The Blitzkrieg series of heads will take the big block street/strip market to a new level. BRODIX and Jesse James have come together to create the JJ 294 and the JJ 270. These heads offer unique features such as a black hard-anodized finish and custom Jesse James™ embossed logos. Standard features include a 294 cc or 270 cc intake port size, A-356 virgin aluminum, bulletproof rocker stands, and ends milled and drilled for accessories.
