Was the 455 engine an original option on the 66 Lemans Convert or was it just in the GTO?

Pontiac introduced the 455 in 1970. They introduced the 400 in 1967. I would guess the LeMans could be had in '66 with the OHC 6-cylinder and the 389 V-8. I'm sure others can chime in on what else may have been available.

Jeff, 389 was GTO only. The LeMans could be had with the 230 cu in OHC six or a 326 V8.
No 455's until '70 as said.

The '66 Lemans Conv. could have the 326 V-8 engine,the OHC-6 2 bbl engine or the OHC-6 Sprint 4 bbl engine.I have an original 1966 brochure showing the different engine combinations.I believe the 350 engine first came out in 1968.
