well... not to put too fine a point on it but there was a big block chevy in 62.. 348/409/427 and.. there was a 3 speed turbo trans... you could also hook up trannies from other cars.. I had a 47 chevy coupe with a B&M hydro full manual body.
I believe the car in two lane blacktop had a 4 speed in it when the movie was filmed.. the turbo was added later.. could be wrong.

I had a 409. It was a 1963 409/425. The 427 version came in 1963, it was known as the Z-11. It was not the same as the 427 in the 55 Chevy. It was NOT a big block. It was a "W" motor. It shared main bearing spacing, rocker arm ratio, and valve sizing with the later introduced (1965) big block. Even then the big block introduced in 1965 was a 396, and not a 427. The crankshafts, oil pumps, and rocker arms can be interchanged, but little else can. Having owned both a 409/425, and now racing a 427/425, I can tell you they are cousins, but they ain't brothers.
The old Hydramatic transmissions had little in common with the 400 Turbo-Hydramatic, introduced in 1965. There were some "pull ahead" versions of the 400 installed in 1964, in come Cadillacs.
The black 55 Chevy used for the movies was built by Joe Reath, and had a 427 Chevy with a Weiand tunnel ram and two 660 cfm Holley carburetors. The transmission was a 400 turbo. There were a couple of 2nd and 3rd unit cars built for filming, including the one that was wrecked at the end of American Graffiti. The "star" car that is seen in most of the shots has an automatic in it. There is of course "Foley" sound in the track that is a recording of a 4 speed car, and there are interior shots of a car with a 4 speed. There MAY be 2nd or 3rd unit shots of a car with a 4 speed in it.
