If i recall correctly he told me just 4 months ago that "athena's is what he was going to start pushing when we spoke on the phone. now rather these are athena's or not idk. i remember him telling me that as far as stock casting they would be lucky to make a drop more power than "stock" cylinders.
send me some dune ported cylinders and i will be be the "good news spreader" for southern oklahoma. 421 cylinders, crank, pistons and domes for a modquad. deal is sweet enough i will even purposely promote the cylinders
