Using a old AMC intake on your newer one.......PICTURE
you will need to move the holes up and in, to reference this look to an intake gasket. The middle 2 holes on both sides of the gasket are slotted. Here is a R4B intake i modified to fit 71-later dogleg heads. Now it will fit all years. Kinda cool mod! You can pick up a old R4B from ebay.com for around $250-$400 they are a med rise HUGE PORT 360 degree dual port intake.....WHEW!!!
