Do we have a real SS in the garage?
« on: October 14, 2013, 03:45:50 AM »
Hi,

We purchased a 1969 Camaro off of eBay about two months ago... from all indications it appears to be a SS after reviewing the info on CRC?
Here's the specs, vin number and cowl tag info... is this a true SS?  any help or insight would be appreciated... thanks.

Specs...
350 small block, M-21 Muncie 4-speed, 12 bolt posi, multileaf springs, power front disc with rear drum brakes, power steering, center console with factory gauges, in dash 7k tachometer w/55k RPM red line, 2" cowl induction hood, dual fuel lines (primary with vapor return).
Note: The motor has been replaced with a zz4 crate engine with aluminum angle plug heads... don't know if the original motor was a small block or big block... the car sits a little high in the front so maybe the front coils were to support a big block?

Vin number...  124379N598xxx

Cowl tag info... ST 69 12437 NOR259593BDY
                         TR 723                   59 59 PNT
                              02B                   X11

If you don't have any origianl paperwork for the car, get the partial VIN stamping off the transmssion and see if matches the last 6 digits of the VIN of the car. You might post a picture of the stamp so the experts can confirm whether or not is an origianl stamp, or restamped. If it matches your car, is an origiinal stamp, and is a Muncie, it sounds like it could be an SS.

Small blocks got M20's, big blocks and Z28's got M20, M21, M22 depending on axle ratios. and engine combintations.

Mark,

     VT
From http://www.camaros.org/trans.shtml#4speed:
The wide-ratio Muncie M20 was available with any of the high-performance engines, except the L78 and Z28 in 67 only came with the M21. The M20 was the only 4-speed available with the SS350 and the SS396/325 hp (L35) engines.
The close-ratio M21 was available only with the SS396/350 hp (L34) engine and the solid lifter engines (Z28, L78, and COPO).
The heavy-duty M22 was limited to just the solid-lifter engines, starting in Camaros in 1968.

Ok, what was the reasoning behind not having the M20 as an option on those? I was told on another thread that running the M20 actually gave you a lower 1st gear, to low for the big blocks, and they would just spin the tires and not be able to hook coming out of the hole?

ok I get it, why was the M21 only available with specific combos then?

It had to do with rear axle ratio and an engine's useable RPM range.

Close-ratio is better when you want to be in the power band of the engine when you shift 3-4.
More important when racing, esp road-racing.
