That's Pontiac's 1979 version of L78 which was the designation of the Pontaic 400 engine. Actually they used it for a number of years in the late 70's.

It doesn't mean 396/375hp.

So, L78 is the RPO code for the 400 engine in 1979?

The 400 in our '72 Lemans Sport was designated as L78 in the GM documentation.

Yes. The Pontiac 400, not the Chev 400.

Those '79 Trans Ams with the L78 were really quite a car and ran very well. If I remember correctly, the 400 Pontiacs were 4-speeds, and all the Olds 403's were automatics. Pontiac even snuck a nice camshaft in there and got away with it. You know, when the musclecar era ended in the early seventies, it's like someone forgot to tell Pontiac. Just take a look at the 1973-74 SD455's. What else was even close to them. Regular 455's were still available in 1976 and the WS6 four wheel disc brake cars in the late seventies, early eighties were cool. I mean really, how can you not like that engine-turned metallic finish on the gauge cluster. Great car.
