Stop in for a cup of coffee

Big Daddy signature in 2008...

It says "Stage 1" on the side... There was no stage one, only stage II and stage III....

Engine size states 426 max wedge... In 62 the only max wedge was 413, no 426 until 63... So I doubt it is an original max wedge car but a clone...
Technically no.

but a lot of people seem to call the 63 413 max wedge engine the stage 1 version. Simply because the factory immediately called the 426 max wedge stage two in 63 and in 64, it was called stage 3.
