2000 Pontiac Firebird Trans Am

Named the Grease Monkey, the Trans Am was treated to a major rebuild, so I have divided the pages up into two sections, a historical one for the various things I modified whilst it was the “old” Transam and a new page for the full rebuild it eventually got… take your pick.

The spec of the original Trans Am when I purchased it was;
