===Intake manifolds=== The 4V intake from the 250 and the 327 will bolt to the 287, which had no factory 4V option. The intake carb pattern is standard Holley [excluding the '57 models with the Carter WCFB, which has a smaller carb bolt pattern], and because the factory Holley 4150C used is only in the 450-500 cfm range (about right for the 250), it's easy to bolt a much more reasonably sized 600-650 cfm carb on the 287/327. There are no aftermarket intakes made, though I have seen a rare three deuce intake once, I think it was made by Fenton, but not sure. Whereas the Rambler V8 intake manifold is a 'free-standing,' 'air-gap' design with a separate lifter valley cover, AMC Gen-2 intakes can be adapted by cutting to remove the water and exhaust crossovers and fabricating 1/4" spacer/adapter plates for each side. The ports aren't an exact match, but can be matched with the 1/4" plate. A small block Chevy intake can also be adapted, but the V angles are different and the adapter plates must be fabricated to match the angle also. The ports aren't an exact match, but can be matched within the 1/4" plate.
