This is a premium CNC machined aluminum 4 barrel dual plane intake manifold.
I first started purchasing this manifold 10 years ago. Since then there has been a few tweaks to the casting that have upped the performance. I have personally seen this manifold pickup 32 hp without giving up any low end torque; just by switching the manifold!
I have been told this manifold is worth as much as 71 hp when you port match your cylinder heads, and fine tune your engine. I\'ve personally seen 56 hp after port match and fine tune.
Let the pictures tell the story for you. This beautiful casting that has been shot peened with stainless steel to keep a natural aluminum finish that won\'t change colors and rust, like iron shot will; and makes cleanup easy.
Every surface has been CNC machined to .000023 of an inch, so you don\'t need to worry about proper fitment. Using diamond cutters this manifold has smooth clean surfaces, you can take the manifold on and off as many times as you want while tuning; without destroying your gasket.
One of the more important things; The port matching. This manifold had been Port matched, and ready to put on your engine and run! Unlike other Y-block manifolds this has the heat riser on bottom, as well as other OE features.
The manifold has been pressure tested in the water jacket, heat riser, upper & lower plenum to 60 psi.
This manifold is highly detailed, what you see in the picture is the same quality you will receive. I don\'t & won\'t take pictures of items that are not representative of the piece you will receive.
I have used other aftermarket Y-block manifolds, and I can tell you without a doubt; this manifold is the best piece available. If you\'re tired of other manifolds that have weird names cast on them, no heat riser, rough casting, misaligned ports and leaks; this is the manifold for you.
