1970 Pontiac Firebird Twin Turbo 1200HP Build Project

Builder: tcronkright

As a new member to this community I am excited to introduce a project I am working on in connection with the guys at All Speed Performance in Muskegon, Michigan.

We were shooting for 1,500+ hp and 1,300+ tq at the rear wheels and by the looks of the Butler Performance IA II performance 400 block bored to 475 cu. in., Kauffman heads, Eagle crank that has been turned, Ross custom forged pistons with 8.5:1 compression ratio, they’ll hit the mark.

This will run on pump gas. Visner Engine Development made a custom billet intake with matching two-piece billet valve covers.

Kris Horton spent countless hours on the rendering bringing this vision to life. Some of body modifications include a custom chin spoiler, rocker skirts, enlarged functioning hood snorkels, functioning fender vents, recessed roof and trunk lid, integrated spoiler with center indentation, rear valance with diffuser and widened front and rear fenders.

For performance, we started with a custom Pontiac 400 block, punched it to 475 cu in. and are adding hi-flow Kauffman aluminum heads, twin turbos and custom pistons…
