Re: 1979 PONTIAC TRANS AM Y84 L78 400 4SPEED
The 400 in our '72 Lemans Sport was designated as L78 in the GM documentation.

[ QUOTE ]
So, L78 is the RPO code for the 400 engine in 1979? [/ QUOTE ] Yes. The Pontiac 400, not the Chev 400.

Re: 1979 PONTIAC TRANS AM Y84 L78 400 4SPEED
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.

I had a 78 L78 M21 car and let me tell you, it was one fun car. Whoever buys this car is going to love it! And it's a rare one as well!

My 78 was documented with a Muncie.

I have one of these cars. Yes, they got the Borg Warner Super T-10. This car runs, lots of fun. It was my college car, lots of good memories! I could beat anything on the street until that Mustang 5.0 came around in the mid-80's and gave me a run for the money!
