I was asked to post the info of my Norwood Z11 last night so here it is.

ST 12467 NOR293396
TR 720 50 A PNT
03D Z11

Car has a M20? double groove spline, 660 case, A replacement Dated Non Vin 272 Block 396/350 hp engine. Has the orig BB redline tach, 621 bell housing, Orig GM Engine frame towers, orig BS coded and dated rear. Can't remember the date or other #'s on the axel. Car has console, gauges, tach, clock, manual top, rear guards, head light washers, tilt, endura, am/fm Blue light, auxiliary lighting and rust in the rear Qtr's. Are there any other tips to prove of true BB authenticity? I tracked the car down through three different owners and they all said it had the BB engine in it when they had it. The car came from Maryland as far as I can tell. Last owner had a Maryland title. which I still have it in. Cas has had drivers side Qtr repair and a drivers front fender has been swapped. No other signs of damage any where!!! Still has the Blue Vin sticker on the back side of the door.

Of course anything can be changed, but you have already uncovered many of the clues that lead you to believe it was originally a b/b. (tach, 621 bell housing, motor mount towers) I'd check the heater box in the engine bay. On B/B, the heater hoses entered and exited throught the center of the box. (s/b were at the inside edge of the box) Also, the power steering pump is slightly different. I forget exactly how, but the return line tube on the resivoir is bent differently...maybe someone can describe differences. The b/b z-bar is 9 1/2" (9" for s/b) and the clutch rod adjusts with a square "nut" with a pin on it, rather than an L-shaped female threadeed tube. In addition, the shifter bracket holds the shifter out further from the tailhousing.

Also, the fan shroud is unique to big block..and the upper attachenet is a small 3/4"x3/4"x2" (estimate) stamped steel angle. The small block used a 2" wide by 6" long L-shaped bracket. I've seen quite a few b/b shrouds with the s/b bracket.

All of these can be changed, but most probably wouldn't have been, if some hot rodder changed them out in the 70's.

Get Rick's catalog (800) 359-7717 for good pics. (also good place to buy parts)

Tom what is the VIN on your car?

The blue VIN label is a repro. The feds did not require it until the '70 model year; Norwood started using it around build date 08A.

Vin is 124679N6230xx. I don't really feel comfortable about giving out my Vin over the net, so I gave you guys enough to keep me safe. Sorry. Yes the car has the BB heater box, Sorry I forgot to include that, It did however come with, but not installed, a orig GM (near mint) sb fan shroud with an AC sticker on it, but the rad support has a kinda rusty bracket that looks just like the item on the bottom Page of Rick's catalog (page 188) part# EP-11, the BB upper bracket. Thanks, I never knew any thing about this http://www.camaros.net/forum/smile.gif About the linkage, I never new about this either. I'll have to check. I would have thought they were the same??? Yes it also has the weird shaped Hurst mounting bracket as seen in Rick's unlike the sb unit you see on Ebay every once in a while for the sb units. I thought I had the wrong unit in place and thought I needed the Big thick mounting plate I sometimes see at the swap meets. Good thing I didn't "off" this pc. My other car, I did, and now the shifter hits the console every time. (It has the sb unit)Oops, I forgot to also mention, the car has the BB style manual shift crossmember which I had to replace. It was a bit twisted http://www.camaros.net/forum/frown.gif Bottom hole has the big opening with an 45 degree angle on the one corner. I had NO clue about the sticker. Thanks for the heads up on that. I was going to try and save this if I could.. But guess I can go with a Repro unit here. Are these mandatory now? Who types in the vin? Can I do this or does DMV have to do this?

The reason the brackets and linkage are not the same is because the b/b is shifted to the pass side of center. Therefore, so that the shifter is in the right place, it uses the special shifter bracket. However, that moves the shifter further out from the tranny, so slightly different linkage is needed, to avoid binding.

The engine location is the same reason for the special crossmember, and why the z bar is longer. Why it uses a different clutch rod assembly is a mystery to me. (see Ricks page 82 CL10 and CL45 for differences) by the way, the L-6 uses the same swivel as the big block, but the rod is somewhat longer (like 1" to 1-1/2" longer, if I remember correctly)

The VIN label is curious, though. William is right about it being incorrect for a march car.

Of course, there are no guarantees, but I'd bet yours left Norwood as a big block. The 3 previous owners statements are key...especially if they date back 10 or more years.

Everything we have discussed as clues to b/b are bolt ons, and easily changed, but it is unlikely that someone would have gone to the trouble (or even known what's correct) 10-15 years ago.

Your news is reassuring http://www.camaros.net/forum/biggrin.gif Are there any other little things you can think of to prove this car defiantly a true BB car?

Sounds like your car is a 6 cyl model based on your VIN (the fourth digit in the beginning of VIN, this being a 6 which represents a 6 cyl whereas a 3 would represent a 8 cyl. Check the VIN on the inside of cowl vent located on the right side of the car and see if it matches your VIN.

Robber, his VIN is correct for an 8 cylinder convertible-12467.

Robber, sorry but you are way off base here...

Do you guys think I would be destroying this car if I added a Factory AC set up in the car. I have everything to do so except for the BB AC Brackets. Everything is Orig correct 69 BB Chevy. The firewall section and duct work, wiring, and bezel is from a 70 Nova. I want to keep cool and dry down here in sticky GA, but don't plan on being here forever either.

Tom, it's your car, you gotta do with it what you want to!

What is the two letter code on the radiator?
How about the fan/clutch assy, original?

Also the big block had different front springs, have you looked to see if the tag may have survived on one of the springs. My car has 72,000 miles and found one of the tags, also mine still has the original spiral shocks on the front end.

Hi Tom!
Sounds like a BB and that it was restored once (via the door sticker which you don't need to replace).
What's the trans code?
What's the redline?
1 or 2 fuel lines?

On the AC, adding it's a PITA (Mark, you can speak up on this)! And that's why you should have the top down!

If I were adding A/C to a non-A/C car, I'd go Vintage Air. That way, if you ever change your mind, you can put it back as original.

'69 cars that originally came with the blue VIN sticker will have a different door. It's real obvious when you see them side by side. 8/69 and later.

The Rad has been swapped out for a new Four core manual shift style as well as Fan Blade. Has a Chrome/black Blade and No stickers on the springs. Is missing Cowl induction set up.

My apologies for the mistake. Was feeling under the weather and didn't realize I misread the wrong code (was thinking the third digit).
