carb heat shield needed
« on: December 14, 2022, 06:59:54 PM »
Getting ready to fire up one of my nailheads and in need of a heat shield that fits under the rear carb on a dual quad carb setup . Anyone know where to get one ?
Also in need of another dual quad linkage setup that goes between the two carbs .

No heat shield is needed on the 2x4 manifold!.... that U-shaped passage isn't drilled for exhaust gasses.
But the Martins are the usual source for those, www.nailheadbuick.com

Repo linkage has been avail on eBay for a number of years from 2 sellers, here's one:

There is an early and late style,the difference is the block slider on the front carb. Early used the block, later ones used a u-shaped bracket. I've heard the change was made due to the block having a tendency to bind up.
