Has anyone looked into phenolic spacers?
Phenolic is a compound made from pressed canvas and resin that prevents heat transfer that is used in racing machines as a carb, TB, fuel pump, manifold spacer. A phenolic spacer between the upper and lower intakes would (a) greatly reduce heat transfer to the upper manifold, extending the life of the upper, and have a cooler fuel - air mixture (increasing hp), and (b) increase torque by increasing the runner legnth (however there will be a hp loss at the upper rpm range). Will this work? Not? Why or why not?
