I have a 69SS with a 255hp 350. (interior code 714, paint code 76 B) The motor appears to be original to the car. The car has not been restored. A friend with several first gen cars told me that he once read that a small number of SS350 cars used the 255hp motor. The car was assembled in the 5th week of August. I am unable to read the partial VIN by the oil filter. Eventually I will pull the engine as I restore the car and then will know for sure. Does anyone have any information on this? Thanks in advance.

What you have is an LM1.

From the 1969 PAGEon the CRG site:

The LM1 moderate-compression 4-barrel carburetor 350ci engine was introduced at the beginning of the 1969 model year as the replacement for the L30 327/275HP engine. The LM1 was, in turn, replaced mid-way through the model year by the lower-performing L65 2-barrel carburetor 350ci engine, and most of the higher performance features of the LM1-equipped vehicles were not transferred to the L65 units. Even more so than with the L30/M20 in 1968, it was possible with the LM1 to create a SS-350 look-alike in most performance features. The absence of SS badges and SS hood/hinges, both easily added, are the only easily distinguishable clues between a L48-powered SS-350 and a LM1 with added J52 disc brakes, N10 dual exhaust, D90 stripe, one of the 70-series tire options, and the Z87 custom interior (which provides hood insulation). Closer examination of the original engine is required to note the lower compression heads, the distributor code, and/or the engine application code. The 7-inch SS wheels were also not available on the LM1/M20.

Try for more LM1 info.

But something's not right. LM1's were early cars. 714 interiors were late.

Can you post the tag info and engine code?
