Redline slant 6 holley 4 barrel Intake manifold.

That intake is for the Slant-6, and for the money I'd buy the Offenhauser item instead—assuming I needed a 4-barrel carb on my Slant-6, which I probably wouldn't.

$414. bucks …...gosh damn, those REALLY got pricey.

I must be getting old because I remember when those were considerably less.
