Manifold
My Tall Deck DART Tunnel Ram,used a Standard Deck Dist.This was a High Dollar T/Ram about 1100.00 new.And,i was Definatly a 9.800 Deck Height Dist.even though i run my Mag off the Front of the Motor,i still have a Oil Pump Drive in place of the Stock Dist.
When i Called Dart,i was told that all of there Manifolds where machied for a 9.800 Deck???
Maybe,your manifold went out the Back Door?
