I built a motor patterned after the ZZ430 crate motor, but with a forged 3.5 inch crank, Childs & Albert 6 inch sportsman rods. TRW light weight racing pistons (411 grams without the wrist pin), fast burn heads and the LT4 hot cam kit. Also used a light wt Fluidamper and 14 lb flywheel. I used the dual plane manifold that came with the ZZ430. Thumbing through the '07 GM performance catalog (something I do waaay too much) I noticed the Vortec Eliminator 12496822. Will this make my fall flat until higher RPM or would this be a better choice? Any body running this setup?
