Re: Part # for 5.7L Vortec Cast Iron 4 bbl Intake Manifold from GM Parts?
GM doesn't make a cast iron intake 4brl intake for vortec heads, that I know about. There is a low-profile cast-iron for q-jet (not gm) that you will find. Here is what Gilbert Chevy says about it:
GILBERT CHEVROLET no longer carries this part.
The manufacturer was unable to maintain our quality standards.
Do not call us about this intake.
We have no intension of ever ordering or selling this intake again due to manufacturing flaws which cause ourselves and our customers grief. Were all of these intakes flawed to the point of causing problems? No, but a large percentage were and the quality never improved during the time we were selling these.
If you are insistent on risking your time and money on this low quality produced intake, then call 806-983-3774.
GILBERT CHEVROLET is searching for a suitable replacement that both meets our quality standards and falls within the same price range of under $200.00, but so far, there doesn't appear to be any.
SBC Cast Iron Vortec, Dual Plane Intake Manifold. Designed to work with the L31 Vortec heads, Part Number: 12558060. This intake has an out of the box weight of 43 lbs. It is recommended for Chevy enthusiasts and for racers competing in classes which require a cast iron intake manifold. It is also suited to marine applications because cast iron is less susceptible to corrosion damage than aluminum. This is a non-GM part that GILBERT CHEVROLET had specially obtained for these applications but no longer sells due to quality problems.
