1969 LM1 Convertible

Here are some pictures of my 1969 Camaro.

This is an all number matching convertible camaro.

It was originally Dover White with a black top and black standard interior. This is verifiable by looking at the trim tag mounted on the firewall:

On the first line "69 12467" means 1969 V8 convertible.
On the second line "711" means black standard interior, "50" means Dover white body color and "B" means black top.
On the third line "09B" means that the car was assembled during the second week of September 1968 which corresponds with the rest of the dated components on the car.

It has the original engine which consists of:

Part	Casting Number	Casting Date	Description
Block	3932388	Date H288(August 28, 1968)	This is a 2 bolt main small block.
Heads	3932441	Date H278(August 27, 1968)	These heads are 1.94/2.02 int/exh and 76.26 cc.
		Date H298(August 29, 1968)
Exhaust	3932376	Date H248(August 24, 1968)
	3942529	Date H138(August 13, 1968)
Intake	3927184	Date H238(August 23, 1968)	This is a cast iron manifold for a 4 barrel carb.
Carburetor	7029202	Date G8(July 1968)	This is a 750 CFM quadrajet carb.
Distributor	1111955	8H23(August 23, 1968)
Water Pump	3927170	F68(June 6, 1968)
Alternator	1100834	8H26(August 26, 1968)

Here are some pictures of the casting numbers and stamps:

The engine pad stamp is 508926 T0830HS. This means that the engine was assembled in Tonawanda on August 30, 1968 and is a 255 horsepower 350 with a turbo 350 transmission. The 508926 is a partial VIN that matches the last part of the vehicle VIN.

The engine isn't exactly "stock" anymore as the following modification have been made:

The block has been bored .30 over.
The stock camshaft has been replaced with a competition cams XE262.
The exhaust manifolds have been replaced with a set of Dynomax headers.
The stock distributor has been converted from points with a Pertronix Ignitor kit.
The stock coil has been replaced with a Pertronix Flame Thrower.
The stock water pump has been replaced with a high performance pump.
The flex plate has been converted from a 12.75" to a 14".
The starter had to be changed due to the flex plate change.

The engine puts out about 300 HP so it's not a beast, but it's a nice cruiser.

The transmission is a turbo 350. The only numbers on the transmission are the partial VIN stamp which matches the last part of the vehicle VIN.

The car originally came equipped with a 3:08 non posi 12 bolt rear. This is verifiable by the axle tube stamp and the center section casting number:

The stamp is BL 0830G1 which means 3:08 non posi(BL) assembled during the first shift in Detroit on August 30, 1968(0830G1). The casting number 3894860NF means 1967-1969 Camaro 12 bolt rear.

I removed the original 350 and TH350 and installed a 383 stroker and a 2004R. Here are some pictures of the new engine:

The new 383 is a 4 bolt main block with a 4.030 bore with a 3.76 stroke 400 crank. It has has edelbrock performer RPM heads(70cc) and intake with 10.65:1 compression. I rebuilt a QuadraJet 7029223 carb to use on the 383. I rejetted the carb with 50 metering rods and 73 jets. I also installed a GM HEI distributor with a 50,000 volt coil. I used a GM L82 grind for the cam. The specs are lift .450/.460 Dur 224/224 at .050 with a 114 lobe center.
