Shield also stops any fuel spillage onto your headers cutting your chances of your pride and joy going up in flames (anyone with sidedraughts should have a fire extinguisher handy at all times). Best way is not to go between the carbs and manifold, there is enough problems with air and fuel leaks there, go off the 4 screws holding the pump cover on the bottom of each carb, that way the shield moves with the carbs as they flex on the manifold.

Long stroke, short rod. The ultimate sleeper combo. Twin Weber DCOE 40s.

Yes, it keeps the fuel bowls from overheating. But do it the way Datsun did with the twin-carb A12. Put the plate on carb-to-manifold face. In Japan nowadays they usually have a l-shaped heat shield for the DCOE manifolds. It goes up like the stock twin-carb heat shield, and also bends under the carbs completly, like this one.

Not much of a sleeper with that sort of induction!!!

Is is using an a14 crank? or offset ground crank?

Im heading the Dodgeman direction a12 early with a14 crank
and a12a rods but impco lpg unit and now convinced on closed
chamber big valve a14 head with bigger inlet manifold perhaps
an L series A series Hybrid manifold.
