock, will exchange or chrome plate yours), S&H in Nashville/Madison, TN - really good work, very reasonable and fairly quick turnaround). Sure are a lot more than I expected to be left in the US,

Powder coating and some anodizing companies listed here, too -

A question - why go to the expense and trouble of doing a resto-clone, advertise it as something it really isn't, and then attach the trim tag with rivets recovered from the Titanic ? I just don't get it - anymore than the local guy that attached his "X" tag to his "Z" with wood screws.

No comprende -

By all means, post some pics and/or docs. Z11 BB's are pretty scarce, a Z11 with a documented L78 would be rarer than hen's teeth. I'm not saying it's not possible, but it would be a true keeper -

What aftermarket manufacturer and seller did you source from ? My first suggestion is to find a good core and rechrome the OE piece, but hopefully there are multiple aftermarket sources. All of mine are OE, I'll keep it that way.

Post the VIN and the moderators might take a peek at the database to see if it's surfaced here before. More than a few black Z's have been discussed on the forum over the last many years -

Heartbeat has the 2 piece assembly in stock for about $170.00 (imported, all grey cast iron, but pretty darn close). You could use them, or bolt the rotors up to the original nodular iron GM hubs if you have a set. At least that gives you the appearance with the functionality -

Have you ever tried Light Image Resizer ? i used the free trial download for years, and finally bought the latest license to use permanently. It's effortless to send the pics from my iPhone (which usually formats the pic too large for CRG rules) to my laptop, resize the pics, and pop them online after saving to my Pictures file for future use. You can use the LIR to save the pic in any format and upsize/downsize you need, easy even for an old geezer like myself. I never trusted Photobucket, for the aforementioned reasons. Glad I didn't -

Decoding/Numbers / Re: Another Trim Tag
« on: March 05, 2022, 02:12:09 AM »
Pretty selective for a sandblaster or media blaster to deform only the lines it did. Maybe an attempt at hiding something, body sequence number and paint codes ?

General Discussion / Re: 1969 Z28 how many in this color combo?
« on: March 05, 2022, 01:57:15 AM »
Shame there's no good pic of the trim tag to verify authenticity. Wonder if that's an aftermarket fiberglass hood on the car - sure does fit poorly. If it is an original, I can see why hood pins were often a part of the deal. Those puny springs they installed on this one are a dead giveaway, outside of the fit.

A little too "crisp" for me - but that's just my opinion.

1969 - Orphans / Re: 69 L-78 JL 9Nxx3691
« on: February 22, 2022, 02:03:12 AM »
Going to be hard to tell no matter what - the gang stamp was angled due to the gate or riser where the "9N" started on; the first two in the sequential VIN couldn't quite stretch far enough to contact the block. If you get a better shot of them, please post it -

Don't paint it - read this thread and look at the results from the OP -

I've restored a couple of "cheap" OE shrouds - easy to make them look like new with a little TLC -

Restoration / Re: 69 L48 Throttle Linkage
« on: February 10, 2022, 05:27:45 AM »
Probably has multiple applications. There are two part numbers that fit the description in the parts book (included), no mention of transmission control or Powerglide on this number. Sketchy description, though - anyone have an earlier listing ?

I included two views of the same page just in case the resizing made it a little small.
