Man another 420 intake.... We should start a post to see who all has a 420 intake.... JimS from MP told me at PRI show only 29 of those manifolds were ever cast.... I was blown away by that low # because I've owned about 5 of them at one time or another. I can think of at least 6 people that have them on their cars at the moment.... & I get at least one call a week from GM guys looking for them.
