Looking for good fuel economy and performance on demand with a great performance look? Bolt one of these custom Holley carbureted tri-power packages on your small block today. They come fully assembled and have been custom dyno tuned on a GM Performance ZZ4 350cid crate engine. The dyno test yielded 346HP @ 5200RPM which resulted in a gain of 9HP's over the same dyno test with a 750CFM 4bbl carb and intake. The custom casted aluminum intake manifold is a medium rise dual plane with CNC machined surfaces and fits non-vortec 1955-86 small block Chevy engines. The custom tuned Holley carbs are fully assembled with fuel lines and installed on the intake. The progressive linkage is also installed, timed and adjusted for headache free installation. The front and rear carbs are Holley 325 cfm and the center carb is an electric choked Holley 350 cfm. The carbs are topped off with 3 rectangular K&N filters and polished finned aluminum caps.
