Pure Grunt
Dart sells intakes designed for the tall-deck block, but we opted to use Dart's spacers (PN 622100002) so that we could use any normal manifold. They needed significant massaging on the Bridgeport mill at Dougan's to get them to fit properly, and two sets of intake gaskets are needed (Fel-Pro PN 1206, in this case). The gap at the end seals is too big to bridge with RTV alone, so Jeff Jacobs stuck together two sets of the adhesive cork-end seals and glued them in with RTV. The taller manifold position will also require a distributor with an adjustable slip collar, and we used MSD PN 85561. View Related Article
