Mark, I am pretty sure the L72 was not available at all in 1967 Impala....

My understanding (with some new info this past weekend from Donny, perhaps?) was that no L72 cars were built, although a few engines were built. This was due to the plan of having the L71 available till GM's ban on multiple cabs on its passenger cars.

Yeah, I have had a few leads in the past on 67 L72 coded big car blocks, but they never got anywhere. Check out this scan I made out of the 67 owners manual a while back showing a 6000RPM redline tach. Kind of makes you wonder!

Did either or those options include the F41 suspension?
Here is a photo of my car at the Richmond NSRA car Show...
It is a 1966 Belair 2 door sedan "post car" that has F41 suspension ( and 427 station wagon springs on the front )the F41 suspension was suppose to have come off an "original 1967 427 Impala" that the body was rusted out.

I'd have to say that there would be a high probabilty of a 1967 Full-Size L-72 427-425 HP car. Colvin's book lists an engine suffix for 17 possible engines shipped from Tonawanda, so maybe a few did see the lot of day. Another interesting fact is that the L-72 was available in 1966,1968 and 1969. Just seems strange that they would skip a year. I tell 'ya, those L-72's really are something else. I know people like to talk about L88's and all, but a well tuned L-72 is just one heck of a street engine that will tear your head off at the drag strip on Saturday night, but still well-mannered enough to drive to work 5 days a week. I'll take mine in a '66 Corvette, thank you! That just has to be a brutal, dangerously fast little Musclecar!

F41 was never included with any package. F40 however was included in certain packages like station wagons and Z24s. The stance of that Biscayne is sweet! Are the rear springs originals?

Guess I have to weigh in lol .. when you ordered a SS427 you no longer were buying a Impala as all Impala nameplates were removed they wanted to draw attenting to the engine with this package. There actully was a few SS427`s that left the factory with "Impala SS" fender badges apparently by accident they were early cars and only a handful were released. Another tid bit is there were only a handfull of Imapala SS with the 385hp 427 ever made I have heard 15 - 20 as it was a special order and not publicized as there did not want to step on the toes of the SS427 RPO. Officially the last year for a full Impala SS assemblly line was 1968. in 1969 they did exactly what the previous poster said slapped badges on a run of the mill impala on the line and called it a SS Impala .

As for the L-72 I have read it was suppose to happen but never did no car has ever been found or paper work to support it. There was a Tripower set up that was also going to be available and when the vette boys heard about it they put the kabash on it .. They only wanted tripowers on there precious corvette .. The engine is in the build manual with a cancelled stamp on it .. it did not denote as L-72 I believe it was L-68 I found this.

And from everything I have read and seen RPO F41 is heavy duty front and rear susp. You could order this on almost any car if you wanted it just like ordering the 427 in a Biscayne in 67. This one is an original restored White with green guts,,
