[forcefed3.8's]

The Chevy 3.8 (229), 4.3, and buick's 3.0, 3.3, 3.8, and 4.1 are 90° V6's. The new 3800 blocks are way stronger than the 109 block. 8445 heads will not bolt on a new engine. The new 3800's have a mass air flow sensor. It is built into the TB on the Series 2's, and separate on the Series 3's.
