I'm usually not a fan of this era Firebird, but this resto mod is really well put together.
Look under the front air dam for the first hint.

Beautiful!

 

[tiger roach]

That is a card-carrying BMF.

 

[BlackCat]

Not bad at all!

 

[Coralkong]

None more black.

None more shiny.

None more bad-ass.

 

[Tig]

I think I'd want to incorporate the twin hood scoop ram air for the turbos, but there might not be enough room to do it right.

 

[mongooz]

very interesting

 

[Guitar Heel]

Bad. Ass.

 

[Packerbacker]

Very very nice

 

[Tiltsta]

Awesome. I wonder what kind of power a twin turbo 480 puts out. 600? 800?

 

[dougk]

I'd be disappointed if it was anywhere under 900-1100 at the wheels.

I used to be friends with the Butlers back when I built Pontiacs. Rodney was one of the earliest v8 guys I knew who really took to turbo's.

 

[Steverino]

Hell yes.
